RESUMO

Antimicrobial peptides (AMPs), often referred to as nature's antibiotics, are ubiquitous in living organisms, spanning from bacteria to humans. Their potency, versatility, and unique mechanisms of action have garnered significant research attention. Unlike conventional antibiotics, peptides are biodegradable, adding to their appeal as potential candidates to address bacterial resistance in livestock farming-a challenge that has been under scrutiny for decades. This issue is complex and multifactorial, influenced by a variety of components. The World Health Organization (WHO) has proposed a comprehensive approach known as One Health, emphasizing the interconnectedness of human-animal-environment relationships in tackling such challenges. This review explores the application of AMPs in livestock farming and how they can mitigate the impact of this practice within the One Health framework.

RESUMO

Resumen: La visión antropocéntrica del ser humano ha llevado a la explotación de animales para satisfacer sus necesidades, tanto primarias (como la alimentación) como secundarias (como el entretenimiento), sin preocuparse por su sufrimiento o bienestar. Sin embargo, las teorías de la evolución de Lamarck y Darwin borraron la dicotomía humano-animal y colocaron al primero como una especie más dentro de toda la diversidad biológica. Hans Jonas afirmó que las diferencias entre los humanos y los otros animales estaban en el grado de complejidad y no en las capacidades, contribuyendo a la idea de una continuidad biológica desde un origen común. La similitud anatomofisiológica, la presencia de mediadores químicos de dolor, los cambios bioquímicos y fisiológicos ante situaciones dolorosas, además de la respuesta favorable al uso de medicamentos analgésicos, demuestran que los demás animales sienten dolor y padecen sufrimiento. La Declaración de Cambridge sobre la consciencia destaca que no es necesario poseer neocórtex para ser considerado como sintiente, lo que ha llevado a analizar esta capacidad, inclusive, en muchos invertebrados. ¿Los animales sienten? Invariablemente la respuesta es sí. Es importante tener consideración de ello para evitar su sufrimiento, tal y como se propone en la teoría sensocéntrica de Peter Singer, en caso contrario, podríamos ser señalados de discriminación, que, por estar asociada a la pertenencia a una especie biológica, se denomina especismo.

Abstract: The anthropocentric view of life has led to the exploitation of animals to satisfy the human needs, primary (such as food) and secondary (such as entertainment), without regard for their suffering or well-being. However, Lamarck's and Darwin's theories of evolution erased the dichotomy between human and animal, placing the former as just another species within the entire biological diversity of life. Hans Jonas asserted that the differences between humans and other animals lie in the degree of complexity and not in capabilities, contributing to the idea of biological continuity from a common origin. The anatomic and physiological similarities, the presence of chemical pain mediators, the biochemical and physiological changes in painful situations, as well as the positive response to the use of analgesic medications, demonstrate that other animals feel pain and suffer. The Cambridge Declaration on consciousness emphasizes that it is not necessary to possess a neocortex to be considered sentient, which has led to the analysis of this capacity even in many invertebrates. Do animals feel? Invariably the answer is yes. It is important to consider this to avoid their suffering, as proposed in Peter Singer's sensocentrism theory. Otherwise, we could be accused of discrimination, which, based on species membership, is called speciesism.

RESUMO

Animal hoarding and human consumption by dogs have been important but often understudied aspects of the human-animal bond that can be addressed within a One Health framework. No scientific report has focused on dog scavenging on animal hoarders to date, despite isolated reports of dog scavenging on human remains, mostly due to starvation. The phenomenon has been approached as a confounding factor for human forensics. In 2014, the Animal Protection Department of Curitiba City was called to rescue and handle ten small dogs which had scavenged for a week on the human remains of their elderly owner, a potential animal hoarder. At inspection, three dead dogs in early putrefaction were also found in the household. Human autopsy revealed body putrefaction and lack of soft organs. Along with the dental arch, DNA testing was performed on the remains for official deceased identification. Due to the potential public health risks of aggression toward frail human beings and for the control of zoonotic diseases, all ten dogs were euthanized. Subsequent investigations by the crime scene police, homicide police, and autopsy services were unable to establish or rule out natural death, criminal or suicidal poisoning, zoonotic disease (rabies), fatal dog attack, or fatal accidental trauma. A general protocol has been proposed for future approaches to dog scavenging and suspicious killing of animal hoarders, as well an assessment for the potential adoption or euthanasia of animals owned by hoarders in these circumstances.

RESUMO

SUMMARY: In veterinary medicine, impressive technological advances in biochemistry, genetics and molecular biology have led to a reduction in the amount of time spent teaching anatomy and a shift toward anatomical research. As classically trained veterinary anatomists began to retire at the beginning of the 2000s, it became evident that there would be a shortage of qualified anatomists. This coincides with the increase in the hiring of recent graduates with general education experience and no specialization in the area. The aim of the study is to characterize the Chilean veterinary anatomy educator with an emphasis on their training and the academic environment they work in. Data were collected through a survey targeting a diverse population of university educators who teach content related to veterinary anatomy in Chile. The results showed that the Chilean veterinary anatomist has reached the master's level, with a wide range of continuous training experiences, from which it is perceived that he has acquired his anatomical and teaching skills. Furthermore, despite his self-perception as an educator/researcher, the evidence showed that research in veterinary anatomy is still in its infancy. However, strengths were identified related to the varied use of teaching resources, participation in the community and the dissemination of anatomical knowledge.

En medicina veterinaria, los impresionantes avances tecnológicos en bioquímica, genética y biología molecular han llevado a una reducción en la cantidad de tiempo dedicado a la enseñanza de la anatomía y un cambio hacia la investigación anatómica. Cuando los anatomistas veterinarios de formación clásica comenzaron a jubilarse a principios de la década de 2000, se hizo evidente que habría escasez de anatomistas cualificados. Esto coincide con el incremento en la contratación de recién egresados con experiencia en educación general y sin especialización en el área (licenciados, tesistas, etc.). El objetivo del estudio es caracterizar al educador de anatomía veterinaria chileno con énfasis en su formación y el ambiente académico en el que se desempeña. Los datos fueron recolectados a través de una encuesta dirigida a una población diversa de docentes universitarios que imparten contenidos relacionados con la anatomía veterinaria en Chile. Los resultados muestran que el anatomista veterinario chileno ha alcanzado el nivel de maestría, con una amplia gama de experiencias de formación continua, a partir de las cuales se infiere que ha adquirido sus competencias anatómicas y docentes. A pesar de su autopercepción como educador/investigador, la evidencia demostró que la investigación en anatomía veterinaria aún se encuentra en ciernes. No obstante, se identificaron fortalezas en actividades relacionadas con el uso variado de recursos didácticos, la participación en la comunidad y la difusión del conociminto.

RESUMO

Three-dimensional (3D) printing is a new method for creating human and veterinary anatomical models, which makes the education of students and professionals in the health area more complete, in addition to helping the patients themselves understand. In the area of cardiology, this technique can efficiently help the assessment of cardiac alterations for the patient during medical consultations, tying a feeling of involvement with the medical team. Likewise, it is possible to use 3D printing to understand the echocardiographic technique, where conceptual knowledge of the anatomy of the heart and the ability to translate a two-dimensional ultrasound image into a 3D idea is required. This research aimed to develop printable 3D cardiac models, to demonstrate cardiac sections used in echocardiography and use them to teach dog owners, evaluating their suitability as a tool for a better understanding of the echocardiographic exam. The 3D cardiac models were validated by dog owners through an evaluation questionnaire prepared on a Likert scale, after monitoring the echocardiographic examination with an explanation by the echocardiographer using the printed models. A total of 30 dog owners participated in the study. In all seven questions of the questionnaire, the vast majority of positive responses were observed, with partial or total agreement by the participants. These results showed that the use of 3D printed models is effective in improving the understanding of the echocardiographic examination and is feasible in the daily workflow.(AU)

A manufatura aditiva ou impressão 3D é um novo método para a criação de modelos anatômicos humanos e veterinários, que torna a educação de alunos e profissionais da área da saúde mais completa, além de auxiliar o entendimento dos próprios pacientes. Na área da cardiologia, esta técnica pode auxiliar de maneira eficiente a avaliação das alterações cardíacas para o paciente durante as consultas médicas, atrelando um sentimento de envolvimento com a equipe médica. Da mesma maneira, é possível utilizar a impressão 3D para o entendimento da técnica ecocardiográfica, onde é necessário conhecimento conceitual da anatomia do coração e a capacidade de traduzir uma imagem de ultrassonografia bidimensional em uma ideia tridimensional. Este artigo teve como objetivo desenvolver modelos cardíacos 3D imprimíveis, com o intuito de demonstrar cortes cardíacos utilizados na ecocardiografia e utilizá-los para ensinar os tutores de cães, avaliando sua adequação como ferramenta para melhor compreensão do exame ecocardiográfico. Imagens em DICOM de um exame de tomografia computadorizada de uma cadela foi adquirida para criação, edição e impressão dos diferentes modelos em 3D, que representam os cortes ecocardiográficos. Os modelos cardíacos em 3D foram validados por tutores de cães por meio de um questionário de avaliação elaborado em uma escala Likert, após acompanhamento do exame ecocardiográfico com uma explicação pelo ecocardiografista utilizando os modelos impressos. Um total de 30 tutores de cães participaram do estudo. Em todas as sete perguntas do questionário, foram observadas em sua grande maioria respostas positivas, sendo elas com concordância parcial ou total dos participantes. Até o momento não foram encontrados na literatura estudos com modelos de coração desenvolvidos para a educação clínica dos tutores de cães. Os resultados revelam que o uso dos modelos impressos em 3D é eficaz para melhorar a compreensão do exame ecocardiográfico e é viável no fluxo de trabalho diário.(AU)

RESUMO

Veterinary forensics is becoming increasingly important in the acquisition of evidence in cases of animal cruelty, unlawful killing, violation of wildlife law and medical malpractice. However, although forensic veterinary necropsy is one of the main techniques for gathering information about actions that have resulted in the unlawful killing of an animal, forensic necropsy of exhumed remains is rarely performed. We hypothesized that necropsy of exhumed animals can provide valuable information for the elucidation of cause of death. Hence, the present study aimed to describe the pathological changes observed in the necropsies of eight exhumed companion animals and to determine the frequencies of causes of death and diagnoses. This retrospective and prospective study was performed during the period 2008-2019. The causes of death of six of the eight disinterred animals were attributed to neurogenic shock (37.5 %), respiratory failure (25 %) and hypovolemic shock (12.5 %), with 50 % of necropsies providing conclusive diagnoses of physical/mechanical lesions and 25 % of infectious disease. The deaths of two animals could not be elucidated because of the advanced state of putrefaction. Ancillary testing comprised computed tomography (50 %), radiography (25 %), immunohistochemistry together with polymerase chain reaction/sequencing (12.5 %) and toxicology (12.5 %). The results support our original hypothesis since it was possible to observe macroscopic alterations that disclosed new information about the events connected with the demise of 100 % of the animals and to achieve irrefutable conclusions about the circumstances of death in 75 % of the studied cases.

RESUMO

ABSTRACT: Ethical and moral issues surround the practice of animal euthanasia, which often damages the veterinarian's mental health, leading to psychological problems and even suicide. This study aimed to evaluate veterinarians' perceptions about euthanasia and the possible implications of the practice for their mental health and seek to identify gaps in the training of these professionals. Data collection occurred by applying an online questionnaire sent to veterinarians working in the Brazilian territory. Among the 243 participants, 78% said they did not have classes that broadly addressed the practice of animal euthanasia and dysthanasia during undergraduate disciplines; in addition, 71% claimed that they did not address subjects such as medical ethics, psychology, mental health, and verbal communication. The vast majority (90%) considered not trained to deal with patient death, and 67% have already questioned whether the procedure was the best alternative. The presence of sadness after performing euthanasia was frequent among participants. Small animal clinicians were more susceptible to the presence of this feeling when compared to a veterinarian from other areas. Most veterinarians (86%) believed that the practice of animal euthanasia poses risks to the performer's mental health, and 89% claimed that it influences their mental health. 17% of the participants were using controlled medications during the research period. So, given these findings, it is evident that animal euthanasia negatively affects the mental health of those who perform it. Measures are needed to minimize the impacts arising from the practice, aiming to improve this population's health and well-being.

RESUMO: A prática da eutanásia animal é circundada por questões éticas e morais, o que resulta, muitas vezes, em prejuízo à saúde mental do veterinário, podendo levar ao desenvolvimento de problemas psíquicos e mesmo ao suicídio. O presente trabalho teve como objetivo avaliar as percepções do médico veterinário a respeito da eutanásia e as possíveis implicações da prática à sua saúde mental, além de buscar identificar lacunas acerca do tema na formação destes profissionais. A coleta dos dados ocorreu mediante aplicação de questionário online encaminhado a médicos veterinários atuantes no território brasileiro. Dentre os 243 participantes, 78% afirmaram não ter tido durante a graduação disciplinas que abordassem de forma ampla a prática da eutanásia e distanásia animal; além disso, 71% alegaram que conteúdos como ética médica, psicologia, saúde mental e comunicação verbal não foram tratados. A grande maioria (90%) considera não ter sido preparado para lidar com a morte de seus pacientes e 67% já questionaram se o procedimento era o melhor a se fazer naquele momento. Á presença de tristeza após realização de uma eutanásia apresentou-se de forma frequente entre os participantes. Os clínicos de pequenos animais mostraram-se mais suscetível à presença deste sentimento quando comparados aos veterinários de outras áreas. A maior parte dos médicos veterinários (86%) acredita que a prática da eutanásia animal pode oferecer riscos a saúde mental do realizador e 89% afirmam que a mesma pode ter influencia sobre sua saúde mental. Sendo que, 17% dos participantes estavam fazendo uso de medicamentos controlados durante o período da pesquisa. Diante desses achados, evidencia-se que a prática da eutanásia animal repercute negativamente na saúde mental de quem a executa, sendo necessárias medidas que minimizem os impactos advindos da prática, visando melhoria na saúde e bem-estar desta população.

RESUMO

Gastrointestinal parasitism by helminths and protozoa poses risks to animal and human health owing to clinical changes and transmission of potentially zoonotic agents. Thus, the present study aimed to verify the occurrence of gastrointestinal parasites in dogs from the municipality of Cuiabá, Mato Grosso, Brazil, using coproparasitological tests. From June 2021 to April 2022, faecal samples were collected from domestic dogs at the Veterinary Hospital and Animal Protection Shelters in the Cuiabá municipality. A semi-structured questionnaire was applied to the owners and those responsible for the shelters to analyse the factors associated with gastrointestinal parasitism. A total of 353 faecal samples were collected and subjected to parasitological flotation and sedimentation techniques. Data were analysed using the chi-squared test and exploratory factorial analysis. The occurrence of gastrointestinal parasitism was 22.66% and the parasites found alone or in mixed infections were Ancylostoma spp., Trichuris vulpis, Toxocara spp., Dipylidium caninum, Cystoisospora spp., Giardia duodenalis, and coccidia. It was concluded that the occurrence of gastrointestinal parasites in dogs is frequent, and the variables associated with these infections were source origin, breed, age, coexistence with other animals, and dull fur.(AU)

RESUMO

Extended spectrum ß-lactamase (ESBL)-producing Klebsiella pneumoniae is a medically important pathogen that commonly causes human nosocomial infections. Since veterinary emergency and critical care services have also significantly progressed over the last decades, there are increasing reports of ESBL-producing K. pneumoniae causing hospital-associated infections in companion animals. We present microbiological and genomic analysis of a multidrug-resistant ESBL-positive K. pneumoniae (LCKp01) isolated from a fatal infection in a dog admitted to a veterinary intensive care unit. LCKp01 strain belonged to the sequence type ST392 and displays a KL27 (wzi-187) and O-locus 4 (O4). A broad resistome and presence of the bla CTX-M-15 ESBL gene were predicted. SNP-based phylogenomic analysis, using an international genome database, clustered LCKp01 (60-80 SNPs differences) with K. pneumoniae ST392 from human and animal infections, isolated at 4-year interval, whereas phylogeographical analysis confirmed successful expansion of ST392 as a global clone of One Health concern.

RESUMO

Veterinarians, among other health professionals, are considered health professionals at high risk of exposure to and contraction of COVID-19. The main objective of this study is to assess changes in the clinical practices of veterinarians during the COVID-19 pandemic around prophylactic and biosafety measures, as well as to evaluate changes in workload and cost-benefit ratio. An online questionnaire was sent to veterinary professionals from July 2020 to July 2021 using Google Forms. A total of 1134 veterinarians answered the questionnaire on clinical experiences and biosafety practices during the COVID-19 pandemic. Veterinarians changed their routine clinical practices, as there was a reduction in working hours, and applied new patient approaches and advice to their owners, as well as restricting the number of people allowed inside. Biosafety measures were added in their workplaces, with an increase in the use of personal protective equipment. COVID-19 tests were administered at least once in 19.0%, and more than once in 9.5% of the respondents. Flu symptoms were present in 23.8% of the respondents, and 31.0% of the veterinarians attended to COVID-19 positive pet owners. Therefore, most veterinarians altered their routine practices, and some were exposed to sources of COVID-19 infection.

Os médicos veterinários, entre outros profissionais de saúde, são considerados profissionais de saúde sob alto risco de exposição e contração do COVID-19. O objetivo principal do presente estudo foi avaliar as mudanças na prática clínica de médicos veterinários durante a pandemia de COVID-19 em torno das medidas profiláticas e de biossegurança, assim como avaliar as mudanças na carga de trabalho e a relação custo-benefício. De julho a dezembro de 2020, um questionário online foi enviado aos profissionais por meio da ferramenta Formulários Google. Um total de 1.134 veterinários responderam ao questionário relacionado às experiências clínicas e práticas de biossegurança durante a pandemia COVID-19. Os médicos veterinários mudaram suas práticas clínicas rotineiras, pois houve redução da jornada de trabalho, novas abordagens dos pacientes e orientações aos proprietários, além da restrição do número de pessoas nos locais. Medidas de biossegurança foram adicionadas aos locais de trabalho, com aumento do uso de equipamentos de proteção individual. Os testes COVID-19 foram realizados pelo menos uma vez em 19,0% e mais de uma vez em 9,5% dos entrevistados. Sintomas de gripe estavam presentes em 23,8% dos profissionais entrevistados e 31,0% dos veterinários atendiam tratadores de animais positivos para COVID-19. Portanto, a maioria dos veterinários alterou suas práticas de rotina e alguns foram expostos a fontes de infecção COVID-19.

RESUMO

Cannabis is used in the treatment of several human conditions; however, its use is still less explored in veterinary medicine. This systematic review aims to summarize the evidence of efficacy and safety of the use of cannabis for the treatment of animal disease. A literature search was performed for studies published until 16 March 2021 in five databases. Randomized clinical trials (RCTs) that reported the efficacy or safety of cannabis in the treatment of animal disease were included. The RoB 2 Tool was used to assess the risk of bias. A total of 2427 records were identified, of which six studies fully met the eligibility criteria. RCTs were conducted in dogs with osteoarthritis (n = 4), with epilepsy (n = 1), and with behavioral disorders (n = 1). All studies used cannabidiol (CBD) oil in monotherapy or in combination with other drugs. Studies used CBD at 2 or 2.5 mg kg-1 twice daily (n = 4), orally (n = 5), during 4 or 6 weeks (n = 3), and compared CBD with placebo (n = 5). CBD significantly reduced pain and increased activity in dogs with osteoarthritis (n = 3). Moreover, CBD significantly reduced the frequency of seizures in dogs with epilepsy (n = 1) and the aggressive behavior of dogs (n = 1). Although promising results were identified, studies were heterogeneous and presented risks of bias that required caution in the interpretation of findings. Therefore, there was some evidence to support the use of CBD in dogs with osteoarthritis to reduce pain and increased activity, but limited evidence against epilepsy and behavioral problems. In addition, CBD was well tolerated with mild adverse effects. More RCTs with high quality of evidence are needed, including greater numbers of animal subjects, additional species, and clear readout measures to confirm these findings.

RESUMO

INTRODUCCIÓN: La toxoplasmosis es una enfermedad zoonótica cuyo contagio se produce por vía oral por ingestión de quistes al consumir carne contaminada o al tener contacto con heces de felinos contaminadas con ooquistes. Con menor frecuencia, se adquiere por transmisión vertical o por trasplante de órganos infectados. En Chile, existen estudios serológicos en personas sanas e inmunodeprimidas, pero no en grupos de riesgo ocupacional, como son los estudiantes de Medicina Veterinaria. OBJETIVO: Determinar la seroprevalencia para T. gondii en estudiantes de Medicina Veterinaria de una universidad ubicada en el centro-sur del país, y ver su asociación con variable intrínsecas. MÉTODOS. Se tomaron muestras de sangre a 74 estudiantes de una universidad del centro-sur de Chile. Se determinó la presencia de anticuerpos específicos clase IgG contra Toxoplasma gondii mediante la técnica de inmunoanálisis por quimioluminiscencia en fase solida secuencial. RESULTADOS. Del total de alumnos, 16 fueron seropositivos lo que equivale a 21,6%, el mayor número de estudiantes seropositivos fue de sexo femenino (75%), se encontraban en el rango etario entre 24 y 26 años de edad (43,7%), todos consumían carne y verduras (100%) y realizaban la recolección de heces de gatos sin protección 50 (68,7%). CONCLUSIONES. Los resultados obtenidos demuestran la presencia de anticuerpos contra T. gondii en alumnos de Medicina Veterinaria. Según el conocimiento de los autores, es el primer estudio serológico para toxoplasmosis realizado en estudiantes universitarios de Medicina Veterinaria en Chile.

BACKGROUND: Toxoplasmosis is a disease that results from infection with the Toxoplasma gondii parasite, one of the world's most common parasites. The zoonotic infection usually occurs by eating undercooked contaminated meat or by contact with contaminated cat feces. A few studies of toxoplasmosis in healthy and immuno-compromised persons were done in Chile, but investigations related to occupational risk groups, such as Veterinary Medicine students were not studied. AIM: Determine the seroprevalence for T. gondii in Veterinary Medicine students at a university located in the center-south of the country, and evaluated to association with intrinsic variables. METHODS: Peripheral blood samples were taken from 74 veterinary students from a university in south-central Chile. Immunoassay with sequential chemiluminescent was used as diagnostic technique. RESULTS. Of the total number of students, 16 were seropositive, which is equivalent to 21.6%, the largest number of seropositive students was female (75%), they were in the age range between 24 and 26 years of age (43.7%), all consumed meat and vegetables (100%) and collected pet cat feces without protection 50 (68,7%). CONCLUSIONS: The results obtained show the presence of antibodies against T. gondii in Veterinary Medicine students. To the authors' knowledge, it is the first serological study for toxoplasmosis performed in university students of Veterinary Medicine in Chile.

RESUMO

The emergence of the COVID-19 pandemic reinforced the central role of the One Health (OH) approach, as a multisectoral and multidisciplinary perspective, to tackle health threats at the human-animal-environment interface. This study assessed Brazilian preparedness and response to COVID-19 and zoonoses with a focus on the OH approach and equity dimensions. We conducted an environmental scan using a protocol developed as part of a multi-country study. The article selection process resulted in 45 documents: 79 files and 112 references on OH; 41 files and 81 references on equity. The OH and equity aspects are poorly represented in the official documents regarding the COVID-19 response, either at the federal and state levels. Brazil has a governance infrastructure that allows for the response to infectious diseases, including zoonoses, as well as the fight against antimicrobial resistance through the OH approach. However, the response to the pandemic did not fully utilize the resources of the Brazilian state, due to the lack of central coordination and articulation among the sectors involved. Brazil is considered an area of high risk for emergence of zoonoses mainly due to climate change, large-scale deforestation and urbanization, high wildlife biodiversity, wide dry frontier, and poor control of wild animals' traffic. Therefore, encouraging existing mechanisms for collaboration across sectors and disciplines, with the inclusion of vulnerable populations, is required for making a multisectoral OH approach successful in the country.

RESUMO

Industrial food animal production practices are efficient for producing large quantities of milk, meat, and eggs for a growing global population, but often result in the need to alter animals to fit a more restricted environment, as well as creating new animal welfare and health problems related to animal confinement in high densities. These practices and methods have become normalized, to the extent that veterinarians and others embedded in these industries rarely question the ethical challenges associated with raising animals in this fashion. Moral 'lock-in' is common with those working in food animal industries, as is the feeling that it is impossible to effect meaningful change. Animal welfare issues associated with the industrialization of food animal production are 'wicked problems' that require a multi- and transdisciplinary approach. We argue that veterinarians, as expert animal health and welfare advocates, should be critical stakeholders and leaders in discussions with producers and the food animal sector, to look for innovative solutions and technology that will address current and future global sustainability and food security needs. Solutions will necessarily be different in different countries and regions, but ethical issues associated with industrial food animal production practices are universal.

RESUMO

Animal shelters are places with a high risk of exposure to infectious diseases due to the high density, population dynamics of the shelter, and the stress to which dogs and cats are subjected. The immunization process through vaccines is an essential component in the prevention and health and welfare management program for these animals. This review aims to evaluate the guidelines on vaccination of dogs and cats in shelter environments, highlighting points of comparison with the Brazilian reality.(AU)

Os abrigos de animais são locais com um alto risco de exposição às doenças infecciosas devido à alta densidade, à dinâmica populacional do abrigo e ao estresse a que os cães e gatos estão submetidos. O processo de imunização por meio das vacinas é um componente essencial no programa de prevenção e gestão de saúde e bem-estar para esses animais. Esta revisão tem como objetivo revisar as diretrizes sobre a vacinação de cães e gatos em ambientes de abrigos, ressaltando pontos de comparação com a realidade brasileira.(AU)

RESUMO

Animal abuse is a criminal offense in Brazil and can be dealt with by several government agencies, including municipal ones. Cases of animal abuse reported to the Department of Health Surveillance, of the Municipal Health Secretariat of Campo Magro, Paraná, Brazil, between March of 2019 and December of 2020 were analyzed to assess the most common forms of abuse and animals involved. A total of 140 complaints were received in this period; 132 were investigated, of which 81 were considered authentic. The most common form of abuse was neglect 64.2% (52/81). Cases of neglect were further classified into four types (although cases may be classified with more than one type), resulting in 106 classifications of neglect. Behavioral neglect was the most common form of neglect 33.9% (36/106). As more than one animal could be involved in each report, the 81 authentic cases involved a total of 471 animals. Dogs were the species most commonly affected 78.5% (370/471). The vast majority of animal abuse was perpetrated against adult animals. Statistically significant correlations were found between the sex and age of dogs and abuse and between species and the different forms of abuse for dogs and cats.(AU)

Os maus-tratos aos animais são considerados crime no Brasil e o atendimento desse tipo de ocorrência pode ser realizado por diferentes órgãos governamentais, incluindo os municipais. O presente trabalho analisa denúncias atendidas pelo Departamento de Vigilância em Saúde, da Secretaria Municipal de Saúde de Campo Magro, Paraná, Brasil, entre março de 2019 e dezembro de 2020 e avalia os tipos mais comuns de maus-tratos a animais e os animais envolvidos. Um total de 140 denúncias foram recebidas e 132 foram fiscalizadas, destas, 81 foram consideradas procedentes. A forma mais prevalente de maus-tratos foi a negligência com 64,2% (52/81). Os casos de negligência foram classificados em quatro diferentes tipos (cada caso pode ser classificado em mais de um tipo de negligência). O tipo mais frequente foi a negligência comportamental com 33,9% (36/106). Como mais de um animal podia estar envolvido em cada caso de maus-tratos, os 81 casos procedentes contabilizaram 471 animais envolvidos. A espécie canina foi a mais afetada, sendo 78,5% (370/471). A maior parte dos casos de maus-tratos foram cometidos contra animais adultos. Correlações estatísticas significativas foram encontradas entre o sexo e faixa etária dos cães em relação à ocorrência de maus-tratos e, também, entre a espécie e os diferentes tipos de maus-tratos para cães e gatos.(AU)

RESUMO

Background and Aim: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the global coronavirus pandemic (COVID-19) in humans in 2019. Although SARS-CoV-2 infection is primarily asymptomatic and transitory in companion animals, the role of these animals in the life cycle of the virus remains unclear. This study aimed to survey the first SARS-CoV-2 infection cases in pets, including a dog and three cats in São Paulo, Brazil. Materials and Methods: We invited COVID-19-positive pet owners to participate in the survey and obtained nasal, oropharyngeal, and rectal swab samples from their pets. These samples were placed in vials and subjected to a real-time quantitative polymerase chain reaction. In addition, the owners answered an epidemiological questionnaire, and the pets underwent clinical examination and monitoring. Results: Out of 49 sampled pets, 3/19 (15.8%) cats and 1/30 (3.3%) dogs tested positive, with wide variations in viral loads. Despite the limitations of size and non-randomized sampling, our results showed that cats are more susceptible than dogs to SARS-CoV-2 infection, presenting a cat: dog ratio of 4.8: 1. Only one cat presented mild and transitory respiratory symptoms. Conclusion: Although SARS-CoV-2 infection was detected in pets in the largest South American city and the COVID-19 epicenter at the time, these first detected pet cases displayed either none or mild clinical signs.

RESUMO

Empathy plays an important role in veterinarians' relationships with their patients, clients, and colleagues. Because it relates to greater clinical competence and facilitates the acquisition of information for diagnosing, prescribing therapies, and identifying and treating animal pain, empathy is an essential competence to be strengthened during professional training. The objective of this study was to evaluate the empathy levels of veterinary medicine students toward people and animals and to identify associated factors. The animal empathy scale and the Davis interpersonal reactivity index were applied through an electronic survey to first-, third-, and fifth-year students (n = 559) in three veterinarian medical schools in Colombia. A principal components analysis was performed to identify composite scores of human and animal empathy levels. The empathy toward humans total score ranged from 0 to 112, and the empathy toward animals total score was between 22 and 198. The average empathy scores for students were 89.67 ± 9.02 (mean ± SD; range: 60-115) and 115.01 ± 13.41 (mean ± SD; range: 67-165), respectively. The results suggest that empathy scores toward people are acceptable. Gender, university, program type, age, year of study, and diet were significantly associated with empathy levels toward animals. It is proposed that levels of empathy toward animals be strengthened by fostering a positive learning environment, developing ethical and animal welfare competencies, and increasing empathetic contact and hands-on experience with animals during the curriculum.
