RESUMO

Background: Breast neoplasms are among the most common neoplastic conditions affecting domestic animals and are considered the most common type of cancer affecting women, bitches, and cats. However, there are few reports on breast neoplasms in wild animals, and there is no record of their occurrence in armadillos worldwide. Breast neoplasms are hormone-dependent neoplasms that often cause lymph node and pulmonary metastases. The diagnosis is based on the patients history, complete physical examination, and complementary tests. Here we report a case of mammary neoplasia with pulmonary metastasis in an armadillo (Euphractus sexcinctus).Case: A senile female armadillo was referred to us for treatment with a history of hyporexia and nodules in both breasts. Ultrasonographic examination revealed a hypoechogenic nodular lesion with a cross-section of approximately 1.3 × 1.4 cm and well-defined borders. The lesion had a circumscribed aspect in the left mammary gland. In the right mammary gland, there was a heterogeneous lesion with cystic formations and anechoic content. Cytopathological examination of the nodules was performed by fine needle aspiration cytology and revealed the presence of epithelial cells with ovoid and aberrant nuclei, anisocariasis, binucleation, coarse chromatin, and a high nucleus to cytoplasm ratio suggestive of carcinoma. The animal had a lean body score due to hyporexia that had evolved to anorexia and was undergoing supportive treatment. Nevertheless, the animal died two months after the cytologic diagnosis. A necropsy was performed. Cutting of the breast nodules revealed a hardened pale yellow material. The animal had pronounced pleural effusion, hemorrhage, and numerous pale yellow nodules of various sizes with firm consistency throughout the lung parenchyma. It also had hepatomegaly and splenomegaly.[...](AU)

RESUMO

O mão-pelada (Procyon cancrivorus) é um carnívoro silvestre amplamente distribuído no Brasil, porém há escassez de informações sobre a anatomia e as alterações clínicas dessa espécie. Relata-se o caso de uma fêmea de mão-pelada de cativeiro de doze anos, encaminhada para exame tomográfico da coluna vertebral, com histórico de paralisia aguda de membros pélvicos. Após a realização do exame, a análise das imagens demonstrou extrusão discal no espaço intervertebral entre T13 e L1, com sinais de compressão da medula. Optou-se pelo tratamento cirúrgico, entretanto, o manejo no período pós-operatório foi dificultado. Não houve melhora significativa dos déficits neurológicos, e posteriores complicações secundárias agravaram o quadro clínico geral, que evoluiu para óbito. Destaca-se que os relatos de extrusão de disco intervertebral em animais silvestres são raros, não havendo descrições em mãos-peladas.(AU)

The crab-eating raccoon (Procyon cancrivorus) is a wild carnivore widely distributed in Brazil, but information about the anatomy and main diseases that affect this species is scarce. This paper describes the clinical and diagnostic aspects of a 12-year-old female raccoon referred to a CT scan of the thoracolumbar spinal segment after presenting signs of acute pain and paralysis of hind limbs. Analysis of the images revealed the presence of mineralized material within the vertebral canal at the level of the T13-L 1 intervertebral space, with signs of spinal cord compression. We opted for surgical treatment. However, post-operative care was difficult, there was no significant improvement in neurological deficits, and secondary complications worsened the clinical status, which eventually led to the death of the animal. It is worth noting that descriptions of intervertebral disc extrusions in wild animals are rarely mentioned in the literature, and there are no descriptions of their occurrence in raccoons.(AU)

El mapache (Procyon cancrivorus) es un carnívoro silvestre de amplia distribución en Brasil, aunque son escasas las informaciones relacionadas con la anatomía y las alteraciones clínicas de esta especie. El presente trabajo relata el caso de una mapache de doce años, mantenida en cautiverio, que fue derivada para la realización de un examen tomográfico de la columna vertebral, con histórico de parálisis aguda de miembros posteriores. El análisis de las imágenes demostró la presencia de una extrusión discal en el espacio intervertebral entre T13 y L1, con signos de compresión medular. Se decidió realizar el tratamiento quirúrgico, aunque el manejo postoperatorio se mostró complicado. No hubo mejoría significativa de las alteraciones neurológicas, y complicaciones secundarias fueron agravando el cuadro clínico general, que llevaron a la muerte del animal. Los relatos de extrusión de disco intervertebral en animales silvestres son raros, y no se encontraron descripciones en mapaches.(AU)

RESUMO

We investigated the Amblyomma fuscum load on a pullulating wild rodent population and the environmental and biological factors influencing the tick load on the hosts. One hundred and three individuals of Thrichomys laurentius were caught in an Atlantic forest fragment in northeastern Brazil, as part of a longitudinal survey on ticks infesting non-volant small mammals. Ticks (n = 342) were found on 45 individuals and the overall mean intensity of infestation was 7.6 ticks per infested rodent. Ticks were highly aggregated in the host population and the negative binomial distribution model provides a statistically satisfactory fit. The aggregated distribution was influenced by sex and age of the host. The microhabitat preference by T. laurentius probably increases contact opportunities between hosts and aggregated infesting stages of the ticks and represents important clues about the habitat suitability for A. fuscum.

RESUMO

O estudo epidemiológico de patógenos em populações selvagens no ambiente in situ e ex situ é fundamental para implementação de programas de prevenção, controle e monitoramento de enfermidades e para elaboração de políticas públicas de saúde pública e animal. O estudo foi realizado no zoológico do Parque Estadual de Dois Irmãos no período de janeiro a julho de 2011 onde foram coletados swabs anais e otológicos referentes a 29 carnívoros silvestres cativos do zoológico. Dos swabs otológicos analisados, 1/29 (3,4%) foi positivo para Malassezia pachy dermatis no exame direto. No exame microbiológico dos swabs otológicos, observou-se maior freqüência para bactérias do gênero Bacillus 16/29 (55,2%), seguida de Sta phylococcus 15/29 (51,7%), Escherichia coli 7/29 (24,1%), Streptobacillus 1/29 (3,4%), Micrococcus 1/29 (3,4%) e Klebsiella 1/29 (3,4%). Com relação ao exame presuntivo para o gênero Salmonella a partir das amostras de swab retal, observou-se positividade para seis raposas (Cerdocyon thous) e um guaxinim (Procyon cancrivorus). O isolamento de Salmonella spp. em C. thous e em P. cancrivorus indica um risco à saúde pública, principalmente para os profissionais do zoológico que trabalham diretamente com esses animais. Essa pesquisa reforça a importância da criação de estratégias de vigilância epidemiológica voltadas para a prevenção, controle e monitoramento de potenciais reservatórios de agentes etiológicos de doenças infecciosas e parasitárias no ambiente dos zoológicos.

The epidemiological study of pathogens in wild populations in the environment in situ and ex situ is essential for implementation of prevention, control and monitoring of diseases and for development of public policies for public and animal health. The study was conducted at the Zoo of Parque Estadual de Dois Irmãos, Recife/PE, Brazil, from January to July 2011, where we collected anal and otological swabs from 29 Zoo's captive wild carnivores. The analysis of the otological swabs showed that 1/29 (3.4%) were positive for Malassezia pachydermatis on direct examination. In the microbiological examination of otologic swabs we found mainly bacteriae of the genus Bacillus 16/29 (55.2%), followed by Staphylococcus 15/29 (51.7%), Escherichia coli 7/29 (24.1%), Streptobacillus 1/29 (3.4%), Micrococcus 1/29 (3.4%) and Klebsiella 1/29 (3.4%). Regarding the presumptive test for the genus Sal monella from rectal swabs, positive samples were observed in six foxes (Cerdocyon thous) and a raccoon (Procyon cancrivorus). The isolation of Salmonella spp. in C. thous and P. can crivorus indicates risks to public health, especially for zoo professionals who work directly with these animals. This research reinforces the importance of establishing surveillance strategies aimed at prevention, control and monitoring of potential reservoirs of the etiologic agents of infectious and parasitic diseases in the environment of zoos.

RESUMO

Between December 2007 and March 2009, small mammals were captured in 6 Atlantic Forest patches in Brazil. We assessed tick-host associations and whether they differ among forest strata, sites, seasons, and host age classes or between sexes. Moreover, we assessed the exposure of animals to Rickettsia spp. In total, 432 animals were captured and 808 ticks were found on 32·9% of them. Significant differences were found among host species, collection sites, and forest strata; microhabitat preference was a strong risk factor for tick infestation. The highest tick density rates were recorded in forest fragments settled in rural areas; 91·3% of the ticks were collected from animals trapped in these forest fragments. A high prevalence (68·8%) of antibodies to Rickettsia spp. was detected among animals. This study suggests that disturbed Atlantic Forest fragments provide an environment for ticks and small mammals, which are highly exposed to rickettsiae. It also indicates that forest patches settled in rural areas are usually associated with higher small mammal diversity as well as with higher tick density rates.
