RESUMEN

The Brazilian western Amazon is experiencing its largest laboratory-confirmed Oropouche virus (OROV) outbreak, with more than 6,300 reported cases between 2022 and 2024. In this study, we sequenced and analyzed 382 OROV genomes from human samples collected in Amazonas, Acre, Rondônia and Roraima states, between August 2022 and February 2024, to uncover the origin and genetic evolution of OROV in the current outbreak. Genomic analyses revealed that the upsurge of OROV cases in the Brazilian Amazon coincides with spread of a novel reassortant lineage containing the M segment of viruses detected in the eastern Amazon region (2009-2018) and the L and S segments of viruses detected in Peru, Colombia and Ecuador (2008-2021). The novel reassortant likely emerged in the Amazonas state between 2010 and 2014 and spread through long-range dispersion events during the second half of the 2010s. Phylodynamics reconstructions showed that the current OROV spread was driven mainly by short-range (< 2 km) movements consistent with the flight range of vectors. Nevertheless, a substantial proportion (22%) of long-range (>10 km) OROV migrations were also detected, consistent with viral dispersion by humans. Our data provide a view of the unprecedented spread and evolution of OROV in the Brazilian western Amazon region.

RESUMEN

Bovine neosporosis is a globally important disease, causing abortions and significant economic losses. In Brazil, studies on neosporosis in cattle are few and based on limited samples and/or from limited areas. We aimed to determine the herd and animal levels seroprevalence and associated factors for Neospora caninum infections in cattle from the state of Paraíba, Northeastern Brazil, using a planned sampling. Herds (n = 434) and cows aged ≥24 months (n = 1891) were randomly selected, and serum samples were tested with the immunofluorescence antibody test (IFAT) using as cut-off point the antibody titer 200. Herd-level and animal-level seroprevalences were 17.8% (95% CI = 14.3%-21.8%) and 18.1% (95% CI = 14.7%-22.1%), respectively. The factors associated with N. caninum infection were farm located in the Sertão mesoregion (Prevalence ratio [PR] = 2.37), mixed production (PR = 1.64), herd size of 34-111 animals (PR = 3.50) and herd size >111 animals (PR = 6.14). The results indicate high N. caninum circulation in the bovine population of the state of Paraíba, semiarid of Brazil, mainly in the Sertão mesoregion, where the highest apparent herd and animal-level prevalences of positive herds were identified. Control strategies should be adopted to mitigate the impact of disease on cattle production, as well as it's suggested the encouragement of conducting surveys in wildlife from Caatinga biome, mainly canids, to provide information on the importance of these animals on the epidemiology of bovine neosporosis.

RESUMEN

This study comprises a retrospective analysis of snakebites in the State of Amazonas, Brazil, from 2007 to 2017. Data were collected from the Notifiable Diseases Information System (NDIS). 17,056 snakebites were recorded in Amazonas between 2007 and 2017. During the study period, the Rio Negro and Tefé micro-regions had the highest accumulated incidence, while small municipalities such as São Gabriel da Cachoeira, Uarini and Alvarães presenting a high incidence rate during the same period. Snakes in the genera Bothrops and Lachesis caused 69.5% and 20.3% snakebites. Snakebites occurred more frequently in the Amazonian winter, between January and April, and most of the snakebite victims (78.6%) were men. The most affected individuals were between 20 and 39 years of age (59.4%). The time elapsed between snakebites and medical assistance varied from one to six hours (51.4%). 7,705 of the snakebite cases, were classified as moderate, 7,328 as mild, and 1,299 as severe. Of the 104 deaths that occurred in the period, Bothrops genus caused the highest mortality (68.3%). The State of Amazonas recorded both high numbers of snakebites in the period 2007-2017 and the time elapsed between snakebite and medical assistance, which may affect the clinical status of patients.

RESUMEN

A cross-sectional study was carried out to estimate the animal- and herd-level prevalence of bovine herpesvirus 1 (BoHV-1) infection in cattle in the State of Paraíba, and to identify risk factors associated with herd-level infection. The state was divided into three sampling strata, and for each stratum, the prevalence of herds infected with BoHV-1 was estimated through a two-stage sampling survey carried out from September 2012 to January 2013. In total, 2443 animals were sampled from 478 herds. A virus-neutralization test was used for BoHV-1 antibody detection. A Bayesian latent-class model was used to describe the data, taking into account imperfect diagnostic test characteristics and the non-independence of test results from animals within the same herd, and using a dynamic within-model risk factor selection method based on indicator variable selection. The adjusted herd-level prevalence was estimated to be 84% (95% CI: 80-88%) for the State of Paraíba, and the animal-level prevalence was estimated to be 73% (95% CI: 66-84%). Only five of the available risk factors were used by the model, with the three most influential being disposal of aborted foetuses (3.78, 95% CI: 1.11-13.85), sharing resources with other farms (3.0, 95% CI: 1.1-8,6), and a herd size of > 23 animals (2.5, 95% CI: 1.1-6.0). Our findings suggest that the animal- and herd-level seroprevalence of BoHV-1 infection in the State of Paraíba is high. While some risk factors such as herd size and sharing resources were identified as risk factors for BoHV-1 infection, these risk factors are initially likely to be of only minor relevance in a control programme due to the extremely high prevalence of infected farms. However, the results are relevant to the risk of reintroduction of disease on farms that have previously eradicated the disease.

RESUMEN

BACKGROUND: Bovine Viral Diarrhea Virus (BVDV) and Bovine Herpesvirus type 1 (BoHV-1) cause reproductive problems in cattle and restrictions on international trade in animals worldwide. Both infections were detected in cattle herds in the Paraíba state, Northeastern Brazil, however, the spatial distribution and geographic identification of positive herds for these viruses has never been examined. Therefore, the aim of this study was to describe the spatial pattern of apparent prevalence estimate and to identify spatial clustering of positive herds of BVDV and BoHV-1 infections in cattle herds from the state of Paraíba, Northeastern Brazil. RESULTS: The herd-level prevalence for BVDV and BoHV-1 infections in Paraíba were, respectively, 65.5% (95% CI: 61.1-69.7) and 87.8% (95% CI: 84.5-90.5). The average apparent within-herd prevalence of BVDV was 31.8% and of BoHV-1 was 62.4%. The predicted prevalence was highest (0.42-0.75) for BVDV in the west, north and eastern part of Sertão and in the central and eastern part of Agreste/Zona da Mata. For BoHV-1, the highest predicted prevalence (0.74-0.97) was in some local areas across Sertão and throughout the eastern part of Agreste/Zona da Mata. Six significant clusters were detected for BVDV, a primary cluster covering the eastern Sertão region, with 11 herds, radius of 24.10 km and risk relative (RR) of 2.21 (P <  0.001) and five smaller significant clusters, involving one or two herds in Agreste/Zona da Mata region with a high RR. A significant clustering of BoHV-1 positive herds (P <  0.001) was detected in Agreste/Zona da Mata region with a radius of 77.17 km and a RR of 1.27, with 103 cases. Consistency was found between kriging and SatScan results for identification of risk areas for BVDV and BoHV-1 infections. CONCLUSIONS: The clusters detected contemplated different areas of the state, with BVDV cluster located in the Sertão and BoHV-1 in Agreste/Zona da Mata stratum. Through the risk mapping, it was possible to identify the areas in which the risk is significantly elevated, coincided with areas where there are borders with other states and in which there is a high movement of animals.

RESUMEN

The aim of this survey was to identify spatial clustering of bovine cysticercosis-positive herds in the state of Paraíba. The state was divided into three sampling groups: sampling stratum 1 (Sertão mesoregion), sampling stratum 2 (Borborema mesoregion) and sampling stratum 3 (Zona da Mata and Agreste mesoregions), and 2382 cows aging ≥ 24 months from 474 farms were sampled. Serological diagnoses of bovine cysticercosis were initially done by means of indirect ELISA, and positive serum samples were confirmed by a immunoblot test. Herds were deemed positive for cysticercosis if they presented at least one positive animal in herds of up to 29 females, and two positive animals in herds with more than 29 females. The spatial clustering was assessed using the Cuzick-Edwards k-nearest neighbor method and spatial scan statistics. A significant clustering of positive herds was detected in the southern part of the Borborema mesoregion. Given that serological tests for bovine cysticercosis are not widely available, and also that replacement and maintenance of herds through animal purchases is common in the region, it can be concluded that prevention measures should be applied at herd level.

RESUMEN

Serological surveys based on a planned sampling on bovine viral diarrhea virus (BVDV) infection in Brazilian cattle herds are scarce. A cross-sectional study was carried out to determine herd- and animal-level seroprevalences and to identify risk factors associated with herd-level seroprevalence for BVDV infection in the State of Paraíba, Northeastern Brazil, from September 2012 to January 2013. The state was divided into three sampling strata, and for each stratum, the prevalence of herds infected with BVDV and the prevalence of seropositive animals was estimated by a two-stage sampling survey. In total, 2443 animals were sampled from 478 herds. A virus-neutralization test was used for BVDV antibody detection. A herd was considered positive when at least one seropositive animal was detected. The herd- and animal-level prevalences in the State of Paraíba were 65.5% (95% confidence interval (CI) = 61.1-69.7%) and 39.1% (95% CI = 33.1-45.6%), respectively. The frequency of seropositive animals per herd ranged from 10 to 100% (median of 50%). The risk factors identified were as follows: more than six calves aged ≤12 months (odds ratio (OR) = 3.72; 95% CI = 2.08-6.66), animal purchasing (OR = 1.66; 95% CI = 1.08-2.55), pasture rental (OR = 2.15; 95% CI = 1.35-3.55), and presence of veterinary assistance (OR = 2.04; 95% CI = 1.10-3.79). Our findings suggest that the implementation of control and prevention measures among farmers, with the aim of preventing dissemination of the agent in the herds, is necessary. Special attention should be given to addressing the identified risk factors, such as sanitary control prior to animal purchasing and to discourage the pasture rental, as well as to encourage the vaccination in the herds.

RESUMEN

An epidemiological survey aiming to determine the occurrence of anti-Leptospira antibodies and to identify risk factors was carried out in horses of the Pajeú microregion, state of Pernambuco. Sera from 100 horses from 38 properties in four counties in the region were examined by the microscopic agglutination test (MAT), using 24 Leptospira spp. serovars as antigens. Of the 100 samples tested, 28 (28%) were positive. Most prevalent serovars were Patoc (35.71%), Butembo (32.14%) and Sentot (14.30%). Supply of pasture as forage (odds ratio =7.80; 95% confidence interval - 95%CI 1.71-35.50; p=0.008) was identify as risk factor. It is suggested the need for studies on agent isolation and characterization of its pathogenicity, as well as it is recommended the rodent control in deposits of feed and environment.(AU)

Foi realizado um inquérito epidemiológico objetivando determinar a ocorrência de anticorpos anti-Leptospira e elencar os fatores de risco em equinos da microrregião do Pajeú, estado de Pernambuco. Foram examinados 100 soros de equinos provenientes de 38 propriedades de 4 municípios da região, pela prova de soroaglutinação microscópica (SAM), utilizando 24 sorovares de Leptospira spp. como antígeno. Das 100 amostras testadas, 28 (28%) foram reagentes. Os sorovares mais frequentes foram Patoc (35,71%), Butembo (32,14%) e Sentot (14,30%). O uso de pasto como volumoso (odds ratio =7,80; intervalo de confiança de 95% - IC95% 1,71-35,50; p=0,008) foi identificado como fator de risco. Sugere-se a necessidade de estudos acerca do isolamento do agente e da caracterização de sua patogenicidade, bem como se recomenda o controle de roedores em depósitos de ração e no ambiente.(AU)

RESUMEN

The aim of this work was to characterize the cattle raising in Paraíba State, Northeastern Brazil. The State was divided into three cattle production regions according to its mesoregions: production region 1 (Sertão mesoregion), production region 2 (Borborema mesoregion) and production region 3 (Agreste and Zona da Mata mesoregions). Overall, 689 rural properties from the three production regions were randomly selected. The variables used in the characterization were production system, farming system, type of milking, use of artificial insemination, milk cooling, number of lactating cows, daily milk production, herd size and number of bovine females > 24 months of age. It was found that most farms in Paraíba State are family or subsistence farms, predominantly mixed production, semi-intensive farming, with utilization of hand milking and natural mating, without use of milk cooling, low number of lactating cows and daily milk production. It were found differences and similarities among production regions so that it is suggested that such aspects must be taking into account in livestock development public policy planning, as well as in the implementation of disease control strategies.(AU)

O objetivo do presente trabalho foi caracterizar a pecuária bovina no Estado da Paraíba, Nordeste do Brasil. O Estado da Paraíba foi dividido em três circuitos produtores de bovinos, levando-se em consideração as suas mesorregiões: circuito produtor 1 (mesorregião do Sertão), circuito produtor 2 (mesorregião da Borborema) e circuito produtor 3 (mesorregiões do Agreste e Zona da Mata). No total, foram selecionadas aleatoriamente 689 propriedades rurais distribuídas nos três circuitos produtores. As variáveis utilizadas na caracterização foram tipo de exploração, tipo de criação, tipo de ordenha, uso de inseminação artificial, resfriamento do leite, número de vacas em lactação, produção diária de leite, tamanho do rebanho e número de fêmeas bovinas com idade > 24 meses em relação ao total de bovinos. Pelos resultados obtidos constatou-se que a maioria das explorações pecuárias paraibanas é familiar ou de subsistência, com predominância de exploração mista, criação semi-confinada, com utilização de ordenha manual e monta natural, sem emprego de resfriamento do leite produzido, com baixo número de vacas em lactação e baixa produtividade diária de leite. Foram encontradas diferenças e semelhanças entre os circuitos produtores, de maneira que se sugere que tais aspectos sejam levados em consideração quando do planejamento de políticas de desenvolvimento pecuário, bem como na implementação de ações de controle de doenças.(AU)

RESUMEN

This report aims to describe a case of colic intussusception, type one, in a crossbreed cow. The clinical findings included dehydration, anorexia, apathy and ruminal hypomotility, besides a swelling in the right flank. On rectal palpation was not observed intestinal distension or presence of liquid, but the animal presented significant discomfort. The feces were blackened, with a putrid odor and presence of mucus. The complete blood count showed only a small increase in segmented neutrophils, without evidence of hemoconcentration or alterations in erythrocytes and leukocytes count. After clinical examination it was decided perform an exploratory laparotomy, where it was possible to observe the presence of fibrin and rupture of intestine. The corrective surgery was performed through bowel resection and subsequent anastomosis. Due to the severity of the case, the animal died one day after surgery. The diagnosis was based on clinical, laboratory and exploratory laparotomy.

Este relato teve como objetivo descrever um caso de intussuscepção do tipo cólico em um bovino, fêmea, adulto, sem raça definida. No exame clínico observou-se que o animal apresentava um quadro de desidratação, anorexia, apatia e hipomotilidade ruminal. Também foi possível observar um aumento de volume no flanco direito. Na palpação retal não se observou distensão das alças intestinais, presença de líquido, porém o animal demonstrou significativo desconforto. As fezes apresentaram-se enegrecidas, com odor pútrido e com presença de muco. No hemograma não foi observado hemoconcentração, nem alterações significativas nos eritrócitos e leucócitos, apenas um pequeno aumento nos neutrófilos segmentados. Diante disto, foi realizada uma laparotomia exploratória, onde foi possível observar presença de fibrina e rompimento de alças, depois de identificado o caso foi realizado uma enterectomia, seguida de anastomose. Devido à gravidade e evolução do quadro o bovino não resistiu vindo a óbito no dia posterior a cirurgia. O diagnóstico se baseou nos achados clínicos, laboratoriais e na laparotomia exploratória.

Este relato teve como objetivo descrever um caso de intussuscepção do tipo cólico em um bovino, fêmea, adulto, sem raça definida. No exame clínico observou-se que o animal apresentava um quadro de desidratação, anorexia, apatia e hipomotilidade ruminal. Também foi possível observar um aumento de volume no flanco direito. Na palpação retal não se observou distensão das alças intestinais, presença de líquido, porém o animal demonstrou significativo desconforto. As fezes apresentaram-se enegrecidas, com odor pútrido e com presença de muco. No hemograma não foi observado hemoconcentração, nem alterações significativas nos eritrócitos e leucócitos, apenas um pequeno aumento nos neutrófilos segmentados. Diante disto, foi realizada uma laparotomia exploratória, onde foi possível observar presença de fibrina e rompimento de alças, depois de identificado o caso foi realizado uma enterectomia, seguida de anastomose. Devido à gravidade e evolução do quadro o bovino não resistiu vindo a óbito no dia posterior a cirurgia. O diagnóstico se baseou nos achados clínicos, laboratoriais e na laparotomia exploratória.(AU)
