ABSTRACT

Abstract Neosporosis is one of the major parasitic diseases that causes reproductive problems, making it a limitation for optimal efficiency in livestock. The aim of the present study was to conduct a seroepidemiological survey for bubaline neosporosis and to analyse associated factors associated with N. caninum infection in female water buffaloes in the State of Pernambuco, northeast Brazil. The prevalence of N. caninum infection in the bubaline herds examined was 35.4% (122/345; 95% CI: 30.4%-40.7%), at least 1 Neospora-positive animal was found in each farm. Associated factors for N. caninum infection identified in this study were exclusive pasture feeding (OR: 5.91, p <0.001) and purchase of animals of free fair and from reputable sellers (OR: 1.85; p =0.045). In this survey, we document the occurrence of neosporosis in female water buffaloes. Associated factors should be controlled in order to reduce the risk of N. caninum infection in these herds.


Resumo A neosporose é uma das principais doenças parasitárias que causa problemas reprodutivos, torna-se possível limitar para a máxima eficiência na pecuária. Objetivou-se com este estudo realizar um inquérito soroepidemiológico e analisar os fatores associados à infecção por N. caninum em fêmeas bubalinas no estado de Pernambuco, Brasil. Observou-se uma prevalência de 35,4% (122/345; IC 95%: 30,4%-40,7%) para infecção por N. caninum e 100% das propriedades possuíam ao menos um animal positivo. Os fatores associados à infecção por N. caninum neste estudo foram alimentação exclusiva a pasto (OR: 5,91; p<0,001) e aquisição de animais de feiras livres e criadores conhecidos (OR: 1,85; p=0,045). Registra-se a ocorrência da infecção por N. caninum em fêmeas bubalinas e os fatores associados que precisam ser corrigidos para reduzir o risco de infecção nesses rebanhos.

ABSTRACT

ABSTRACT The objective of this study was to evaluate the occurrence of anti-Leptospira spp. antibodies in female buffalo in the state of Pernambuco. A total of 123 female buffalo blood samples were collected from five properties distributed in the state of Pernambuco. The microscopic agglutination test was used to study anti-Leptospira spp. antibodies. The occurrence of anti-Leptospira spp. antibodies was 28.5% (35/123; CI 20.7-37.3%) and on different properties, the occurrence ranged from 28.6% to 80.0%, with 100% of the properties showing animals with positive results. The serovars of the serogroup Sejroe with a higher incidence were Hardjoprajtino (CTG strain, 49.1%) and Hardjo (Prajtino genotype, 43.2%), followed by serogroup Grippotyphosa with the Grippotyphosa serovar (3.9%), serogroup Pomona with the Pomona serovar (1.9%), and the Icterohaemorrhagiae serovar Copenhageni (1.9%). This was the first record of the occurrence of anti-Lepstospira spp. antibodies in female buffalo in the state of Pernambuco. Control measures are necessary to prevent health and economic losses, given that the agent involved affects animal reproduction, triggering drops in conception rates or even clinical cases of abortion.

ABSTRACT

Objetivou-se com este estudo determinar a ocorrência e os fatores de risco associados à infecção por Campylobacter spp. em criações de ovinos no estado de Pernambuco, Brasil. Foram coletadas 421 amostras fecais de ovinos procedentes de 20 rebanhos para o isolamento de Campylobacter spp. As espécies Campylobacter fetus subsp. fetus e Campylobacter jejuni foram identificadas por Reação em Cadeia da Polimerase (PCR). Para análise dos fatores de risco foi realizada uma análise univariada e posteriormente regressão logística a partir de questionário com perguntas objetivas sobre o manejo higiênico-sanitário e reprodutivo. A ocorrência para Campylobacter spp. foi de 4,5% (19/421; I.C. 2,8% - 7,1%). Das 19 amostras positivas no cultivo, oito (1,9%; I.C. 0,9% - 3,9%) foram classificadas como C. fetus subsp. fetus e sete (1,7%; I.C. 0,7% - 3,6%) como C. jejuni, com co-infecção em quatro amostras (0,95%). O número de focos identificados foi de 35,0% (7/20) das criações de ovinos que apresentavam pelo menos um animal positivo. Na análise de regressão logística não foi identificada nenhuma das variáveis como fator de risco. Este é o primeiro registro da infecção por Campylobacter spp. em rebanhos ovinos no Nordeste do Brasil, concluindo-se que a infecção ocorre nesses rebanhos. Dessa forma, se faz necessário à implementação de medidas de controle e prevenção, para impedir a propagação do agente entre as criações, evitando prejuízos para ovinocultura e riscos para saúde pública, uma vez que a campilobacteriose é considerada uma zoonose emergente.(AU)


The objective of this study was to determine the occurrence and risk factors associated with Campylobacter spp. infection in sheep in the State of Pernambuco, Brazil. A total of 421 fecal samples were collected from 20 herds for the isolation of Campylobacter spp. The species Campylobacter fetus and Campylobacter jejuni were identified by Polymerase Chain Reaction (PCR). To analyze the risk factors, logistic regression was conducted through a questionnaire about the hygienic-sanitary and reproductive management. The occurrence of Campylobacter spp. was 4.5% (19/421; C.I. 2.8 to 7.1%). Of the 19 positive samples isolated, eight (1.9% CI 0.9 to 3.9%) were classified as C. fetus subsp. fetus and seven (1.7% CI 0.7 to 3.5%) as C. jejuni, with co-infection in four samples (0.95%). The number of identified focuses was 35.0% (7/20) of the sheep herds that had at least one positive animal. The logistic regression analysis did not identify any of the variables as a risk factor. This appears to be the first report of infection with Campylobacter spp. in sheep herds in northeastern Brazil. Thus it is necessary to implement measures for control and prevention avoid damage to sheep production and risk to public health, since campylobacteriosis is considered an emerging zoonosis.(AU)
