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.

Considering the scarcity of data and economic losses related to neosporosis in water buffaloes, the aim of the present study was to conduct a seroepidemiological survey for N. caninum infection in buffaloes and identify associated factors with positive serology in female water buffaloes in the State of Pernambuco, northeast Brazil
Summary
Water buffaloes (Bubalus bubalis) are rustic animals that are able to thrive in remote, difficult-to-access areas. Despite the tolerance of bubalines to difficult conditions and their resistance to a number of pathogens, they are still susceptible to some infectious and non-infectious diseases (ADLAKHA & SHARMA, 1992). The producer should meet certain sanitary requirements in order to achieve higher reproductive rates, ensuring herd health, In Brazil, buffaloes are bred for milk and beef, with a population of 1,970,941 million (IBGE, 2016).
