OCCURRENCE OF ANTIBODIES ANTI-NEOROSPORA CANINUM IN DAIRY AND BEEF CATTLE IN THE REGION OF PRESIDENTE PRUDENTE, SP, BRAZIL

ABSTRACT

Neospora caninum is considered one of the most important world wideagents that affect the bovine reproductive tract. In Brazil the initial studies of this infection were based on regional soroepidemiologic data. So, blood serum samples of 505 Nelore beef cattle and 408 of Holstein dairy cattle located in the region of Presidente Prudente, SP, Brazil were analysed using the immunoenzymatic ELISA test. The occurrence of antibodies anti-Neorospora caninum for dairy cattle was 35.54% (145/408) and 20.0% (101/505) for the beef cattle. The analysis of the results revealed evidence of N. caninum infection in the herds of this region, which was significatively higher in dairy cattle (p < 0.01).
