Serological evidence of Neospora caninum infections in beef bulls in six counties of the Corrientes province, Argentina.
The purpose of the present work was to identify Neospora caninum infections in beef bulls belonging to 19 herds from six counties located in the Corrientes province, Argentina. The presence of antibodies to N. caninum was evaluated in 305 serum samples of bulls (Bos taurus and Bos indicus). Age and breed were recorded. An indirect fluorescent antibody test was used to determine specific antibodies. The number of bulls with natural Neospora-infection was 15 of 305 (4.9%). No association between serologic status and breed (odds ratio (OR), 0.53; 95% CI, 0.18-1.53) was found. Neospora-infected beef bulls were identified in the present work. The bull role in bovine neosporosis and the risk of horizontal transmission for cows should be investigated.
