title: Seroprevalence of antibodies to Neospora caninum in Bos javanicus ('Bali cattle') from Indonesia.
abstract: A cross-sectional survey was performed to obtain first information on the presence of Neospora caninum infection in Bos javanicus ('Bali cattle'), the predominant beef cattle in the Eastern Islands of Indonesia. Serum samples were collected from 438 Bali cattle of two age classes (<2 years, >2 years) and both genders at three slaughterhouses in the Bali island, and examined for N. caninum-specific antibodies using native NcSRS2 (p38 antigen) as an ELISA antigen. The estimated overall seroprevalence of antibodies was 5.5% (95% CI: 3.5-8.0%). The seroprevalence was not significantly associated with age class or gender of the animals. The results give first serological evidence for the presence of natural N. caninum infection in Bos javanicus and indicate its occurrence in Indonesia.
