Abstract
HERVE-CLAUDE, Luis et al. Seroprevalence and risk factors for Neospora caninum in small dairy farms in central Chile. Rev.MVZ Cordoba [online]. 2017, vol.22, n.1, pp.5666-5673. ISSN 0122-0268. https://doi.org/10.21897/rmvz.926.
Objective.
To provide information about seroprevalence and risk factors of Neospora caninum infection in bovines of central Chile.
Material and Methods.
The study population are small dairy farms that are part of a Government Technical Support Service (SAT) in the O´Higgins region in central Chile. Sera samples were collected from milking cows and analyzed by a commercial ELISA kit. Additionally, a questionnaire was applied to farmers to identify risk factors through logistic regression.
Results.
The farm level prevalence was found to be 67%, and within farms seroprevalence 55%. Abortion history (p= 0.037, OR=5.09), dogs feed source (p= 0.0429, OR=6), cattle drinking water source (p=0.034, OR=4.5) and abortions management (p=0.017, OR=7.43) were found as significant risk factors for infection.
Conclusion.
There is a high N. caninum seroprevalence in small SAT´s dairy farms in O´Higgins region. These results highlight the need of improving N. caninum surveillance, and the development of preventive measures to avoid losses related with this disease.
