Neospora caninum seropositivity in cattle breeds in the South Fluminense Paraíba Valley, state of Rio de Janeiro
The hypothesis that there is a close association between cattle breeds and the frequency of infection by N. caninum is supported, as well as a high association between seropositivity and racial patterns was found. Expand
