ESCALONA, Jorge J et al. Seropositivity to Neospora caninum in Dogs of Rural and Urban Areas of Yaracuy State, Venezuela. Rev. Fac. Cienc. Vet. [online]. 2013, vol.54, n.1, pp.29-34. ISSN 0258-6576.

An exploratory study was conducted to determine the Neospora caninum seropositivity and its association with the origin and sex in dogs from rural and urban areas of Yaracuy state, Venezuela. A total of 232 dogs were evaluated, 116 of which belonged to cattle production farms of Bolivar municipality and 116 were sampled to attend consultations in three private veterinary clinics in the city of San Felipe. The presence of antibodies against N. caninum was determined using indirect immunofluorescence serological technique, while the association of parasite seropositivity with origin and sex of the animals was determined by the odds ratio (OR). It was obtained a 12.93% overall positivity, being 20.69% for canines from rural areas and 5.17% for those from urban areas. Seropositivity was found significantly associated (P<0.05) to rural animal origin (OR=4.78), whereas no significant association was found (P>0.05) with sex. Evidences of the importance of dogs in the epidemiology of neosporosis in the study region were found.
