Abstract
CRUZ-ESTUPINAN, S. et al. Serological diagnosis of Neospora caninum in cows of Tuta, Boyacá. Rev. Med. Vet. Zoot. [online]. 2019, vol.66, n.3, pp.197-207. ISSN 0120-2952. https://doi.org/10.15446/rfmvz.v66n3.84256.
Neospora caninum is a protozoan parasite of the phylum Apicomplexa, and has been recognized as a major cause of abortion and reproductive failure in cattle in the world, Although in Colombia there are some studies on the seroprevalence of this disease, even so the information remains limited.
Objective:
the aim of this study was to establish the seroprevalence of N. caninum in dairy cows of Tuta, (Boyacá, Colombia).
Materials and methods:
375 animals were sampled. The samples were processed under indirect ELISA technique, a statistical analysis was performed with the chi-square association independence test to determine if there was a relationship between the presence of antibodies against N. caninum and the different reproductive variables.
Results:
it was observed that 52% of the individuals were positive for antibodies against N. caninum. the only reproductive variable that presented a statistical relationship with the presence of the protozoan was repetition of estrus, there was no relationship between age and breed of the cattle and the presentation of N.caninum.
Conclusions:
the seroprevalence is high if they if you keep in mind the seroprevalence data previously reported in other regions of the country, however, these results do not demonstrate the presence of disease in the animals analyzed, but the antigenic evidence, which implies that at some point life they became infected with the agent and promoted the formation of specific antibodies.
Keywords : N. caninum; Seroprevalence; Indirect Elisa (Source DeSC).
