Diagnóstico molecular de la infección gastrointestinal de neospora caninum en caninos

Abstract

Neosporosis in a parasitic infection caused by the protozoan Neospora caninum, the same that was first observed in 1984; it definitive host the mammals of the family of dogs, coyotes, dingos, etc., and their intermediary hosts are the bovine family, sheeps, goats, etc. This parasite is characterized by causing a long variety of neurological symptoms in infected animals, such as ataxia, muscular atrophy and muscle pain in dogs; while in cattle they can cause abortions, reabsorption or fetal mummification, among other pathologies. This research work is a quantitative cross - sectional type, since it was proposed with the purpose of knowing the sensitivity and specificity diagnostic of this parasite in dogs of the rural area of the canton Cuenca in the year 2017, for this it was done a test of feces through the diagnostic methods of Sheather's Sugar and CRP to 100 randomly chosen dogs, to later compare the results obtained by these two diagnostic techniques and present statistical analyzes using simple and composite tables, as well as statistical graphs. An incidence of 6 % (6 cases) was obtained as a result of the coproparasitary examination and an incidence of 1.06 % (1 case) using the PCR technique, however, there was no statistical relationship between these two variables, because the coproparasitary examin has a low sensitivity and specificity of in relation to the PCR test.
