The aim of this study was to describe bovine neosporosis in dairy cattle from the Sierra region, Ecuador. A case control study was performed on 841 dairy cattle from 5 dairy herds. The overall seroprevalence was 23.4% having significant association between abortion and seropositivity (p < .05). Additionally, 46 fetuses were recovered from a local slaughterhouse to evaluate the frequency of vertical transmission. Seventeen and 3 fetuses were positive by PCR and had compatible histopathological lesions, respectively. N. caninum infection must beconsidered as a relevant cause of reproductive losses in Ecuador.
