Neospora caninum causes abortion in cattle and neuromuscular disease in dogs, world wide. Cattle become infected by ingesting oocysts voided by dogs. The aim of this study was to estimate the seroprevalence of Neospora caninum in two populations of dogs (stray and owned) in Grenada, West Indies. Sera were collected from 625 dogs from all parishes in Grenada. Three hundred and sixty eight dogs were stray, while 257 dogs were owned. Sera were tested for the presence of antibodies against N. caninum using an indirect enzyme linked immunosorbant assay (ELISA) IDvet, France. Antibodies to N. caninum were found in 6 (1.6%) (95% confidence interval (CI): 0.32% to 2.88%) of the stray dogs and in 3 (1.2%, 95% CI: 0.13% to 2.53%) of the owned dogs. Seroprevalence did not differ significantly between the two populations (p=0.74) and between the males and females (p=1). These results suggest that the prevalence of N. caninum infection in dogs in Grenada is low.
