              Abstract 
 Aim:
              This serological survey was undertaken to estimate the 
              prevalence of Toxoplasma gondii in two populations of dogs 
              (stray and owned dogs) in Grenada. Dogs get infected with oocysts 
              voided from cats, definitive hosts of T. gondii. In dogs,
              T. gondii causes subclinical to clinical disease. Earlier 
              studies conducted in Grenada on a small population of owned dogs 
              showed evidence of exposure to T. gondii. 
              Materials and Methods: Antibodies to T. gondii were 
              determined in serum samples from 625 dogs (368 stray and 257 owned 
              dogs) from around all six parishes in Grenada, West Indies, using 
              an indirect enzyme linked immunosorbent assay.  
              Results: Antibodies to T. gondii were 
              found in 123 (33.4%; 95% confidence interval [CI]: 28.58-38.22%) 
              of stray dogs and in 64 (25%; 95% CI: 19.71-30.29%) of the owned 
              dogs. Seropositivity was higher in stray dogs than in pet dogs 
              (p=0.026). Whereas, there was no sex predisposition to 
              seropositivity in owned dogs (p=1.0), female stray dogs showed a 
              higher prevalence than male stray dogs (p=0.04). 
              Conclusion: These results support previous findings that T. 
              gondii is prevalent in Grenada. In this study, overall 
              seropositivity for T. gondii in dogs in Grenada is lower 
              than noted in 2008, but is still higher in stray dogs than in 
              owned dogs.  
              Keywords: dog, ELISA, Grenada, T. gondii.
