Serological detection of Toxoplasma gondii in domestic dogs in the western region of Cuba.

We investigated the prevalence of IgG antibodies to Toxoplasma gondii in 176 dogs from Havana Province and Mayabeque Province, Cuba, by indirect enzyme-linked immunosorbent assay (iELISA). The overall prevalence was 72.72% (128/176). Dogs living on the cemented floor environment were significantly higher (p=0.01) in being positive for T. gondii. The high detection of antibodies to T. gondii parasite confirms the outstanding dogs in the West of the Cuban provinces, which is a potential hazard in the region, not only for dogs, but also for public health, considering it is a zoonosis of great importance.
