Interpretive summary: Toxoplasma gondii an obligate, single-celled, protozoan parasite continues to be a major zoonotic health concern in human and veterinary medicine because it is capable of infecting any warm-blooded vertebrate intermediate host. As the definitive host, cats are fundamental in the epidemiology of toxoplasmosis. Millions of oocysts can be excreted in the feces of a single cat and oocysts can survive outdoors for months. Viable T. gondii has been isolated from feces of naturally infected dogs, indicating that the dog can act as a mechanical vector following the ingestion of infected cat feces. Humans can also become infected by petting dogs that have rolled in cat feces. Because of their close association with humans dogs are considered good sentinel for environmental contamination with this parasite. In the present study authors found that 67% of 101 dogs from Veracruz State, Mexico had antibodies to T. gondii, indicating a very high level of environmental contamination with t. gondii. This study should be of interest veterinarians and public health workers.
