Abstract
Wild birds are important in the epidemiology of toxoplasmosis because they can serve as reservoir hosts, and vectors of zoonotic pathogens including Toxoplasma gondii. Canada goose (Branta canadensis) is the most widespread geese in North America. Little is known concerning T. gondii infection in both migratory, and local resident populations of Canada geese. Here, we evaluated the seroprevalence, isolation, and genetic characterization of viable T. gondii isolates from a migratory population of Canada geese. Antibodies against T. gondii were detected in 12 of 169 Canada geese using the modified agglutination test (MAT, cutoff 1:25). The hearts of 12 seropositive geese were bioassayed in mice for isolation of T. gondii. Viable parasites were isolated from eight. One isolate was obtained from a seropositive goose by both bioassays in mice, and in a cat; the cat fed infected heart excreted T. gondii oocysts. Additionally, one isolate was obtained from a pool of four seronegative (<1:25) geese by bioassay in a cat. The T. gondii isolates were further propagated in cell culture, and DNA extracted from cell culture-derived tachyzoites were characterized using 10 polymerase chain reaction-restriction fragment length polymorphism (PCR...Continue Reading
