Incidence of Toxoplasma gondii in populations of wild birds in the Czech Republic.
The protozoan parasite Toxoplasma gondii was isolated from 193 individuals of 25 wild avian species, in a survey between 1981 and 90 in which 5880 individuals, comprising 76 species, were examined. The incidence of T. gondii was 18% in rooks (Corvus frugilegus), 12% in mallards (Anas platyrhynchos), 8% in common buzzards (Buteo buteo), 2% in pheasants (Phasianus colchicus) and 0.5% in house sparrows (Passer domesticus) and differed significantly in these species (X(2) test, P<0.001). In rooks, the cysts of T. gondii were found in the heart, brain, sex organs, skeletal muscle and liver.
