- This is the first study of seroprevalence of T. gondii in wild birds in Taiwan.
- Antibodies to T. gondii were detected in several endemic avian species in Taiwan.
- The pathogen is widespread in Taiwan from urban to the wild.
- Further investigation is needed for the impaction of the pathogen to wild birds.
Toxoplasma gondii is a zoonotic protozoon which is well known for infecting humans and wild animals. In the present study, antibodies to T. gondii were evaluated in 394 wild birds, belonging to 37 species, from 15 different administrative regions in Taiwan. Using modified agglutination test (MAT), the overall seroprevalence of infection was 23.35% (CI 95%Â =Â 19.17%-27.53%). Antibodies were detected in birds of prey (25.73%, CI 95%Â =Â 19.76%-31.70%), birds living in freshwater or marine systems (34.29%, CI 95%Â =Â 18.56%-50.01%) and ground-feeding birds (18.12%, CI 95%Â =Â 11.94%-24.31%). Adult birds showed higher seroprevalence than that in juvenile birds, and the presence of clinical abnormalities was associated with T. gondii seropositivity. The results showed that this pathogen has spread widely in Taiwan. This suggests the zoonotic potential of the disease, with transmission from urban to rural regions, and from terrestrial to aquatic systems. The pathogenicity of T. gondii infection in wild birds in Taiwan needs further investigation. This is the first study of the seroprevalence of T. gondii in wild birds in Taiwan.
