Prevalence of antibodies to Toxoplasm gondii was studied using the latex agglutination (LA) method, followed by sucrose density gradient centrifugation (SDGC) method on the small Indian mongoose (Herpestes auropunctatus), which inhabits Amami-Oshima Island. Of the 362 samples, 38 (10.5%) revealed positive. Single or double peaks in the 7–8 and/or 12–14 fraction to LA titer by SDGC indicated the early stage of T. gondii infection. It is suggested that domestic/feral cats play an important role for spreading this zoonotic pathogen to the mongoose as well as other species that are endemic to this island. Future studies are warranted to prevent the transmission of T. gondii among cats and wild animals in order to maintain the ecosystem health.

On Amami Oshima Island, free-ranging and feral cats are harmful to wildlife populations. In this study, the seroprevalence of Toxoplasma gondii in these cats was examined using a newly developed Gaussia luciferase immunoprecipitation system assay. Of 1,363 cats, 123 cats (9.0%) was positive for T. gondii. The prevalence was significantly different in different areas; among cats in the rural area, where many wild animals live, including endangered species, T. gondii infection was more prevalent than in the urban area of the island. This finding indicates a possible risk to wildlife of infection from free-ranging and feral cats. Therefore, management of cats is important for wildlife conservation.
