Abstract
The prevalence of Toxoplasma gondii infection in free-ranging cats on
Tokunoshima Island was assessed by testing 125 serum samples using anti-T.
gondii IgG indirect enzyme-linked immunosorbent assay. The overall
seropositivity rate was 47.2% (59/125). Seropositivity rates in cats with body weight
>2.0 kg (57.4%) were significantly higher than in those with body weight ≤2.0 kg
(12.5%, P<0.01). Analysis of the number of seropositive cats by
settlement revealed the presence of possibly-infected cats in 17 of 23 settlements,
indicating the widespread prevalence of T. gondii on the island. This is
the first study to show the seroprevalence of T. gondii in free-ranging
cats on Tokunoshima Island. The information revealed in this paper will help to prevent
the transmission of T. gondii among cats and also in both wild and
domestic animals and humans on the island.
