Abstract

A survey was conducted to determine the distribution and prevalence of Toxoplasma gondii and Babesia microti infections in small mammals captured in Gyeonggi and Gangwon Provinces, Republic of Korea (ROK). The serological prevalence of T. gondii (ELISA) and B. microti (IFAT) was 2.3% (15/667) and 2.1% (14/667), respectively. DNA extracts from small mammal heart tissues were screened by PCR for T. gondii and B. microti targeting regions of the GRA5 gene and the 18S rRNA and β-tubulin genes, respectively. Only 0.17% (1/578) of Apodemus agrarius was positive of T. gondii by PCR, while 0.52% (3/578) was positive of B. microti. All other small mammal species [Micromys minutus (16), Mus musculus (3), Myodes regulus (22), Microtus fortis (6), and Crocidura lasiura (42)] were negative for both T. gondii and B. microti. Based on sequence polymorphism and phylogenetic analysis, T. gondii closely aligned with Type I, a highly virulent strain, while B. microti positive samples closely aligned with US-type B. microti and others observed in the ROK, Russia, and Japan. These results indicate that A. agrarius is a reservoir for both T. gondii and B. microti in the ROK.
