Detection of Leptospiral DNA from Field Rodents by PCR

ABSTRACT

Leptospirosis has been one of important epidemic diseases in Korea since 1984. Wild rodents, mostly Apodemus agrarius, served the important source of infection especially in harvest season in rural areas of Korea. Prevalence of Leptospira spp. infection in field rodents were investigated by detecting leptospiral DNA from rodent kidney. Among 108 rodents collected from various areas in 1998, leptospiral DNA were detected from 7 rodents (6.48%). Among 104 rodents, Apodemus agrarius, captured from Yeonchon and Paju area in 2001 and 2002, leptospiral DNA were detected from 6 rodents (5.76%). No leptospiral DNA was detected from 23 rodonts (Apodemus peninsulae 16, Apodemus agrarius 2 and Eothenomys regulus 5) captured in Odae mountain area in 1998.
