Rats are considered the principal maintenance hosts of . The objectives of this study were isolation and identification of serovars circulating among urban rat populations in Kuala Lumpur. Three hundred urban rats (73% and 27% ) from three different sites were trapped. Twenty cultures were positive for using dark-field microscopy. was the dominant carrier (70%). Polymerase chain reaction (PCR) confirmed that all isolates were pathogenic species. Two serogroups, Javanica and Bataviae, were identified using microscopic agglutination test (MAT). Pulsed-field gel electrophoresis (PFGE) identified two serovars in the urban rat populations: serovar Javanica (85%) and serovar Bataviae (15%). We conclude that these two serovars are the major serovars circulating among the urban rat populations in Kuala Lumpur. Despite the low infection rate reported, the high pathogenicity of these serovars raises concern of public health risks caused by rodent transmission of leptospirosis.
