Serum samples from Asian elephants (Elephas maximus) in the Kanchanaburi, Chiang Mai and Lampang provinces of Thailand were tested using the microscopic agglutination test against 22 serovars of Leptospira interrogans. A titre of more than 1:100 was used as evidence of infection. In northern Thailand, the seroprevalence was 58 per cent and the prevalent serovars were Leptospira interrogans serovar Sejroe, Leptospira interrogans serovar Tarassovi, Leptospira interrogans serovar Ranarum and Leptospira interrogans serovar Shermani. In western Thailand, the seroprevalence was 57 per cent and the prevalent serovars were L Tarassovi, L Sejroe, L Ranarum, Leptospira interrogans serovar Bataviae and L Shermani. These results were similar to studies in domestic livestock and stray dogs in the Bangkok district. Among the elephants from Kanchanaburi there were significant associations between seropositivity and between the camp and between the prevalent serovars and the camp.
