Abstract
Leptospirosis has emerged as an important infectious disease in Sri Lanka and little information is available on circulating leptospiral species and serogroups in this country. Therefore, we studied circulating leptospiral species and serogroups in patients with acute febrile illness using polymerase chain reaction and the microscopic agglutination test, respectively. Anti-leptospiral antibodies were detected in 26 of 107 serum samples studied (24.3%). The predominant reacting serogroups were Sejroe (9/26, 34.6%) and Icterohaemorrhagiae (5/26, 19.2%). Leptospiral DNA was detected in 3 of the 107 serum samples. The deduced leptospiral species were Leptospira interrogans and L. kirschneri (2 and 1 samples, respectively). These results confirm the existence of a wide array of leptospiral species and serogroups in Sri Lanka and would help to thoroughly elucidate the epidemiology of leptospirosis in this country.
TL;DRThe results confirm the existence of a wide array of leptospiral species and serogroups in Sri Lanka and would help to thoroughly elucidate the epidemiology ofLeptospirosis in this country. (Semantic Scholar)
