STUDIES ON LEPTOSPIROSIS IN THAILAND, WITH SPECIAL REFERENCE TO THE EPIDEMIOLOGY, PATHOLOGY AND CLINICAL ASPECTS, AND ITS RELATION TO THE ANIMAL RESERVOIR HOSTS
Abstract
Epidemiological study on leptospirosis in Thailand by surveying leptospiral antibodies among the general population in 71 provinces revealed positive agglutination reactions of 22-35%. The high incidences were mostly found in South Thailand. The common serotypes were L. grippotyphosa, L. icterohemorrhagiae and L. bataviae. Most cases were farmers; the ratio of males to females was 3:2. Examinations for laboratory diagnosis of leptospirosis were made in the past twelve months in about 1400 patients of various hospitals throughout Thailand. The results showed the L bataviae was the most prevalent serotype in Bangkok, while L. grippotyphosa was the common one in the provincial areas. The clinical and laboratory features of 34 cases of leptosphirosis, most of which caused by L. bataviae, were also analysed. About 15% of cases of pyrexia of unknown origin in a municipality hospital of Bangkok were found to suffer from leptospirosis, and L. bataviae and L. canicola were the common serotypes in volved. The results of macroscopic screening tests in human leptospirosis were satisfactory, while in animal leptospirosis only the specimens with high titres gave some positive reactions. L. biflexa No. 138 had a promising antigenic property reacted to L. bataviae antisera.
