Serological analysis of human leptospirosis in the Philippines.

Leptospirosis in the Philippines is an underrepresented disease. To achieve an accurate means of serodiagnosis, we demonstrated antibodies to the prevalent Leptospira serovars in sera of 71 patients from three major hospitals in Manila by the microscopic agglutination test and Western blot analysis. Sera of 53 patients contained antibody against 8 serovars poi, tarassovi, manilae, pyrogenes, australis, grippotyphosa, javanica, and autumnalis.
