[Methodological aspects of serological diagnosis in leptospirosis].
The results of serological study for leptospirosis of 515 blood serum specimens from patients coming to different clinics of the Republic of Bangladesh, are presented. The sera were tested in microagglutination test. To exclude intergroup reactions and to enhance reliability of results, immunoglobulin classes were determined with the use of cysteine as a reducing agent and immunoabsorption test. In 51 patients (9.9%) antileptospiral antibodies were detected in titers from 1:20 to 1:1600 against pathogenic leptospires of different serological groups.
