Identification of clinical isolates of Leptospira spp by pulsed field gel-electrophoresis and microscopic agglutination test.

Twenty-five clinical isolates of Leptospira spp were characterized by microscopic agglutination test (MAT) and pulsed field gel-electrophoresis (PFGE) in comparison with 23 reference Leptospira serovars and with the saprophytic L. biflexa serovar Patoc. PFGE DNA profiling was more specific and reliable than MAT.
