Use of Leptospira fainei serovar hurstbridge bacteria for diagnosing Leptospirosis

摘要

The present invention discloses an in vitro method for diagnosing a Leptospira infection in a biological sample of a subject, comprising a step of contacting said sample with bacterial cells of a serovar of the Leptospira fainei species, preferably bacterial cells of the Leptospira fainei serovar Hurstbridge, or an antigenic fraction of said bacterial cells. In a preferred embodiment, said Leptospira infection is not due to bacteria belonging to the serovar of the Leptospira fainei species used in the diagnostic method.
