Human and animal leptospirosis caused by spp. belonging to serogroup Ballum has increased worldwide in the past decade. We report the isolation and serologic and molecular characterization of four serogroup Ballum isolates obtained from , and preliminary virulence studies. These isolates are useful for diagnosis of leptospirosis and for epidemiologic studies of its virulence and pathogenic mechanisms.
