Classification of Seven Leptospira Water Strains by Classical Methods and Identification of Three New Serovars

Six Leptospira strains isolated from surface water and one isolated from bovine urine were classified as members of Leptospira biflexa according to their antigenic and biological characteristics. Three new serovars were identified, for which we propose the names barbados, krefeldi, and neville. Serum sensitivity was tested for further biological characterization of the L. biflexa species.
