DNA relatedness among strains of Leptospira biflexa.
The slot blot method of DNA hybridization was used to study 38 strains of Leptospira biflexa belonging to 38 serovars. Fifteen of these serovars were placed into six groups. The remaining 23 serovars were generally too diverse to show significant DNA relatedness either to these groups or to one another. Serovar thracia was related to Group 5, but it was not included in this group because its percent relatedness was too low. We found that genetically related organisms were antigenically dissimilar. The absence of any significant genetic relationship between Leptonema illini and the Leptospira biflexa serovars tested supports the placement of the former species in a separate genus.
