Electrophoresis of water-insoluble leptospiral proteins and the taxonomy of Leptospira.

The cellular debris obtained after lysis of Leptospira were solubilized by sodium dodecyl sulfate and studied by polyacrylamide electrophoresis, comparing the molecular weight and relative concentration of the protein bands. The percentage similarity of 30 characteristic bands from 21 Leptospira strains, belonging to the main pathogenic and some saprophytic serogroups, was calculated; A partial matching of the derived dendrogram with the other classifications was observed.
