Abstract
An analysis of intracellular and extracellular leptospiral enzymes was made by use of starch-gel electrophoresis with natural and synthetic substrates. Of 37 serotypes examined for extracellular exterase, all had activity of varying mobility and degree. All extracellular preparations were negative for catalase, phosphatase, and naphthylamidase. Intracellularly, five serotypes were examined, including Leptospira biflexa Patoc I, L. biflexa Waz, L. canicola Moulton, L. icterohaemorrhagiae RGA, and L. pomona S91. Among the enzymes detected by this electrophoretic technique were transaminase and catalase, confirming the results of previous investigators. Further, other enzymes heretofore unreported have been detected. These include esterases, phosphatases, lactic, malic, glutamic, succinic, α-glycerophosphate, and 6-phosphogluconic dehydrogenases, and a naphthylamidase. The presence of these enzymes suggests the existence of tricarboxylic acid, glycolytic, and pentose-related pathways in Leptospira. In addition, enzyme patterns show promise in leptospiral classification.
