Differentiation of Leptospira interrogans isolates by IS1500 hybridization and PCR assays.

Abstract excerpt

Genetic variability among Leptospira interrogans (sensu stricto) serovars was assessed by Southern blot hybridization and PCR analyses. The experiments used probes directed to sequences in a recently described insertion element, IS1500. Hybridization analysis showed that IS1500 was present on polymorphic fragments and that differences in these patterns could be used to identify serovars. Hybridization analysis...
