Genetic diversity within isolates of mutans streptococci recognized by an rRNA gene probe.

Journal of clinical microbiology - 1 Mar 1993

Saarela M, Alaluusua S, Takei T, Asikainen S

Abstract excerpt

A total of 79 clinical isolates of mutans streptococci and five laboratory strains representing serotypes c, d, e, f, and g were genotyped by a nonradioactive hybridization method with the rrnB rRNA operon of the Escherichia coli chromosome as a probe. The hybridization patterns of chromosomal DNA fragments obtained by digestion with restriction endonucleases HindIII, SmaI, and BamHI revealed genotypic...
