One hundred and fifty human vaginal samples containing a diversity of pathogens or nonpathogens (Gardnerella vaginalis, Streptococcus sp., Staphylococcus sp., Candida albicans. Mycoplasma sp.) were examined for their content in lactobacilli of the Lactobacillus acidophilus complex. Although all samples contained lactobacilli, strains of the L. acidophilus complex were present in only twenty-nine cases. Isolates were further characterized and compared with type strains or reference strains in an attempt to differentiate by phenotypic means the genospecies of the L. acidophilus complex. Data regarding specific activities of beta-galactosidase (beta-gal) and of phospho-beta-galactosidase (P-beta-gal) provided no specific information at the species level within the L. acidophilus complex. DNA-relatedness differentiates this genospecies. Most lactobacilli isolated from the vaginal flora of symptomatic women were genotypically close to L. gasseri CIP 102991T by the technique of DNA/DNA hybridization.

D009005 Monosaccharides Single chain carbohydrates that are the most basic units of CARBOHYDRATES. They are typically colorless crystalline substances with a sweet taste and have the same general formula CnH2nOn. Monosaccharide,Simple Sugar,Simple Sugars,Sugar, Simple,Sugars, Simple
D009693 Nucleic Acid Hybridization Widely used technique which exploits the ability of complementary sequences in single-stranded DNAs or RNAs to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands.
