title: [Gardnerella vaginalis biotypes: modification of a proposed system].
abstract: A modified scheme is proposed for biotyping Gardnerella vaginalis based on detection of hippurate hydrolysis, beta-galactosidase (ONPG) and lipase, and fermentation of arabinose, galactose and xylose. Thirty three biotypes were found among 140 strains from women with and without bacterial vaginosis (non-specific vaginitis). The distribution of biotypes were found to be significantly different, being more predominant the biotypes 1A; 5G; 7A; 7D and 7G in women with vaginosis and the biotypes 5G and 6H in women without vaginosis. These data suggest that some biotypes of Gardnerella vaginalis are associated with bacterial vaginosis.
