Indian Journal of Medical Microbiology. 2011 Apr-June; 29(2): 165-168.http://imsear.searo.who.int/handle/123456789/143802The present study was conducted to correlate the biotypes of Gardnerella vaginalis strains isolated from cases of bacterial vaginosis and their virulence factors. Thirty-two strains of G. vaginalis isolated from cases of bacterial vaginosis were biotyped. Adherence to vaginal epithelial cells, biofilm production, surface hydrophobicity, phospholipase C and protease activity were tested on these isolates. Biotype 1 was the most prevalent (8; 25%), followed by biotype 2 (7; 21.9%) and biotypes 5 and 8 (5; 15.6%). We did not find any statistical correlation between G. vaginalis biotypes and its virulence factors. Virulence factors expressed by G. vaginalis were not associated with a single biotype.enBacterial vaginosisbiotypesvirulence factorsAdultBacterial AdhesionBacterial Typing TechniquesBiofilms --growth & developmentEpithelial Cells --microbiologyFemaleGardnerella vaginalis --chemistryGardnerella vaginalis --classificationGardnerella vaginalis --isolation & purificationGardnerella vaginalis --pathogenicityHumansHydrophobic and Hydrophilic InteractionsPeptide Hydrolases --metabolismType C Phospholipases --metabolismVaginosis, Bacterial --microbiologyVirulence Factors --geneticsArticle
