Growth Parameters Gardnerella vaginalis
PHYSIOLOGICAL  
Tropism Chemoorganotrophic
Oxygen Facultatively anaerobic having a fermentative type of metabolism
pH  
Temperature  
Requirements Fastidious in growth requirements
Products Acid but no gas is produced from a variety of carbohydrates including maltose and starch. Acetic acid is the major product of fermentation. Hippurate is hydrolyzed. Human blood, but not sheep blood, is hemolyzed
Enzymes Catalase- and oxidase-negative
Unique features  
ENVIRONMENTAL  
Habitat the human genital/urinary tract
Lifestyle  
Pathogenicity a major cause of bacterial "nonspecific' vaginitis.
