A genital culture allows the organisms present in the vagina to grow to levels enabling identification.
The vagina is not sterile, but contains a mixture of aerobic, anaerobic, coliform, and skin bacteria, as well as a few fungi. Normally, these are in balance with no particular predominant organism.
Chlamydia and gonorrhea are usually not included in a genital culture as both require special media to detect.
Significant growth of any one organism usually indicates a clinical or subclinical infection. Common types of overgrowth include:
Yeast (candida albicans)
Streptococcus
Gardnerella
E. Coli
Proteus

Genital Culture
Normal Vaginal Flora
*These are general values taken from a variety of sources. The actual normal values may vary from lab to lab and from one type of testing protocol to another.
