I'm having trouble nailing down exactly what STI's are associated with an alkaline shift (~pH of 4-5) in the vagina.

Bacterial vaginosis (caused by Gardnerella vaginalis overgrowth)
Trichomoniasis (caused by Trichomonas vaginalis infection)
Yeast infection (caused by Candida albicans colonization)

Of those three, I'm 99% sure that BV is associated with alkalinity and not entirely sure about the latter two. Review books don't mention it and the internet has conflicting / skeptical information.

Thanks all
