Bacteria STI's associated with vaginal alkalinity

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

I don't know how "Academic" this link is, but it would suggest that BV and trichomonas will cas alkaline shift. Candida can in some cases result alkaline shift, but not normally.

Arrow Only candida not associated

Only candidal infection is not associated with alkalinity the other two are associated.

BV is specially associated with it because it's a matter of altered flora rather than just an infection.
