The yogurt was topically applied overnight with a pad to make sure it stayed in the area. We would have thought there would be some noticeable improvement by morning but no.
I've had experience with a GF (before wife) that was taking a lot of antibiotics that killed all the good bacteria in the mouth which was pretty uncomfortable. The Dr. told her to eat some yogurt and she started getting better right away so it did work that time. Same Dannon plain yogurt. So I have no idea why it would have worked one place and not the other. I'll have to leave the speculation to someone with some medical training to try and make sense of it.

Why it worked w/ the mouth instead of the vagina:
The yogurt was placed
inside the mouth; therefore, the action took place directly @ the site. Placing the yogurt on the outside of the vagina (even if it was the "right" yogurt) would never have worked because the yogurt never made it
to the site. (Think Monostat: to work, it must be inserted).
I did a little research on the use of yogurt to treat yeast:
Eating the yogurt to treat a vaginal yeast infection: no way would this work if the yogurt does not contain acidophilus (read the label!). Your stomach would simply digest the yogurt and all of it's elements. (Acidophilus can survive the digestive process.) BTW - sugar cancels out the effects of acidophilus. If you absolutely need a sweetener - use honey. Avoid sugar of any type while you have a yeast infection.
If you can get ahold of yogurt which contains acidophilus, you can eat it but that would take longer to work without applying the treatment
directly into the vagina: Dip a tampon into the yogurt and leave it there for an hour. Repeat every so often throughout the day for a few days until you're OK. All the while, keep eating the yogurt. The idea is to make your body inhospitable to the yeast.
You can also use acidophilus capsules - inserting one into the vagina every night.
Using yogurt with acidophilus may be even better than doing monostat or diflucan if you're a frequent sufferer: Since yogurt is'n't an antifungal treatment, there is no risk that it will cause your yeast population to become drug resistant.
I also found this in several listings for bacterial infections: intake of large amounts of all the B vitamins: 100 mg. of B 1, B2, and B6; 299 mg B8 as well as pantothenic acid.
