Welcome to the HIV forum.
I will assume your yeast infection was indeed yeast, and not another skin fungus, like jock itch. Yeasts can be shared between sex partners, even though yeast is not considered an STD.
1) Although some genital infections (e.g., herpes, syphilis, chlamydia, gonorrhea) increase the likelihood of HIV transmission, yeasts are not known to do so.
2) The acinetobacter probably is irrelevant. It is a normal bacteria on the skin and in the vagina and not surprising that it may show up in a male genital tract. The question is why it was discovered at all. In my clinic, we would rarely do any test that would show it.
Statistically, the chance your female partner had HIV is low. And even if she was at particularly high risk (e.g., a commercial sex worker) or even known to have HIV, the chance you were infected was low, somewhere on the order of 1 chance in 2,000. But since you're nervous about it, have an HIV test. You can expect it to be negative.
Good luck-- HHH, MD
Thanks so much for your knowledge-- this forum is incredible, and fast!
I had a urethral swab/culture in Nicaragua which detected both the candida and acinetobacter.
Tomorrow is my 7 week and 6 day test (95% sure right?)-- and I'll follow up after 3 months for sure.
For your information-- not a commercial sex worker, but quite possibly highly promiscuous. It was in a very low incidence country, but high incidence city within that country. I know it's silly to be calculating odds, but it really is reassuring-- I'll take 1 in 2000 con gusto (with pleasure) over what I thought my chances were-- like 50/50. I'll let you know when the test comes back.
Thanks again for all your help.
