I had protected vaginal and unprotected oral (both ways) about 6 months ago - about 3 months before her symptoms started.  Even though I tested fine I'm worried because I know the urine test would catch anything oral, and I was also on antibiotics during that time for what was a strept infection and this was before I was tested.

So my questions are:

Can the BV test be misread as BV when it is really an STD?

Is it possible I had something oral that I passed on to her?

If I tested now would it show up?

Welcome to the Forum.  Your questions deals with an all too common and frustrating topic.  A few background comments first which will help before I address your specific questions.  Bacterial vaginosis is the most common cause of vaginal discharge in women and how it related to sexual activity is a topic of ongoing research.  BV is rare in persons who have never had sex (but it does occur) and it is unclear whether treatment of partners is beneficial or not.  Further, the treatment of BV is not very good with over half of women who are treated having recurrent symptoms within 3-6 months of treatment.  We have numerous patients who suffer with BV.

In contrast, most STIs in women are actually asymptomatic and only a minority of infections cause symptoms of the sort you describe.

Finally, the encounter you describe above was condom protected and condoms do protect from BV. 

With this background, let's go to your specific questions: 

Let me clarify a couple of questions.  

I do not believe they tested her for STIs. So my concern is whether the test for BV could be read as positive for what is really an STI in the absence of a specific STI test? The info online about this test is very confusing. 

My concern was not about passing her BV but rather that I had passed her something I was carry orally like gonorrhea or chlamydia?

Since she isn’t responding to the antibiotics for bv it makes me worried that it is really something else. 

I must point out that, unfortunately, unless she asked, it is all too possible that she was tested for STIs and not told.  Sadly, this is rather common.  In addition, there are several tests for BV.  I presume you do not know what test was performed.  Further, BV can co-exist with STIs at the same time.  Thus, unless you know far more detail about her medical records and her interactions with her doctors than most spouses do, there is no way to know.  Symptoms are NOT helpful. Further, I must point out that if you are going to the internet for information, you are quite likely to be misled by incorrect information or statements made without an appropriate context.  Much of what we do on this site is to try to correct misperceptions which arise from our clients internet searches. 

Regarding your concern (guilt) over having possibly passed an STI like gonorrhea or chlamydia to her, as I said, when they are transmitted through cunnilingus these infections are most often asymptomatic. 

As I also said earlier, management of BV is not very satisfactory.  It often requires trial and error.  The likelihood that you had an oral STI, passed it on to your wife through oral sex, and that this is the source of her persistent/recurrent symptoms is very, very low.  EWH

One final question, how would a hysterectomy impact her ability to contract and demonstrate symptoms for BV and STIs? (I suppose that is more than one questions; just let me know if I should post as a separate question).

Bacterial vaginosis is a syndrome which involves the vagina and not the uterus. Thus women who have had hysterectomies can still get BV.  OTOH, the major complications of lower genital tract STIs in women arise in the uterus and tubes and are not a concern for women with hysterectomies.

I hope my comments have been helpful.  Our Forum provides up to three replies to client questions.  This is the 3rd reply. Thus this thread will be closed in a few hours without further answers.  Take care.  Please don't worry.  EWH
