###Human: Can HIV be transmitted through oral sex? ###Assistant: Hi. Frequency of sex has nothing to do with E. coli bacteria (Escherichia coli). Prostatitis is very resistant to treat, so it is not necessary that if you have taken treatment, it will not recur. Sometimes, you have to take 4 to 6 months of treatment for prostatitis. This is the main reason why you are still having the pain. Semen and culture usually do not cover all STDs (sexually transmitted diseases) and lower abdominal pain is a non-specific symptom and can be attributed to prostatitis. Yes, HIV (human immunodeficiency virus) can be transmitted through oral sex. So if you know the person, it is better to get her tested because if she is not HIV positive, then you need no testing. Nevertheless, you can go for HIV 1 and 2 antibody test by ELISA (enzyme-linked immunosorbent assay) method and HIV RT-PCR (reverse transcription polymerase chain reaction). I hope the above information is useful to you.
