You're right it would be useful to identify the bacteria just so you know what you're dealing with but if you've been using Antibiotics , contraceptive pill, etc then you've lowered your immune system too. The steps I'm trying to take include coming off all drugs, chemical soaps, cosmetics etc, eating as much organic produce as possible, doing the cleanses, taking some antifungals and replacing with good bacteria (Nature Biotics at the moment). Although it would be nice to know which bacteria it is (I'm trying to find out), I've heard that it's all about boosting your immune system and feeding your body what it wants. That is why some people get catch a cold and others don't, it's the same thing, bacteria and whether their host is weak enough to invade...
Sorry just my thoughts, I know it's a job in itself boosting a suppressed immune system.
