I agree that strep has many ways of getting into the body and evading the immune system. Antibiotics would make the strep more resistant to further antibiotic treatment, due to natural selection and gene sharing etc. But I dont see how antibiotics can make bacteria become more virulent? Maybe by forcing them to grow elsewhere, or the antibiotics weakened the immune system allowing the bacteria to grow in other places. But I dont think this sort of thing is proven currently, and how severe or likely it is I dont know.
Often antibiotics need to be used several times for some conditions when a disease persists after an initial course of treatment. Studies show that on second round treatment it is often likely to be as effective for some conditions... Additionally, there are testimonies online of people who used erythromycin for strep with no initial benefit then after a few rounds saw benefit. I definitely understand your concern though.
What I beleive is that if your strep is gone in your repeat testing and some of your symptoms are still present then maybe these remaining symptoms may be due to something else. Unless you have a reason to suspect that strep is still lingering and there is some evidence for it, you should consider looking for another cause.

I think that a lot of symptoms are probably caused directly by the bacteria toxins and also the immune response and antibodies produced. So once the bacteria are gone then symptoms should fade. Some evidence shows that for example in pandas patients using antibiotics and ivig to remove antibodies causes rapid reversal in ocd symptoms. Also for interest without ivig, but only with antibiotics apparently it takes a few months for the ocd symptoms to disappear, which probably is the time it takes for the antibodies to die off rather than the bacteria which probably dies much earlier on. So maybe this may also be an answer for you Elph. Maybe you should just make sure to keep the strep levels low now that you have treated it and maybe the autoimmune symptoms will take a little time to fade.
Just a thought
This is where i am stuck Derek, i still have a sore throat, eyes, nose and prostate, mouth ulcers and burning red blotchy skin on my face .... my lymph nodes are swollen ... My immune system can't beat it .... still too big a fight and there is still risk of transfer into my gut again .....
