And strep can be a little resistant.
Augmentin does usually knock it out though. I took antibiotics
for a full month around the clock
for a tooth issue (yes, 4 times a day and got up at night or it). I was fine during. About two weeks after stopping, all heck broke loose in my GI track. I did get a yeast infection and treated that. BUT, I had a day in which I was horribly ill. I had stomach cramping, nausea and diarrhea. It was brutal.
