Ph, I don't doubt the problems with the right drug. My test culture was done in hospital in Oct/Nov and with the CDC's overview, that was when I went on IV enterpenem for 10 days. Checked clear and almost immediately got an infection. I am suspecting this originates in my kidneys so left a sample just now at UTI specialist I started with two weeks ago. If all this doesn't work soon, I will try to get into Mayo's. I am too old to be messing around, at 78 yrs. Thanks.
