A 29-year-old female asked:
How would you treat a bladder infection from group b strep (tested, high number of colonies) that doesn't respond to ampicillin/penicillin?

Very unusual: This is almost impossible: GBS is uniformly susceptible to ampicillin and related penicillins. You may need testing to confirm if you are now infected with a different bacteria; and whether you still have a urinary tract infection or some other explanation for your symptoms (e.g., STDs like chlamydia or gonorrhea). Discuss with your doctor. Good luck!
