Hi Doctor, A sputum test results were showing that I got an unusual bacteria called citrobacter koseri. I was given antibiotic Cipro for 7 days to cure it. After that, I had to do a sputum test again to see if it is gone, but it is still there. I was given another antibiotic called Apo-Sulfatrim DS 800/160mg for 10 days now by my doctor and I am on it. I wonder if this medicine will actually kill this bacteria forever or not. I am also a carrier of TB. Do you think that me being a carrier, I am more prone to that bacteria? I have 5 more days to finish my medication and hope that is going to be cured forever. Please let me know if maybe I should go to the hospital and have an IV treatment for it, or this medication will help me to get rid of it.
