instruction: hi doctor I am a 49 year old woman and last month I was hospitalized with a necrotizing soft tissue infection on my thigh I had two debridement surgeries and was discharged after days I was treated with about iv antibiotics I do not remember them all I recall seeing vancomycin and penicillin I was told that the infection was not mesa but a slower moving bacteria they did not tell me what it was I was swabbed for mesa in my nose and butt before both surgeries and was told I did not have it for the last day of my stay I had a roommate who had a bad mesa infection on her butt and sometimes had diarrhea incontinence during dressing changes I had no physical contact with her but we had the same nurse I was discharged with a five day course of augmenting the wound has been healing very well and has not gotten infected but three weeks after discharge I got an abscess under my arm I went to an urgent care and was prescribed clindamycin and told to return in three days for drainage the abscess did not improve or get worse over the three days I got it drained and was prescribed augmenting and told to also continue the clindamycin that was a week ago and the wound is healing well they called today and said cultures show it was mesa and they prescribed bactrim and told me to stop the other antibiotics I am feeling devastated by this and wanting to understand why it happened could I have gotten it in the hospital I am concerned that it will not go away are those swabs at the hospital conclusive and mean for sure I did not have mesa a month ago I have never had any medical problems before and these experiences have been very frightening is there anything else I can do to prevent recurrence I have read about everything from bleach baths and hibiclens to antibiotics in the nose
output: hi I am sorry for what you have had to go through as you previously did not have mesa strains it is possible that now you have hospital acquired strains in your blood it is a superbug and superdifficult to treat as it is resistant to drugs of choice so you have get culture and sensitivity test to find out which one is it sensitive to as you were told to stop other antibiotics and start bactrim this means the strain you have got is sensitive to bactrim if there is anything else you want to ask please feel free to contact me
