Hi Kathi- Yes i have cultured cerratia in the past. I havent seen it for a long time now, so i guess i got rid of it. I am on oral antibiotics all the time and iv's maybe two times a year . I am sure one of those took care of it. I never even knew i had it, but saw it on the result sheet and thought they spelled cepacia wrong. Thats when my doctor correctedme and said there is something called cerratia. I have not seen it on my results sheet in a while now though. The less on that sheet, the better! Good luck! ~ Diane
