My husband contracted ecoli in a nursing home, but the health dept says the facility told them he may have had it before he got there and it just grew to detectable amounts. He had been there for 6 months and had cultures before and it was never present. The infection was at his tracheostomy site and he is bedridden doesn t move doesn t care for himself and he is changed by aides who I ve seen wipe his bowel movements and put on cream and clothes without changing their gloves.My husbands physician told me that ecoli should not be present at a tracheostomy site and that it was more than likely due to unsanitary practices . Who is correct?
