Özet

Kocaeli University Medical School was established in 1995. The first methicillin resistant Staphylococcus aureus isolate was detected two years later in a patient transferred from a different city. Six months after this, we detected a small MRSA outbreak in the intensive care unit involving four patients, two of whom had bacteremia, and a staff nasal carrier. All isolates, including the first, appeared to be a single outbreak strain, demonstrated by pulsed field gel electrophoresis profiles which different by at most two bands, identical randomly amplified polymorphic DNA profiles, and identical coagulase gene types by PCR. Antibiogram were identical except that one isolate was additionally resistant to cotrimoxazole. These results show that MRSA isolates can spread between hospitals with infected or colonized patients and can apparently persist in the hospital for six months without causing infection. Screening of asymptomatic patients on wards affected by MRSA or transferred from other hospitals may be helpful in controlling these infections.
