HASTANE KÖKENLİ KLİNİK OLMAYAN Staphylococcus aureus SUŞLARININ ANTİMİKROBİYAL DUYARLILIKLARININ ARAŞTIRILMASI

Abstract

Methicillin resistant Staphylococcus aureus (MRSA) is one of the most important factors in hospital acquired infections. This study aims at revealing the antimicrobial sensitivity of nonclinical S. aureus isolates with potential significance with respect to hospital acquired infections. To this end, mannitol salt agar was cultured from swab samples obtained from the personnel, patients, patient accompanists in the state hospital of our city and the hospital environment and identification of suspicious isolates that reproduce was carried out through classical methods. Manifestation of the antimicrobial sensitivity thereof, on the other hand, was carried out through the disc diffusion method. In the study, 22 (28,21%) S. aureus were isolated from a total of 78 samples. While oxacillin resistance was detected in six (27.27%) of the strains, inducible clindamycin resistance was found out again in 2 (9.1%; one of the strains is MRSA, the other is MSSA) of the strains. In conclusion, detection of MRSA in the samples studied and, also, of inducible resistance to clindamycin which is one of the treatment alternatives, reveals the necessity to take the required precautions with respect to the prevention of possible infections resulting from these strains
