Abstract

Methicillin-resistant Staphylococcus aureus (MRSA) has emerged as an important pathogen in community-acquired and nosocomial infections. The unique bactericidal action of mupirocin makes it one of the few antibiotics still effective against MRSA. The purpose of this study was to investigate the mupirocin resistance in MRSA strains isolated from wound infections of in- and out-patients of two distinct hospitals located in Ankara and Istanbul. A total of 143 MRSA strains were included in the study. Mupirocin resistance was investigated by Kirby-Bauer disk diffusion method and theresults were confirmed by determination of the MIC values by E-test strips. Among 143 MRSA isolates, mupirocin resistance was detected by none of the methods, and overall mupirocin sensitivity was detected as 100 percent. The majority of mupirocin resistant MRSA is isolated from wound infections. The aetiology mostly depends on the increased topical use of the agent. The method used in the detection of mupirocin resistance and interpretation of the results are important parameters in the determination of mupirocin resistance in MRSA strains. Since there was no resistant strain among 143 clinical isolates obtained from two different hospitals, it was concluded that, mupirocin resistance is not an important problem in these regions currently, and mupirocin may be safely used in treating wound infections.

Özet

Metisiline dirençli Staphylococcus aureus (MRSA) izolatları, hem toplumdan kazanılan hem de nozokomiyal enfeksiyonlarda önemli bir etken olarak karşımıza çıkmaktadır. Mupirosin, MRSA izolatlarına halen etkili bir kaç antibiyotikten birisidir. Bu çalışmanın amacı, Ankara ve İstanbul'daki iki farklı hastanede yatarak ve ayaktan takip edilen hastalardaki yaralardan izole edilen MRSA suşlarında mupirosin direncinin saptanmasıdır. Çalışmada, toplam 143 MRSA izolatında, Kirby-Bauer disk difüzyon yöntemi ile mupirosin direnci araştırılmış ve sonuçlar E-test yöntemi ile MİK saptanarak doğrulanmıştır. Hem disk difüzyon hem de E-test yöntemi ile mupirosin direnci gösterilememiş ve toplam 143 MRSA izolatının mupirosine duyarlılığı %100 olarak saptanmıştır. Mupirosine dirençli MRSA izolatları sıklıkla yara kültürlerinden izole edilmektedir. Bu dirençten, büyük oranda topikal mupirosin kullanımı sorumlu tutulmaktadır. MRSA'larda mupirosin direncinin saptanmasında, seçilecek laboratuvar yöntemi ve sonuçların yorumlanması önemli parametreler olarak dikkat çekmektedir. Çalışmamızda iki farklı hastaneden izole edilen 143 MRSA izolatında mupirosin direncinin saptanmamış olması, bu bölgelerimiz açısından en azından şimdilik bir direnç problemi olmadığını göstermektedir. Dolayısıyla mupirosin, özellikle yara enfeksiyonlarının topikal tedavisinde güvenle kullanılabilecek bir antibiyotiktir.
