Abstract

Aim: The aim of this study was to determine the incidence of macrolide-lincosamide-streptogramin B (MLSB) resistance in staphylococcal isolates from various clinical samples. Methods: In this study, we included a total of 100 staphylococcal isolates, 35 Staphylococcus aureus and 65 coagulase-negative staphylococci (CNS), from specimens obtained from patients followed up in our hospital between 2009 and 2010. Methicillin resistance of these isolates was determined using cefoxitin disc diffusion method. MLSB resistance was investigated by D-test method using erythromycin and clindamycin disks. Results: Of 35 S. aureus isolates, 14 were methicillin-resistant (MRSA) and 21 were methicillin-sensitive (MSSA). Of 65 CNS isolates, 41 were methicillin-resistant (MRCNS) and 24 were methicillin-sensitive (MSCNS). In 79 strains, there was at least one MLSB resistance phenotype. The most frequent resistance phenotypes were inducible (35%) and constitutive (30%) among all isolates, while the constitutive one was more common in S. aureus strains (62%). Conclusion: Since the resistant community- and hospital-acquired staphylococcal infections have become a therapeutic problem, it is very important to detect MLSB resistance routinely in microbiology laboratories. D-test is a cheap and reliable diagnostic method which can be performed in every laboratory. In order to prevent treatment failure, D-test should be routinely used and the results should be reported to the clinician before starting a therapy with MLSB group of antibiotics.

Özet

Amaç: Bu çalışmada, çeşitli klinik örneklerden izole edilen stafilokok suşlarında makrolid-linkozamid-streptogramin B (MLSB) direnci ve fenotiplerinin belirlenmesi amaçlanmıştır. Yöntemler: Hastanemizde 2009-2010 yılları arasında takip edilen hastalara ait klinik örneklerden izole edilen 35'i Staphylococcus aureus ve 65'i koagülaz negatif stafilokok (KNS) olmak üzere, toplam 100 stafilok suşu çalışmaya dahil edildi. Metisilin direnci disk difüzyon yöntemiyle sefoksitin diski kullanılarak, MLSB direnci ise eritromisin ve klindamisin diskleri kullanılarak uygulanan D test yöntemiyle araştırıldı. Bulgular: İzole edilen 35 S. aureus suşunun 14'ü metisiline dirençli (MRSA), 21'i metisiline duyarlı (MSSA); 65 KNS'nin 41'i metisiline dirençli (MRKNS), 24'ü metisiline duyarlı (MSKNS) idi. İzole edilen 100 suştan 79'unda MLSB direnç fenotiplerinden biri tespit edildi. Tüm suşlar arasında en sık saptanan direnç fenotipi indüklenebilir (%35) ve yapısal (%30), S. aureus suşlarında ise yapısal dirençtir (%62). Sonuç: Tedavide sorun oluşturan toplum ve hastane kaynaklı dirençli stafilokok infeksiyonlarında, MLSB direncinin mikrobiyoloji laboratuvarlarında rutin olarak ortaya konması önemlidir. D-test yöntemi, her laboratuvarda uygulanabilecek, ucuz ve güvenilir bir yöntemdir. Tedavi başarısızlığının önlenmesi için; MLSB grubu antibiyotik tedavisinden önce, bu test uygulanmalı ve kli-nisyene bildirilmelidir.
