Abstract

Objective: The aim of this study is evaluation of StaResMet®(AYCMED Medikal ve Tıbbi Cihazlar San. ve Tic. A.Ş., Samsun, Turkey) as a new colorimetric test kit for rapid detection of the methicillin resistance in Staphylococcus aureus isolates.Methods: Methicillin resistance was determined by the microdilution method according to Clinical & Laboratory Standards Institute (CLSI) recommendations. The StaResMet® kit and VITEK® 2 Compact (bioMérieux, Marcy l'Etoile, France) automated system were used according to the recommendations of the manufacturers. The broth microdilution test was considered as reference method for the comparison of the tests. S. aureus ATCC 29213 (methicillin-susceptible) and ATCC 43300 (methicillin-resistant) were used as quality control strains. Isolates were accepted as resistant to methicillin if they had a cefoxitin minimum inhibitory concentration of ≥8 µg/ml according to the CLSI criteria.Results: It was found that out of 277 isolates, 118 S. aureus isolates were methicillin-resistant and 159 were susceptible to methicillin. It was determined that 118 S. aureus isolates were resistant to methicillin by the broth microdilution method, VITEK® 2 Compact and StasResMet® kits. 159 isolates were susceptible to methicillin by three methods. According to these results, specificity, sensitivity, positive and negative predictive values of StaResMet® kit were 100%.Conclusions: StaResMet® kit has a potential use for rapid detection of methicillin-resistant S. aureus (MRSA).Klimik Dergisi 2017; 30(2): 64-7

Özet

Amaç: Çalışmada, Staphylococcus aureus izolatlarında metisilin direncinin hızlı tespitinde yeni bir kolorimetrik test kiti olan StaResMet® (AYCMED Medikal ve Tıbbi Cihazlar San. ve Tic. A.Ş., Samsun, Türkiye)'in değerlendirilmesi amaçlanmıştır. Yöntemler: Metisilin direncini belirlemede Clinical & Laboratory Standards Institute (CLSI) önerileri doğrultusunda mikrodilüsyon yöntemi uygulandı. StaResMet® kitinin ve VITEK®2 Compact (bioMérieux, Marcy l'Etoile, Fransa) otomatize sisteminin çalışması üretici firma önerileri doğrultusunda yapıldı. Testlerin karşılaştırılmaları için mikrodilüsyon testi referans olarak kabul edildi. Kalite kontrol suşları olarak S. aureus ATCC 29213 (metisiline duyarlı) ve ATCC 43300 (metisiline dirençli) kullanıldı. CLSI kriterlerine göre sefoksitinin minimum inhibitör konsantrasyonu >=8 µg/ml olan suşlar metisiline dirençli olarak kabul edildi.Bulgular: 277 izolattan 118 S. aureus izolatı metisiline dirençli, 159 izolat metisiline duyarlı bulunmuştur. 118 S. aureus izolatı VITEK® 2 Compact otomatize sistemi, sıvı mikrodilüsyon yöntemi ve StaResMet® kitiyle yapılan duyarlılık testleriyle metisiline dirençli olarak saptanmıştır. 159 izolat ise her üç yöntemle de metisiline duyarlı bulunmuştur. Buna göre StaResMet® testinin özgüllük, duyarlılık, pozitif ve negatif prediktif değerleri %100 olarak belirlenmiştir.Sonuçlar: StaResMet® kiti metisiline dirençli S. aureus (MRSA)'nın hızlı tespiti için bir kullanım potansiyeline sahiptir.Klimik Dergisi 2017; 30(2): 64-7
