Abstract
Objective: The aim of this study is to determine the species distribution, slime activity, and methicillin resistance of coagulase-negativestaphylococci (CoNS) isolated from blood cultures as either contaminants or true bacteremia agents.Materials and Methods: In this study, 13.268 blood culture samplessent to our laboratory from various clinics during a two-year periodwere examined in terms of the presence of CoNS to clarify whetherthe isolates are true bacteremia agents, as defined by Centers for Disease Control and Prevention (CDC) criteria. The slime activities of truebacteremia agents (58 CoNS strains) and contaminants (50 randomlyselected CoNS strains) were investigated by the Christensen method.The methicillin susceptibilities of the strains were determined by thedisk diffusion method.Results: Although the frequency of slime production was 39.7% among the true bacteremia CoNS agents, it was 18% in CoNS that were judged to be contaminants (p
Özet
Amaç: Bu çalışmada kontaminant ve gerçek bakteremi etkeni olarak soyutlanan koagülaz negatif stafilokokların (KNS), tür düzeyinde tanımlanması, slime aktiviteleri, metisiline direnç oranlarının saptanması amaçlanmıştır. Gereç ve Yöntem: Çalışmada iki yıllık süreçte çeşitli kliniklerindengönderilen 13,268 kan kültürü örneği KNS üremesi yönünden değerlendirildi. Kan kültürlerindeki üremenin gerçek bakteremi etkeni KNSolup olmadığı, Centers for Disease Control and Prevention (CDC) kriterleri kullanılarak belirlendi. Gerçek bakteremi etkeni 58 KNS ve randomize seçilen 50 kontaminant KNS suşuna ait slime aktivitesi Christensen yöntemi ile araştırıldı. Bu KNS’lere ait metisilin duyarlılıkları disk difüzyon methodu uygulanarak belirlendi. Bulgular: Slime üretme oranı gerçek bakteremi etkeni olarak saptanan KNS’lerde %39,7 iken kontaminant KNS’lerde ise bu oran %18 olarak saptanmıştır (p
