STAPHYLOCOCCUS EPIDERMIDIS VE ESCHERICHIA COLI ’NİN ÇEŞİTLİ CERRAHİ İPLİKLERE YAPIŞMA DAVRANIŞLARI

Cerrahi iplikler, ameliyat tipine, yerine ve derecesine bağlı olarak farklı özellik taşıyan biyomalzemelerdir. Çalışmamızda kollojen Kromo katgüt® , poliglikolat Dexon® , poliglikolat’laktat Vicryl® , polidioksanon PDS® ve poliprofilen Prolen® bazlı beş farklı cerrahi ipliğe Escherichia coli ve Stopylococcus epidermidis’in dinamik şartlarda yapışma davranışları araştırılmış, çalkalama sıvılarındaki bakteri sayısı ‘‘Plak Sayım Yöntemi’’ ile saptanmıştır. Her iki suş beş farklı cerrahi ipliğe farklı zamanlarda farklı adsorbsiyon ve desorbsiyon göstermişlerdir. S. epidermidis suşu en fazla Vicryl®’e yapışırken, diğer iplikler Dekson, K.Katgüt, Prolen, PDS şeklinde sıralanmıştır. E.coli suşu en çok Dekson’a yapışırken diğer iplikler sırasıyla; Vicryl®; K.Katgüt®, Prolen®, PDS® ş e k l i n d e belirlenmiştir. Her iki suşun beş cerrahi ipliğe olan yapışma davranışları karşılaştırıldığında, S . e p i d e r m i d i s’ i n , Vicryl® hariç diğer ipliklere E.coli ’den daha az yapışma gösterdiği belirlenmiştir.

Adhesion Behaviours Of Staphylococcus Epidermidis And Escherıchia Coli On Different Surgery Sutures

Surgical sutures are biodevices that vary especially according to type, location, and level of operation. In our study, cromic catgut, polyglycolate Dexon® , polyglycolate/lactate Vicryl® , polydioxanone PDS® ve polypropylene Prolen® were investigated according to adhesive behavior of E.coli and S.epidermidis under dynamic conditions. Number of bacteria in washing solution was determined by plate count method. Both strains, showed different absorption and desorption to five different surgical catguts in different times. While S.epidermidis strain behaved as the most adhesive to Vicryl®, the others were Dexon®, cromic catgut® , Prolen®, and PDS respectively. While E.coli strain behaved as the most adhesive to Dexon®, the others were Vicryl®, Cromic catgut®, Prolen®, PDS® respectively. When both strains were compared with each other in terms of their total adhesion to five surgical catguts, S.epidermidis adhered less to the other catguts, except Vicryl® than E.coli.
