Abstract

Aim This study aims at investigating and testing the tentative antimicrobial efficacy; in vitro and in- hospital applications of apatite coated ferrum titanate which is one of the new generation photocatalysts. Material and Methods 30 sterile petri dishes were kept under florescent light for 4 days following the application of 20 ppm apatite coated ferrum titanate aerosol. 0.5 McFarland (1.5X108 CFU/mL -CFU=colony forming unit) Pseudomonas aeruginosa and 0.5 McFarland Acinetobacter baumannii were cultured on 10 separate dishes. 10 unprocessed dishes were used as controls. Samples were evaluated for bacterial survival rate (CFUX100/CFU) after application. In the second step, same photocatalyst aerosol was applied as 0.012 L/m2 with the specific kit on the surfaces of different units within the hospital. Particle count was measured and compared before and one-month after the photocatalyst application by lumimeter. Results Bacterial survival rate was significantly lower on photocatalyst applied surfaces versus control for Pseudomonas aeruginosa after second day of application (p

Özet

Amaç Çalışmamız yeni kuşak fotokatalizörlerden olan apatit kaplı demir titanat uygulamasının, olası anti-mikrobiyal etkinliğinin araştırılmasını; in vitro ve hastane içi uygulamalarda test edilmesini amaçlamaktadır. Gereç ve Yöntemler 30 adet standart steril petri kutusu buhar fazında 20 ppm apatit kaplı demir titanat uygulamasına tabi tutulduktan sonra floresan ışık altında 4 gün tutuldu. 10 kutuya 0,5 McFarland (1.5X108 CFU/mL -CFU=koloni oluşturucu birim) Pseudomonas aeruginosa, 10 kutuya 0,5 McFarland Acinetobacter baumannii ekimi yapıldı. 10 kutu ise kontrol olarak saklandı. Örnekler uygulama sonrası bakteriyel sağkalım oranı (CFUX100/CFU) yönünden değerlendirildi. İkinci aşamada hastanede belli mekânlarda yüzeylere özel uygulama kitiyle buhar fazında 0.012 L/m2 uygulama yapıldı. Fotokatalizör uygulamasından hemen önce ve 1 ay sonra havadaki parçacık miktarı lumimetre ile ölçülerek karşılaştırıldı. Bulgular Bakteriyel sağkalım oranları Pseudomonas aeruginosa için fotokatalizör kaplı yüzeylerde kontrol grubuna oranla 2. günden sonra anlamlı olarak azalmış bulundu (p
