Abstract

In this study, the efficacy of two recently marketed multipurpose contact lens disinfecting solutions against Staphylococcus aureus Rosenbach and Pseudomonas aeruginosa Gessard bacteria isolated from clinical specimens were investigated. The antibacterial activities of multipurpose contact lens disinfecting solutions were determined by microbiological culture method described in ISO 14729 guidelines. Bacterial counts were obtained for sampling intervals determined in addition to the manufacturer’s minimum recommended disinfection time and mean log reductions were calculated for each interval. Three different lots of each contact lens disinfecting solutions were used. The results showed that both contact lens disinfecting solutions provided at least 3 log reductions for all bacteria tested at the end of the manufacturer’s minimum recommended disinfection time. New formulations are being developed in contact lens disinfecting solution industry by new technologies and scientific researches. Further studies on strains isolated from different sources are needed in order to a complete understanding of these newly marketed contact lens solutions.

Özet

Bu çalışmada, son yıllarda piyasada satışa sunulan iki adet çok amaçlı kontakt lens dezenfektan solüsyonunun klinik örneklerden izole edilen Staphylococcus aureus Rosenbach ve Pseudomonas aeruginosa Gessard bakterilerine karşı etkinliği araştırılmıştır. Çok amaçlı kontakt lens dezenfektan solüsyonlarının antibakteriyal etkinlikleri ISO 14729’da belirtilen kültüre dayalı mikrobiyolojik yöntem kullanılarak belirlenmiştir. Üretici tarafından önerilen minimum dezenfeksiyon sürelerine ek olarak belirlenen örnekleme saatlerindeki bakteri sayıları tespit edilmiş ve ortalama log düşüşleri hesaplanmıştır. Çalışmada antibakteriyal etkinlikleri test edilen bu kontakt lens dezenfektan solüsyonlarının 3 farklı lotu kullanılmıştır. Elde edilen sonuçlar, her iki kontakt lens dezenfektan solüsyonunun üretici tarafından önerilen minimum dezenfeksiyon süresi sonunda denenen bakterilerin sayılarında en az 3 log düşüş sağladığını göstermiştir. Kontakt lens solüsyon endüstrisinde gelişen teknolojiler ve yapılan bilimsel çalışmalar ile yeni formülasyonlar geliştirilmektedir. Piyasada satışa sunulan bu yeni ürünlerin antibakteriyal aktivitelerinin tam olarak anlaşılabilmesi için farklı kaynaklardan izole edilen suşların kullanılacağı ileriki çalışmalara ihtiyaç duyulmaktadır
