El kurutma makinelerden üflenen havanın mikrobiyolojik özellikleri

Araştırmanın amacı sıcak hava üfleyerek çalışan el kurutma makinelerinden üflenen havanın mikrobiyolojik özelliklerini belirlemek ve bu makinelerin yerleştirildikleri yerlerdeki kapalı ortam havasını karşılaştırmaktır. Hava örnekleri toplum tarafından ortak olarak kullanılan çeşitli yerlerden (alışveriş merkezleri, restoranlar ve hastaneler) alınmış ve toplam canlı sayısı, koagülaz negatif Stafilokoklar, E. coli, Staphylococcus aureus ve enterik patojenler açısından incelenmiştir. Bazı mikroorganizmalar için örnekleme yapılan kapalı ortamlara göre değişiklikler bulunmakla birlikte, el kurutma makinelerinden alınan hava örneklerinin hepsinde, enterik patojenler dışındaki tüm mikroorganizmaların, aynı ortam havasından daha fazla mikroorganizma içerdiği görülmüş ve kapalı ortamla aralarında istatistiksel olarak anlamlı farklılık saptanmıştır (p

Microbiological characteristics of the air blown by warm air hand dryers

The aim of the study was to determine the microbiological characteristics of air blown from warm air hand dryers, and to compare findings with the microbiological characteristics of indoor air in which the dryer settled. Air samples was taken from different public places (shopping centers, restaurants and hospitals) and investigated for total viable counts, coagulase negative Staphylococcus, E. Coli, Staphylococcus aureus and enteric pathogens. There were differences between sampling indoor places for some of the microorganisms, but all of the air samples taken from dryers contained more microorganisms than indoor air, and the differences between hand dryers and indoor air were statistically significant (p<0.05) except for enteric pathogens. As a result it could be said that warm air hand dryers could be microbiological contamination sources in restrooms or the other places that they are used.
