The Survey of Microbial Contamination of Used Liquid Soaps in the Hospitala of Ilam City in 2010

Washing hand hygienically before having contact with patient is one of necessities for controlling of nosocomial infections because hands are main way for transferring of microorganism in hospital environments. In such a circumstance، if the protective agent contains pathogens، it can lead to nosocomial infections growth. In the study we dealt with microbial pollution of used liquid soaps in five hospitals of Ilam city in 2010. The samples were taken by sterile tubes containing physiology serum، after this they were cultivated on Differential and base the cultures. After 18-24 hours، the initials cultures were studied for the prtent of bacteria. In order to differential separation we used usual microbiology methods. In the study in respect of microbial pollution nearly 95% of samples were positive and 38. 1% negative and 2. 4% unknown. The most microbial pollution in all samples was for Pseud-omonas (22. 6%) and the least was Klebsi-ella (8. 3%). In different units of hospitals، there was a significant difference among the units (P=0. 002)، and also there was a significant among different hospitals and types of microbes (P=0. 002). Discussion & It seems that the application of guidelines for how to use soaps and the conditions of hand washing has an important role in reduction of contamination، and with attention to the contamination of main reservoir، it is essential that contamination discussion of provided soaps in factory to be addressed certainly and in the case of having quality control problem، we do more attention on production lines.
