300 samples (Environmental swabs) were collected from different sites of the restroom (the ladies) in the dormitory with AL-Qadisiya university for period: September (2007) –september (2008).
In this study we got 560 isolates of various aerobic microorganisms, tot al bacterial isolates were (459), (%82) while total Molds and Yeasts isolates were (150) , (%33).
The bacterial isolates included: 309 isolates (%67) were gram negative bacteria while 150 isolates (%33) were gram positive bacteria. Enterobacteriaceae was the most common gram negative bacteria (%79) and the Enterococci was the most common gram positive bacteria (%67). We have a clear difference in the percentage of microbial contamination among the sites. The floor and air samples showed the highest growth percentage (%100) with highest count of isolates (162) and (129), while the kitchen sink samples have the lowest growth percentage (%82) with lowest count of isolates (75).
On the other hand, certain tests were performed on Dettol and Sodium hypochlorites solutions with concentrations (10 , 25 , 50) mg/m. Sodium hypochlorites had the highest proinhibition effect on all the microorganisms, Pseudomonas aeruginosa was the most sensitivity to it while Staphylococcus aureus was the least sensitivity.
