Effect of Halamide (0.5%) on Microorganisms Isolated from Tabriz University Girlsʹ Accommodation

Background and Objectives: Presence of microorganisms in places with crowded population, is associated with potential risk of infection transmission. This study was carried out in girlsʹ accommodation (Fajr 2) in Tabriz University of Medical Sciences. Disinfectant halamide (51.5%) was used to eliminate microorganisms when the building was changed to university accommodation. The aim of this study, was to evaluate the efficacy of halamide in different areas of this accommodation and to compare microorganisms with those isolated from another accommodation, Fajr 1. Materials and Methods: Samples were collected using sterile swabs impregnated with salin, and were immediately placed into trypticase soy broth. After incubation for 24h at 37 C, blood agar and EMB plates were inoculated. For detection of fungi, Sahourads dextrose agar with and without chloramphenicoi and cyclohexamide were inoculated, and incubated at 25 C. Results: Our results indicated the presence of potential pathogenic organisms such as: I) P. aerouginosa; 2) bacteria often isolated from nosocomial infections such as E.coli, klebsiella spp., and proteus spp; and 3) opportunistic bacteria such as staphylococcus epidcrmidis and bacillus subtilis. Fugi isolated in this study, included candida and saprophytic mycelia) fungi. Comparison of isolated microorganisms revealed greater prevalence and diversity of gram-negative bacteria and fungi in the university accommodation Fajr 2, campared with Fajr f accommodation. Conclusion: Results obtained in this study, showe inefficacy of halamide (0.5%) in eliminating gram-negative bacteria and spores of saprophytic fungi and indicate the need for more effective disinfectants.
