Résumé
Nosocomial infections in general were studied on patients bedded in three hospitals in Erbil during June-September/1992. Escherichia Coli, Klebsiella, Pseudomonas, Staphylococcus aureas and Streptococcus were the pathogenic microorganisms isolated in 80 swab samples from different specimens at Saddam hospital, Erbil teaching hospital and Casualty and Orthopedic hospital. The same pathogenic microorganisms were detected in 120 patients studied; 33-50% and 30% of the admitted patients were infected after their admission to surgical and medical wards, respectively. Each hospital has its predominant microorganisms; 66% of them were pseudomonas in Casualty and Orthopedic hospital. While 70% of them were Klebsiella in Saddam hospital and 68% of them were Escherichia Coli in Erbil teaching hospital. All the pathogenic microorganisms were resistant to Ampicillin which was prescribed for most of the patients in this study and sensitive to Gentamicin, Cephalexin and Tetracycline
