Methods: The study included 81 Serratia marcescens strains isolated from 61 patients hospitalized in the in the different hospital wards of Al-Noor Specialist Hospital within the period from 1/11/2012 to 1/11/2013. The strains were isolated from wound swabs, blood cultures, sputum, urine culture, fluid, catheter and throat swab, wound swabs, blood cultures and cerebrospinal fluid. Results: The isolates were identified by conventional method and the results and susceptibility testing were confirmed by VITEC-2 Compact. Most frequently Serratia marcescens has been implicated in ICU [21%] followed by male medical [18.5%] and emergency department [12.3%]. The resistance of Serratia strains was high, excepting imipenem (15%), Meropenem (27) and the resistance was higher with ampicillin (97.5%), Cefoxitin (90%) and Tetracycline (86%). Conclusion: Continuous monitoring of nosocomial infections is indispensable. Phenotypic characterization of the isolates is useful for studying the relationship of microbial pathogens. %K < %K i> %K Serratia marcescens< %K /i> %K Antimicrobial Resistance %K Nosocomial ?nfection %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=58781
