current spectrum of bacterial infections in patients with nosocomial fever and neutropenia

background: neutropenic patients are vulnerable to a wide spectrum of infectious agents. the aim of this study was to determine the current frequency of bacterial infections in patients with nosocomial fever and neutropenia. methods: in a retrospective study, the neutropenic patients’ specimens with nosocomial fever were cultured on blood and macconkey agar plates and evaluated at microbiology laboratory. ninety-five significant isolates as species level were recognized by bacteriological techniques.results: the most observed microorganism was escherichia coli, followed by pseudomonas aeruginosa, acinetobacter baumanii, klebsiella pneumoniae, coagulase positive staphylococci and coagulase negative staphylococci. one fungal infection was also observed. overall, 67% of the organisms were gram negative, 29.8% gram positive, and 3.2% polymicrobial. conclusion: the changing pattern of infectious agents in neutropenic patients overtime postulates the necessity of other studies to give the most up-to-date insight of the organisms to physicians.
