Study on the prevalence of enterobacteriacae in hospital acquired and community acquired infections

ABSTRACT

A study was conducted during the period September 1999 to August 2000 at Clinical Microbiology Laboratory, Public Health Division, National Institute of Health; Islamabad, Pakistan, to find out the incidence of Eriterobacteriaceae in nosocomial and community acquired infections. Two hundred OPD [out patient department] isolates and two hundred nosocomial isolates from different wards [Oncology, Post-operative surgical, Kidney transplant center / Urology wards and Intensive care unit] of Pakistan Institute of Medical Sciences [PIMS] Islamabad, Pakistan, were collected for the study. The bacterial strains were isolated from pus, sputum, blood, urine, pleural fluid, peritoneal fluid and cerebro- spinal fluid [CSF]. The isolates were identified on the basis of standard microbiological and biochemical techniques. The incidence of Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Proteus vulgaris Enterobacter cloacae and Citrobacter freundii was studied according to their distribution among different wards /nosocomial patients, specimens and age groups of patients
