Pattern of Nosocomial Urinary Tract Infections among Sudanese Patients

Abstract

Background: High incidence of nosocomial infections has led to prolonged hospitalization, leading to high morbidity and mortality. Our research was aimed at determining the prevalence as well as identification and isolation of aerobic bacteria responsible for nosocomial urinary tract infection. Methods: Study was conducted at Gadarif Teaching Hospital, Gadarif State, Eastern Sudan, from April 2004 to March 2005. The study was designed to isolate aerobic bacteria causing urinary tract infections, and to determine the antibiograms of the isolated bacteria to commonly used antibiotics. Results: Out of 783 specimens collected during the study, 611 (79.03%) midstream urine specimens were collected from patients after urinary catheterization. 100 (12.77%) aerobic bacterial species were isolated from these specimens, they were P. aeruginosa (37%), K. pneumoniae (23%), P. mirabilis (22%), P. vulgaris (12%) and E. coli (6%); The antibiograms of the isolates (n=263) shows sensitivity and resistant to S. aureus (n=103), P. mirabilis (n=63), P. aeruginosa (n=49), K. pneumoniae (n=23), P. vulgaris (n=14) and E. coli (n=11) bacteria to various antibiotics including Vancomycin,
