Incidence and Isolation of Bacteria Associated With Nosocomial Urinary Tract Infection (UTI) in Sudanese Women

Suzan A. Shareef and Sanaa O. Yagoub    

Abstract: One hunderd and sixty three 14-82 year old women hospitalized at the Departments of Surgery and Medicine, Khartoum Teaching Hospital and co-patients women, nurses and workers were investigated for urinary tract infection. The number of women who had significant bacteriuria (105) was 94; 53 of them were symptomatic while 41 were asymptomatic. From the total of 100 bacterial strains that were isolated from the urine samples, (85%) of them were Gram-negative rods and (15%) were Gram-positive cocci. The Gram-negative bacilli were identified as Escherichia coli (49.4%), Proteus mirabilis (14.1%), Pseudomonas aeruginosa (10.6%), Klebsiella pneumoniae (5.9%), Citrobacter freundii (5.9%) and the rest belonged to the family Enterobacteriaceae. The Gram positive cocci were Staphylococcus spp. and 6 of them were coagulase- positive. The factors that affected the incidence of bacteriuria were age, duration of hospitalization and catheterization. Poor hygiene affected the incidence of the bacteriuria and was frequently observed among workers than nurses.
