Antimicrobials Sensitivity of Gram- Positive and Gram- Negative Bacteria Isolated from Urinary Tract Infections in Mosul City

Abstract

250 samples of urine, 191 female and 59 male with different age (3 month to 80 years) in the period from September 2012 till January 2013, were collected from patients suspected to be infected with UTI from Al- Zahrawi and Ibn- Sinna hospital in Mosul city. Samples were cultured on selective media, the isolates were diagnosed according to the cultural & morphological characteristics, biochemical tests and API 20E. 127 isolates obtained (51%) belonged to Gram positive and Gram negative bacteria and yeasts. Staphylococcus aureus was the most isolated bacteria with (42.5%) followed by Escherichia coli with ( 21.3%), while other species were different in isolation rates. The activity of antimicrobials showed absolute sensitivity to (IMP) Imipenem against Gram negative bacteria while these isolates were more resistant to (IMC) Amoxicillin-Clavulinic acid, (RA) Rifampin, (AM) Ampicillin, while the Gram positive bacteria were sensitive to (VA) Vancomycin (100%) and highly resistant to (DA) Clindamycin, (E) Erythromycin and (ME) Methicillin.
