A collective of 1178 different isolates were collected and identified from clinical specimens of human patients and these sources include urine (n=641), swab (n=483), wound (n=29) and blood (n=25). A present study were confirmed on antibiotic resistance against some pathogenic bacterial genera (n=1178) which include Escherichia coli (n=417), Staphylococcus aureus (n=377), Klebsiella pneumoniae (n=212), Pseudomonas aeruginosa (n=145) and Streptococcus spp. (n=27) isolates; was carried out in Internal Lab from Teaching Hospital in Erbil city, in September 15, 2012 to June 20, 2013. Susceptibility was determined by the disc diffusion method recommended by the Clinical and Laboratory Standard Institute (CLSI). The following antimicrobials were tested: AMC 20µg, AK (30µg), AM (30µg), AZM (15µg), ATM (30µg), CAR (100µg), CF (30µg), CEC (30µg), CFZ (15µg), CD (5µg), CFM (30µg), CPO (30µg), CP (75µg), FOX (30µg), CPR (30µg), CXM (30µg), KF (30µg), C (30µg), CN (100µg), CIP (5µg), CLM (15µg), DA (2µg), CT (10µg), E (15µg), G (10µg), GIP (5µg), IPM (10µg), DP (5µg), NAF (1µg), NF (30µg), F (300µg), NOR (10µg), OX (1µg), PG (10µg), PIP (100µg), RA (5µg), TE (30µg), TC (75µg), TOB (10µg), SXT (1.25/23.75µg), and VA (30µg). The resistances percent of all bacterial isolates show different range of resistant which start from 0.00% and reach to 100%.
