Abstract

Objectives: Resistance of antimicrobials by different pathogens is a dangerous problem in developing countries. Therefore we design this study to identify the most prevalent pathogenic bacteria that cause different infections in Al-Kufa Central Hospital – Iraq and determine the antibiotic susceptibility patterns of these pathogens. Methods: Five hundred and seventeen bacterial strains were isolated from different infections (urinary tract infections 171, burns infections 238, respiratory tract infection 55 and blood infection 53). Eleven antimicrobials disc were used to determine the antimicrobial sensitivity by disc diffusion method. Results: Pseudomonas aeruginosa was the most predominate bacteria (122 isolates) followed by K. Pneumoniae (96 isolates), E.coli (64 isolates), S. pyogenes (59 isolates), S. aureus (51 isolates), S. pneumoniae (48 isolates), Proteus. spp. (47 isolates) and Salmonella spp. (14 isolates). All bacterial strains were highly resistant to most antimicrobials with percentage between 90% to 100%.There were 459 bacterial strains (91.61%) were multidrug resistant. Conclusions: This study proved that the predominant bacteria of burns infections and urinary tract infections were P. aeruginosa followed by K. Pneumoniae. Gentamicin, Amikacin and Ciprofloxacin are a drug of choice for treatment of these infections.
