The study of Antibiotics Resistance for Isolates isolated of Postoperative Wound Infections in some Hospitals Baghdad City1

Abstract

This research aims to examine the bac-teria causing infection at the surgical site and their susceptibility antibiotics. The Surgical site infection samples were taken from sixty eight patients suffering with infections after various operations with the ages included in the study were between (15-64) years old for both sexes. the results of the current study showed, during the mentioned time period for collecting sam-ples, that out of a total of 194 surgeries, about 68 were Postoperative Wound Infections, with both types of bacteria, representing a percent-age of 35.05.the showed diagnostic methods many typesof bacteria causing the infection, as the results showed 75 bacterial isolates individ-ually or a mixture of isolates, where the positive isolates for Gram stain represented 31 bacterial isolates, while the negative isolates represent-ed For Gram 44 stain, bacterial isolates showed the types of Gram-positive bacteria cells and their numbers, which included bacteria Staph-ylococcus aureus (MAAS) n=17 , Staph aureus (MRSA) n=10 , Coagulase negative staphylo-cocci n=3 and Streptopyogenes n=1 ,While the types of Gram-negative bacteria cells and their numbers, which included bacteria E.coli n=23 , Klebsellia species n=9 , Pseudomonas aerugi-nosa n=9 and Acinetobacterbaumanii n=3. the showed of sensitivity The antibiotics Meropen-em and Vancomycin more than effective on iso-lated positive bacteria while the Impenem antibi-otic the effective antibiotic on isolated negative bacteria.
