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

This research aims to examine the bacteria 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 samples, that out of a total of 194 surgeries, about 68 were Postoperative Wound Infections, with both types of bacteria, representing a percentage of 35.05. The showed diagnostic methods many typesof bacteria causing the infection, as the results showed 75 bacterial isolates individually or a mixture of isolates, where the positive isolates for Gram stain represented 31 bacterial isolates, while the negative isolates represented For Gram 44 stain, bacterial isolates showed the types of Gram-positive bacteria cells and their numbers, which included bacteria Staphylococcus aureus (MAAS) n=17, Staph aureus (MRSA) n=10, Coagulase negative staphylococci 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 aeruginosa n=9 and Acinetobacterbaumanii n=3. The showed of sensitivity The antibiotics Meropenem and Vancomycin more than effective on isolated positive bacteria while the Impenem antibiotic the effective antibiotic on isolated negative bacteria.
