Bacterial profile of Infected Traumatic Wound and the Antibiogram of predominant Bacterial Isolates Using Viteck Automated System in Ramadi Teaching Hospital, Iraq.

Background: Bacterial pathogens were seen more imposed in wound infections particularly traumatic wounds . Bacterial isolates tend to show high rate of resistance against antimicrobial agents due to bacterial prolonged exposure to such antimicrobial agents in treated patients and gaining of antimicrobial resistance genetic factors and transfer between bacterial generations.
Aims of the study: This study aimed to show the bacterial profile of infected traumatic wounds and the antibiogram of the predominant bacterial isolates.
Patients and methods : Skin swabs were taken from infected wounds of (60 patients were attending Ramadi Teaching Hospital during the period of one year period (From Jan. to Dec. 2017). Bacterial investigations were done for each Specimen aseptically, bacterial isolates were diagnosed using biochemical criteria and confirmed identification was done using Vitec k2 system following. Antimicrobial sensitivity test was done for bacterial isolates using the disc diffusion test method.
Results: It was found that a higher percentage of Gram negative bacterial isolates (42) than Gram positive types (18). Staphylococcus aureus took the first rank of isolation (13) followed by psedumonas aeruginosa, proteus mirabilis and klebsiella pneumonia., (11,11,10) isolates for each respectively. All bacterial isolates showed good sensitivity to Levofloxacin, Imipenem and Carbapenem while all of them were resistant to Amoxil and Ampicillin with variable resistance ratio to other antibiotics.
In conclusion, different bacterial and antibiotic profiles were found for the isolated bacteria in addition to the high resistance rate to some antimicrobial agents so a continuous periodic study for this category is required.
