Abstract :
Background:
Surgical site infections (SSIs) are the most common nosocomial infections in surgical patients. Depending
on the source of a traumatic wound, particular pathogens are expected to be present while their prevalence varies in
different conditions. This study focused on determination of microorganisms in traumatic wound infection and the
frequency of Staphylococcus aureus and other organisms in SSIs.
Patients and methods:
A total of 116 patients were studied among whom 86 patients (18 females and 68 males)
underwent microbiological assessment for non-surgical wound infections and 30 patients (all were males) had SSIs.
Specimens were cultured on blood agar, MacConkey agar, and chocolate agar while direct examination and gramstaining
were also achieved for each sample.
Results:
Staphylococcus aureus (20.9%) was the most commonly isolated organism among non-surgical traumatic
wound infections, however, Proteus mirabilis, Salmonella Arizona and streptococcus group A were less commonly
isolated (1.1% each). Similarly, S. aureus (40%) was the most prevalent isolated organism in SSIs while enterobacter
Spp was found only in 4 cases (13.3%).
Conclusion:
Our results revealed that S. aureus is the most commonly isolated organism in non-surgical traumatic
wound infections and SSIs, therefore, appropriate therapeutic approach and applying efficient preventive modalities are
of utmost importance
