Characterization of Bacterial Isolates Klebsiella oxytoca from Burn Wound Infections

Burn injuries are critical due to their severity and high infection rates, contributing to substantial mortality and requiring extensive medical intervention.

Abstract

Background: Identifying bacterial pathogens causing wound infections is crucial for early diagnosis and treatment to prevent severe complications. This study aimed to characterize bacterial isolates from burn wound infections to improve diagnostic and therapeutic strategies. Methods: One hundred burn wound swabs were collected from patients admitted to two hospitals in Iraq. Swabs were cultured on nutritional and differential media to isolate bacterial pathogens. Microscopic and biochemical examinations were conducted to identify bacterial cultures. VITEK 2 Compact Automated Systems were used for Gram staining and bacterial identification. Results: Klebsiella oxytoca was the most prevalent bacterium, comprising 38% of the samples, followed by Raoultella ornithinolytica at 20%. Staphylococcus epidermidis, Kocuria kristinae, and Kocuria rosea each accounted for 14% of infections. Conclusion: Early identification of bacterial pathogens causing wound infections is essential for effective treatment. Understanding the prevalence and distribution of these pathogens can guide diagnostic and therapeutic interventions to prevent complications and improve patient outcomes.
