Abstract

Nosocomial infection represents a major problem in health care facilities, resulting in prolonged hospital stays, substantial morbidity and mortality. Aim of study: This study aimed to determine types of bacteria that cause infection in burn wounds of patients admitted to Benghazi hospitals. Methods: Standard biochemical tests and Standard Kirby- Bauer method were used for identification and sensitivity profile determination. Results: 67% of pathogens infected burn wounds was belong to Gram-negative bacteria and 33% was belong to Gram-positive bacteria. Gram-negative bacteria showed higher incidence in ICU (60%) compared with department of burs unit, while Gram-positive bacteria showed lower incidence (30%). Prevalence of Pseudomonas aeruginosa (50%) and Staphylococcus aureus (20%) was higher in burned patient with no chronic disease compared with chronic diabetic and leukemic patients. Conclusion: This study conclude that the burn wounds of patients admitted to burn department and intensive care units in Benghazi hospitals were infected with both Gram-negative and Gram-positive bacteria, that showed variable sensitivity profile. Pseudomonas aeruginosa is the highest in occurrence in this study followed by Staphylococcus aureus.
