Abstract
Most of considerable morbidity and mortality that attends major burn injury is the result, directly or indirectly of infection of burn wounds by bacteria and fungi. Similarly, morbidity in patients with smaller burns is also largely related to infection. Like any other microbial infection, microorganisms that colonize the burn may originate either from the patient (endogenous) or from the environment (exogenous) P. aeruginosa and other gram negative bacteria are often the main infecting bacterial species C. albicans and Aspergillus spices are the main infecting fungal spices.
Evidence accumulating from literature is that the incidence of P. aeruginiosa infection are increasing. This organism grows well in most environment, including the burn wounds, and resistant to most commonly used antibiotics. There is also increase in the incidence of fungal infection.
Burn wounds represent excellent culture media for bacteria and fungi because thermal injury occur as a result of denaturation of cell protein, interference with cell metabolism and secondary interference with vascular supply.
The burn wounds are classified into 1st , 2nd and 3rd degree burn wounds or according to percent of the burned area from the total body areas (%TBSA) .
