Chronic wound infection: facts and controversies.
Chronic wound infections are responsible for considerable morbidity and significantly contribute to the escalation in the cost of health care. Wound infection may initially be manifest as bacterial colonization, and it is only when colonization is combined with other factors, such as decreased vascular supply, intrinsic virulence of specific bacteria (eg, Staphylococcus aureus), and host immune factors, that true infection occurs. The microbiology of chronic wounds is complex, and it is difficult to discern which bacteria are culpable. Deep cultures or quantitative biopsies of wound tissue may be necessary. In some instances, such as in the presence of certain mycobacteria, isolation of specific organisms confirms causation. In many instances, it is appropriate to treat these wounds empirically with a combination of topical antiseptics and systemic antibiotics, especially in the presence of invasive infections.
