Abstract

The adherence of bacterial pathogens to wounded skin is probably the first step in wound infection. This report describes the development of a bioassay to simulate the adherence of bacteria to wounds. The adherence of bacteria was examined by exposing wounds to known quantities of pathogens, washing the wounds with distilled water, and quantitating the number of adherent bacteria per cm2 of tissue. Our studies focused on the effects of naturally occurring mediators of bacterial adherence, such as wound fluid, serum, and fibronectin. Bacterial adherence was shown to be challenge dependent. Addition of wound fluid, serum, and heat-inactivated serum was shown to reduce the adherence of Pseudomonas aeruginosa to the wound surface compared with that of a saline control. Additional fibronectin treatment of the wound had no effect on the adherence of Staphylococcus aureus. The ability to identify what affects the binding of bacteria to wounded skin can lead to a better understanding of wound infection.
