Abstract: BACKGROUND: The methods for testing the bacterial barrier properties of medical wound dressings are available; however, the ability of medical wound dressings to resist penetration of bloodborne pathogens still needs further study.
OBJECTIVE: To investigate the ability of four kinds of wound dressings to resist penetration of bloodborne pathogens by simulating clinical conditions.
METHODS: The abilities of four kinds of wet-to-dry wound dressings (nonwoven, film, polyurethane foam, and hydrocolloid dressings) to resist penetration of bloodborne pathogens were tested using Phi-X174 Bacteriophage Penetration Test System. 
RESULTS AND CONCLUSION: (1) The nonwoven dressing had plaques formed by the penetration of phage Phi-X174, however, the film, polyurethane foam, and hydrocolloid dressings did not have plaques formed by the penetration of phage Phi-X174. (2) These results suggest that the film, polyurethane foam, and hydrocolloid dressings, but not the nonwoven dressing have the ability to resist penetration of bloodborne pathogens.

Key words: medical wound dressings, bloodborne pathogens, penetration, phage, plaques
