Triclosan Promotes Staphylococcus aureus Nasal Colonization

An interesting paper in the journal mBio features research that indicates that triclosan is commonly found in the nasal secretions of healthy adults and that the presence of triclosan trends positively with nasal colonization by S. aureus. The researchers demonstrate that triclosan can promote the binding of S. aureus to host proteins such as collagen, fibronectin, and keratin, as well as inanimate surfaces such as plastic and glass. In addition, the research shows that triclosan-exposed rats are more susceptible to nasal colonization with S. aureus. The biocide triclosan is used in many personal care products, including toothpastes, soaps, clothing, and medical equipment. The paper raises questions over the continued application of the product.
