Bacterial and host factors implicated in nasal carriage of methicillin-resistant Staphylococcus aureus in mice

Infect Immun. 2005 Mar;73(3):1847-51. doi: 10.1128/IAI.73.3.1847-1851.2005.

Abstract

Nasal carriage is a major risk factor for Staphylococcus aureus infection, especially for methicillin-resistant strains (MRSA). Using a mouse model of nasal carriage, we have compared several S. aureus strains and demonstrated increased colonization levels by MRSA in cystic fibrosis transmembrane conductance regulator-deficient mice and Toll-like receptor 2 (TLR2)-deficient mice but not TLR4-deficient mice.
