Epidemiology and risk factors of nasal carriage of Staphylococcus aureus CC398 in two distinct cohorts in France

The epidemiology of methicillin-resistant S. aureus CC398 is known to be mostly linked to livestock, whereas the epidemiology and risk factors of methicillin-susceptible S. aureus CC398 is not well known. We aimed to determine the prevalence of nasal carriage of S. aureus CC398 in the community and among hospitalized patients and to evaluate the factors associated with carriage.

耐甲氧西林金黄色葡萄球菌CC398（methicillin-resistant S. aureus CC398）的流行病学特征已被证实多与畜禽养殖业相关，而甲氧西林敏感型金黄色葡萄球菌CC398（methicillin-susceptible S. aureus CC398）的流行病学规律及相关危险因素目前仍未得到充分阐明。本研究旨在明确社区人群与住院患者中金黄色葡萄球菌CC398（S. aureus CC398）的鼻腔定植率，并评估与其定植相关的影响因素。
