Patients who carry nasal methicillin-resistant (MRSA) may also harbour MRSA in the oro-pharyngeal cavity. However, the naso-oro-pharyngeal co-carriage is infrequently assessed. The incidence of concurrent MRSA carriage of the naso-oro-pharynx was ascertained, and the sensitivity of two methods, a throat swab and a phosphate buffered saline (PBS) oral rinse, for MRSA detection was investigated. Among nasal MRSA carriers, 80% harboured MRSA in the oro-pharynx. Among these patients, 15% had MRSA detected in the oro-pharynx and not in the throat. Oro-pharyngeal colonisation represents a significant reservoir to persistence as well as nasal recolonisation. Decolonisation methods effective in reducing oro-pharyngeal MRSA in addition to nasal carriage should be investigated.
携带耐甲氧西林金黄色葡萄球菌（MRSA）的患者，其口咽腔也可能存在MRSA。然而，鼻-口咽共同携带情况很少得到评估。本研究确定了鼻-口咽同时携带MRSA的发生率，并研究了两种检测MRSA方法（咽拭子和磷酸盐缓冲盐水（PBS）口腔冲洗）的敏感性。在鼻MRSA携带者中，80%的患者口咽部存在MRSA。在这些患者中，15%的患者口咽部检测到MRSA，而咽喉部未检测到。口咽部定植是持续感染以及鼻腔重新定植的重要储存库。除鼻腔携带外，还应研究有效减少口咽部MRSA的去定植方法。
