The researchers were curious about this microbe after comparing the nasal microbiota of people with and without S. aureus.

在比较了有和没有金黄色葡萄球菌的人的鼻腔微生物群后，研究人员对这种微生物感到好奇。

Poor oral hygiene can increase colonisation with pathogens such as S. aureus or P. aeruginosa that can be aspirated into the lower airway, thus increasing the risk of pneumonia.

不良的口腔卫生会增加致病菌的定植，如金黄色葡萄球菌、铜绿假单胞菌等；这些致病菌会被吸入下呼吸道，从而增加罹患肺炎的风险。

They found that people who had S. lugdunensis in their noses were nearly six times less likely to also have S. aureus up there.

他们发现鼻子里有路邓葡萄球菌的人鼻子里也有金黄色葡萄球菌的可能性要低近六倍。
