摘要
目的了解南京地区社区成年健康人群鼻咽部机会致病菌携带情况。方法对南京地区社区1019例成年健康者进行非感染状态下鼻咽拭子菌种鉴定。结果鼻咽部检出率较高的机会致病菌依次为凝固酶阴性葡萄球菌、金黄色葡萄球菌、嗜血杆菌属、肺炎链球菌和肺炎克雷伯杆菌;单一菌群携带率为30.7%,复合致病菌携带率为3.4%,总携带率为34.2%;随年龄增长,金黄色葡萄球菌、嗜血杆菌属的检出率显著降低(P<0.05)。结论南京地区社区健康成年人群鼻咽部普遍存在大量凝固酶阴性葡萄球菌,同时金黄色葡萄球菌、嗜血杆菌属、肺炎链球菌和肺炎克雷伯菌等亦有较高检出率。
Objective To investigate the nasopharynx carriage status of opportunistic pathogens in non-infectious Nanjing healthy adults.Methods A total of 1019 nasopharyngeal samples from healthy adults was examined for opportunistic pathogens.Results The isolated main opportunistic pathogens with high rates were in an order of Coagulase-negative staphylococcusStaphylococcus aureusHaemophilusStreptococcus pneumoniae Klebsiella pneumonia.The isolated rate was 30.7% for single opportunistic pathogen and 3.4% for multiple opportunistic pathogens.The total carriage rate of opportunistic pathogen was 34.2%.The isolated rates of Staphylococcus aureus and Haemophilus were decreased with aging.Conclution Coagulase-negative Staphylococcus are common in non-infectious Nanjing healthy adults.The higher detection rates are Staphylococcus aureus,Haemophilus,Streptococcus pneumoniae and Klebsiella pneumonia.
