【摘要】 本文用定量法对31例正常人和24例儿童进行了菌群分析。成人组表葡(表皮葡萄球菌)分离率为100%,类白喉(类白喉杆菌)为90.3～100%,为皮肤及鼻孔的优势菌。鼻孔 G~-杆菌(革兰氏阴性杆菌)为48.4%,金葡(金黄色葡萄球菌)为22.6%。皮肤金葡、G~-杆菌和真菌均在10%以下。儿童组皮肤和鼻孔的优势菌亦为表葡(62.5～87.5%)和类白喉(58.3～75%),且皮肤金葡分离率亦较高(16.7～29.2%),未分离到真菌和 G~-杆菌。成人组前额、鼻孔表葡和类白喉菌密度,经相关性检验,呈正相关关系(P 分别为<0.005和<0.05),此一现象尚未见有人提及。不同部位的皮肤菌群亦异,成人前额表葡和类白喉密度均大于前臂,鼻孔 G~-杆菌和金葡分离率高于皮肤,因而检测时应取3个以上部位标本为宜。更多还原

【Abstract】 This study investigated the microbial flora of anterior nares and skin of forehead and forearm of 31 healthy adults and 24 chil- dren by using qualitative methods.The car- riage rate of S.epidermidis was 100% and the diphtheroids were 90.3—100%,these two bacterial Spp.are predominant organisms in the anterior nares and on the skin in adult. Higher incidence of Gram-negative rod(48.4%) and S.aureus(22.6%)was detected in the nare.The incidence of fungi,S.aureus and Gram-nagative rod on the skin was below 10%.S.epidermidis and diphtheroid were also found to he the resisdent skin organisms of cbildren.Higher carriage rate of S.aureus of skin was observed in this group whereas Gram negative rod and fungi were not dete- cted.Positive correlation between the S. epidermis and diphtheroids existed in the anterior nares and on the skin of forehead in adults. Difference of the skin flora exis- ted at different sites in the group.Therefore it was suggested that the samples should be taken at last from 3 sites or more.更多还原
