摘要
目的:了解东莞地区住院婴幼儿急性下呼吸道感染(ALRI)的细菌学情况。方法:采用无菌吸痰管连接负压吸引器吸取1483例婴幼儿ALRI鼻咽深部的痰液,在2h内进行痰细菌培养。结果:阳性标本745份,阳性率为50.24%,其中流感嗜血杆菌192株,肺炎克雷伯菌159株,肺炎链球菌100株,表皮葡萄球菌84株,大肠埃希菌80株,金黄色葡萄球菌72株。药敏结果显示,革兰阴性杆菌对氨苄青霉素及阿莫西林耐药率较高,革兰阳性球菌对青霉素及红霉素有较高的耐药率;婴幼儿细菌性ALRI好发于夏、春季节。结论:细菌性感染在本地区ALRI中占重要地位,流感嗜血杆菌是春、夏季ALRI的主要病原体,其次是肺炎克雷伯菌、肺炎链球菌等。
Objective：To understand bacteriology of infact with acute lower respirotory infection in Dongguan. Methods：The sputum of deep nasopharynx from the 1 483 cases of acute lower respiratory tract infection was collected by aseptic in hale phlegm pipe which was connected with aspriaton of negative pressure. The samples were smeared and cultured within 2 hours. Results：There were 745 cases （50.24%） showing positive bacteria in the samples. They involved 192 strains with haemophilus influenzae,159 strains with klebsiella pneumoniae,100 strains with streptococcus pneumoniae,84 strains with staphylococcus epidermidis,80 strains with escherichia coli,72 strains with staphylococcus aureus.etc. The resistant ratic of G^-bacilli to ampicillin and amoxicillin were very high,The resistant ratie of G^ ＋ cocci to penicillin and erythromycin were very high. The incidence of bactenia acute lower respiratory tract infections in infants is higher in both summer and spring. Conclusion：Bactenia infection is the main cause of ALRI. Haemophilue influenzae is the most common bactenia pathogen of ALRI,and klebsiella pneumoniae and streptococcus pneamoniae are less common.
