流感嗜血菌

结论我们研究的儿童上呼吸道携带流感嗜血菌对氨苄西林耐药的机制主要是TEM-1型β内酰胺酶的产生。

Conclusions TEM-1 β - lactamase is the principal mechanism of ampicillin resistance of H.influenzae isolates from the upper respiratory tract of children .

结果24、48h，细菌在Copan运送系统上的菌量及存活率明显高于无菌棉拭子，苛氧菌（流感嗜血菌和肺炎链球菌）24、48h在无菌棉拭子上不生长；

RESULTS The quantity and liability of bacteria on Copan delivery system were higher than those on sterile cotton delivery system significantly at 24 h or 48 h , respectively . Fastidious organisms ( H.influenzae and S.pneumoniae ) hardly grew on sterile cotton at 24 h and 48h .

结果该地区儿童肺炎链球菌和流感嗜血菌携带率分别是34.5%和26.8%；

Results The detection rate of Sp and Hi was 34.5 % and 26.8 % respectively .

G+菌对青霉素和苯唑西林耐药率高，副流感嗜血菌对多种常用抗菌药物耐药；

The rate of drug resistance of G ~ + bacteria is high , and H.parainfluenzae is multidrug ( resistant );

方法对肾内科<37d出现10例陆续发生的副流感嗜血菌感染进行流行病学调查，对28例医务人员进行咽拭子培养。

METHODS Ten cases of infection by H. parainfluenzae that arised in succession during 37 days in the department of nephrology of our hospital were investigated .

副流感嗜血菌占分离菌株的56.57%，金黄色葡萄球菌占20.2%，肺炎克雷伯菌占10.1%，表皮葡萄球菌占7.07%；

The strains of Haemophilus parainfluenzae , Staphylococcus aureus , Klebsiella pneumoniae , and S.epidermidis were 56.57 % , 20.2 % , 10.1 % , and 7.07 % , respectively ;

副流感嗜血菌对哌拉西林、头孢唑林、头孢哌酮和庆大霉素耐药率为100.0%，对阿米卡星耐药率达98.2%。

The rate of drug resistance of H.parainfluenzae to piperacillin , cefazolin , cefoperazone , and ( gentamicin ) were all 100 % , and to amikacin was 98.2 % .

方法采用专用巧克力和血平板培养基对采集的400名3~5岁儿童鼻咽分泌物培养并鉴定，对鉴定明确的肺炎链球菌和流感嗜血菌进行不同抗生素检测。

Methods Four hundred samples of rhinopharynx secretion from children 3 ~ 5 years old were cultured with special chocolate and blood medium plate . Sp and Hi isolated were tested for antibiotic susceptibility .
