老年下吸呼道感染卡他布拉汉菌的检测及药敏分析

Examination and Susceptibility Test of Branhamella Catarrhalis in Lower Respiratory Tract Infection or Elder Patients

探讨卡他布拉汉菌在引起老年下呼吸道感染中的临床意义并进行药敏分析。方法：回顾调查１９９７年１～１２月我院内科老年下呼吸道感染患者痰或咽拭卡他布拉汉菌培养及药敏试验资料。结果；８７例老年患者中，卡他布拉汉菌阳性５５例（占６３．２％），５５例中，合并混合菌感染２２例。药敏试验结果：大多数卡他布拉汉菌阳性患者对丁胺卡那霉素、卡那霉素、庆大霉素、头孢唑啉、氟哌酸均敏感，而对青霉素、氨苄青霉素、红霉素则呈耐药。结论：加强临床卡他布拉汉菌的检测及药敏试验，根据药敏试验选用有效抗生素，以减少耐药菌株的产生和预防医院内感染。

In order to investigate the clinical value of the examination and susceptibility test of B. Catarrhlis in lower respiratory tract infection of elder Patients, a retrospective analysis of B. Catarrhalis culture and susceptibility test inpatients with lower respiratory tract infection in our hospital and been observed from Jan, 1997 to Dec, 1997. Incatarrhalis culture of samples of 87 elder patients, 55 (63. 2 % ) showed catarrhalis positive results. Among them,22 combined other bacteria infection. The results of susceptibility test showed that most of patients withcatarrhalis infection were sensitive to amikacin, kanamycin, gentamycin, cefazolin, norfloxacin and resistant topenicilin, ampicillin and erythromylin. So in order to reduce the ratio of drug resistance bacteria and protectagainst hospital infection, the effective antibiotic must be choiced based on the result of susceptible test.
