对６８例院内感染血液病患者的感染灶标本进行了细菌型和细菌Ｌ型培养、鉴定及药敏试验。结果表明，细菌Ｌ型的阳性率高于细菌型，两菌型均以Ｇ－杆菌为主，真菌检出率也较高；细菌型对青霉素、先锋霉素Ⅴ敏感，细菌Ｌ型对氨基甙类和第三代头孢菌素较敏感。提示对疑有医院内感染的血液病患者除作常规细菌培养外，应同时作细菌Ｌ型培养及药敏试验，以使临床用药有的放矢。
68 cases of nosocomial infection in patients with blood diseases in patients with bacterial focus and bacterial L-type culture, identification and drug sensitivity test. The results showed that the positive rate of bacterial L-type was higher than that of the bacterial type, the two bacterial types were mainly G-bacilli, and the fungal detection rate was also higher. The bacterial type was sensitive to penicillin and cephalosporin V, Classes and third-generation cephalosporins are more sensitive. Prompt suspected of hospital infection in patients with blood diseases in addition to conventional bacterial culture should be at the same time for bacterial L-type culture and susceptibility testing to make the clinical medication targeted.
