了解住院患者假单胞菌属下呼吸道感染的临床特点及药敏。方法 做细胞培养及鉴定并以纸片法(Kirby-Bauer法)测定该菌的体外药物敏感性。 结果 同期在131株假单胞菌中,铜绿假单胞菌72株,恶臭假单胞菌36株。伴混和茵42.5％,混和菌主要为大肠埃希氏菌,阴沟肠杆菌。药敏提示假单胞菌呈多重耐药。结论 该菌有较低的营养要求及对大多数抗菌药物耐药,所以应用抗菌药物因人、因时、因地而异。细菌培养及药敏结果不容忽视。 To understand the clinical characteristics and susceptibility of lower respiratory tract infection in patients with Pseudomonas. Methods Cell culture and identification were performed and in vitro drug sensitivity of the strain was determined by Kirby-Bauer method. Results Among the 131 Pseudomonas strains, 72 strains were Pseudomonas aeruginosa and 36 strains were Pseudomonas putida. With mixed and Yin 42.5%, the main mixed bacteria Escherichia coli, Enterobacter cloacae. Drug-sensitive Pseudomonas showed multiple drug resistance. Conclusion The bacteria have lower nutritional requirements and resistance to most antibacterial drugs, so the application of antibacterial drugs due to human, due to the time, vary from place to place. Bacterial culture and drug susceptibility results can not be ignored.
