一年间共培养标本1355份，培养出病原菌（不含真菌）355株，阳性率26．2％。革兰氏阳性球菌与革兰氏阴性杆菌之比为49．2％（117／238）。金黄色葡萄球菌、克雷伯氏菌属、大肠埃希氏菌以及铜绿假单胞菌等仍是医院感染的优势菌。355株病原菌来自血液、尿液、痰、粪、脓及各种分泌物标本。药敏试验结果表明：常见病原菌对青霉素、红霉素、氨苄青霉素等的耐药率＞50％；对庆大霉素的耐药率在20─40％之间；对氟哌酸（大肠埃希氏菌除外）的耐药率＜25％；对丁胺卡那霉素的耐药率＜15％。
A total of 1355 specimens were cultured in one year, and 355 strains of pathogens (without fungi) were cultivated, with a positive rate of 26.2%. The ratio of gram-positive cocci to gram-negative bacilli was 49.2% (117/238). Staphylococcus aureus, Klebsiella, Escherichia coli, and Pseudomonas aeruginosa are still dominant bacteria in nosocomial infections. 355 strains of pathogens were from blood, urine, sputum, feces, pus, and various secretion specimens. Drug susceptibility test results showed that common pathogens were resistant to penicillin, erythromycin, ampicillin, etc. >50%; gentamicin resistance rate was between 20 and 40%; and norfloxacin (Escherichia coli Resistant rates of H. pastoris were <25%; and the resistance to amikacin was <15%.
