对１９９６ 年至１９９７ 年本院３２５ 份普通痰细菌培养和药物敏感试验结果进行分析研究。结果：阳性痰细菌分离率为２５７％ 。Ｇ－ 杆菌占首位（５７６％ ，５８１％ ），其中铜绿假单胞菌、肠杆菌属、大肠杆菌和克雷伯杆菌为优势菌；Ｇ＋ 球菌占第二位（３７０％ ，２４４％ ），其中金葡菌居多。大部分Ｇ－ 杆菌对喹诺酮类、头孢霉素三代及丁胺卡那霉毒有较好的敏感性。金葡菌对头孢哌酮、丁胺卡那霉素和新霉素较敏感。结论：Ｇ－ 杆菌感染仍占首位，普通痰细菌培养仍为主要方法，传统抗生素如新霉素、丁胺卡那霉素和万古霉素应受重视 In 1996 to 1997, our hospital 325 sputum bacterial culture and drug sensitivity test results were analyzed. Results: The positive sputum bacterial separation rate was 25.7%. G- bacillus accounted for the first place (57.6%, 58.1%), of which Pseudomonas aeruginosa, Enterobacter, Escherichia coli and Klebsiella were dominant bacteria; G + cocci accounted for the second place (37.0% , 244%), of which Staphylococcus aureus is mostly. Most of the G-bacilli have good sensitivity to quinolones, three generations of cephalosporins and amikacin. Staphylococcus aureus is more sensitive to cefoperazone, amikacin and neomycin. CONCLUSIONS: G-bacilli infection still accounts for the first place, and common sputum bacterial culture is still the main method. Traditional antibiotics such as neomycin, amikacin and vancomycin should be emphasized
