摘　　要：目的了解医院获得性肺炎(HAP)病原菌的分布及耐药情况,探讨行之有效的预防对策。方法将192例HAP患者的痰标本进行细菌分离、鉴定和药敏试验。结果分离出的167株病原菌中包括69株革兰阴性杆菌、58株真菌、40株革兰阳性球菌,分别占41.3%、34.7%、24.0%;革兰阳性球菌的耐药性最高,革兰阴性杆菌耐药率较低,真菌对抗真菌药物敏感。结论在医院获得性肺炎中,革兰阴性杆菌是主要的病原菌,真菌引起的感染高于革兰阳性球菌引起的感染;革兰阳性球菌耐药情况严重。OBJECTIVE To investigate the distribution and drug resistance of pathogens in nosocomial pulmonary acquired infection（HAP）,and inquire into effective countermeasures.METHODS Bacterial isolation,identification and drug sensitivity test were performed to 192 sputum specimens from patients with HAP.RESULTS A total of 176 strains of pathogens included 69（39.2%） G-bacilli,58 fungi（33%） and 40 G＋ cocci（22.7%）.The drug resistance of G＋ cocci was highest,the drug resistance of G-bacilli was lower,fungi were sensitive to antifungal drugs.CONCLUSION G-bacilli are the main pathogens in HAP.The infection caused by fungi is more than that caused by G＋ cocci,but the drug resistance of G＋ cocci is serious.
