摘要
目的探讨老年呼吸道感染常见病原菌分布及其耐药性。方法采用常规痰培养方法检出病原菌,用单纸片扩散法检测药敏。结果共分离出致病菌444株,其中以革兰阴性菌为主者占总数的71.85%,革兰阳性球菌占总数的12.16%,各种致病性真菌占总数的15.99%。革兰阴性菌对亚胺培南的耐药率最低,其次为环丙沙星与阿米卡星。结论临床必须注意病原菌的检测,动态掌握常见的致病菌及细菌的变迁,合理应用抗生素,减少耐药性播散。
Objective To investigate the distribution of common pathogens of senile respiratory tract infection and drug resistance.Methods Pathogen was cultured with routine sputum and susceptibility to antimicrobial agents was studied with diffusion on Mueller Hinton medium.Results 444 strains were obtained from senile patients with respiratory tract infection.The Gram negative bacilli were the major pathogens isolated from senile patients with respiratory tract infection(71.85%) and the Gram positive bacilli accounted for 12.16%.All etiological fungus accounted for 15.99% of the pathogens.The drug resistance rate of Gram negative bacilli impenem was the lowest among cinrofloxacin and amikacin.Conclusion The pathogens should be monitored and common pathogens and bacteria changes be controlled.Appropriate use of antibiotics can decrease drug resistance.
