老年呼吸道感染者的病原体细菌培养检验方法研究

摘要

Objective To study the clinical test of pathogenic bacteria in elderly patients with respiratory tract infection. Methods Sputum of 191 cases of elderly patients with respiratory tract infection were tested by bacterial culture. Results 191 samples were tested and 184 strains were isolated with 96.34%positive rates,the pathogens were gram negative bacteria(55.43%)and gram positive bacteria(35.33%),fungi(13.04%),the resistance was higher in gram negative bacteria to ampicil in,and it was higher in gram positive bacteria to penicil in. Conclusion Gram negative bacteria is the main pathogenic bacteria in elderly patients with respiratory tract infection,the most efficient test method is should choosed,strengthen quality control.%目的：探讨老年呼吸道感染者的病原体细菌培养检验方法。方法选择191例老年呼吸道感染患者的痰液进行细菌培养检验。结果检测191份标本，分离阳性菌株184份，阳性率为96.34%，其中革兰阴性菌占55.43%，革兰阳性菌占35.33%，真菌占13.04%。革兰阴性菌对氨苄西林的耐药性较高，革兰阳性菌对青霉素耐药率较高。结论老年呼吸道感染者的病原体主要为革兰阴性菌，应选择有效的检测方法，加强质量控制。
