摘　　要：目的研究探讨老年呼吸道感染患者病原细菌的临床检验方法和价值。方法对2014年4月~2016年4月确诊的160例老年呼吸道感染患者的痰液标本进行培养检验和药敏试验检测。结果所有患者的痰液标本共检出革兰氏阳性菌50株（31.30%）,革兰氏阴性菌86株（53.80%）和真菌24株（15.00%）,其中革兰氏阳性菌对青霉素的耐受率为63.25%~90.37%,对万古霉素不耐受;革兰氏阴性菌对氨苄西林的耐受率为91.87%~100.00%,对头孢曲松的耐受率为43.16%~83.19%。结论老年呼吸道感染患者常见病原细菌以革兰氏阴性菌为主,其临床耐药性较高,故治疗方案中应该合理进行抗生素给药治疗,以确保患者的临床疗效和康复质量。Objective To explore and discuss the clinical testing method and value of pathogenic bacteria for elderly patients with respiratory tract infections. Methods 160 elderly patients with respiratory tract infections were regard as research object from April 2014 to April 2016 in our hospital. Their sputum specimen were cultivated for identification and antimicrobialsusceptibility test according to the CLST. Results Gram-positive bacteria were detected about 50 strains（31.30%）, and gram-negative bacteria about 86 strains（53.80%）, and fungus about 24 strains（15.00%）. Besides, tolerance rate of gram-positive bacteria to penicillin was 63.25%~90.37% and vancomycin intolerance, and tolerance rate of gram-negative bacteria to ampicillin was 91.87%~100.00% and to ceftriaxone was 43.16%~83.19%. Conclusion Gram-negative bacteria is mainly the clinical common bacterial for elderly patients with respiratory tract infections and its clinical tolerance is relative good. In order to ensure clinical efficacy and rehabilitation quality, antibiotic therapy should be arranged reasonable in the therapeutic schedule.
