目的：探讨不同年龄段肺炎患者肺炎病原菌分布及耐药性情况。方法：选取2010年1月至2013年11月本院收治的320例肺炎患者为研究对象，将其根据年龄分为A组（＜40岁组）98例、B组（40-65岁组）105例和C组（＞65岁组）117例，然后将三组的病原菌分布情况进行统计与比较，并对所有患者主要病原菌的耐药性进行分析。结果：三组患者的革兰阴性菌检出率均高于革兰阳性菌及真菌，而A组及B组主要以肺炎链球菌检出率最高，而C组则以肺炎克雷伯菌检出率最高，且主要病原菌对氨苄西林及亚胺培南的耐药率均最高，P 均＜0．05，均有显著性差异。结论：中青年肺炎患者的病原菌主要为肺炎链球菌，老年患者则以肺炎克雷伯菌为主，且对氨苄西林及亚胺培南的耐药性最为明显。%Objective:To investigate the distribution of pathogenic bacteria and drug resistance situation of patients with pneumonia at different ages .Method:320 patients with pneumonia in our hospital from Janu-ary 2010 to November 2013 were as the study object ,and they were divided into group A (<40 years old) with 98 cases,group B(40 to 65 years old)with 105 cases and group C(>65 years old group) with 117 cases ac-cording to the ages ,then the distribution of pathogenic bacteria of three groups were analyzed and compared , the drug resistance situation of main pathogenic bacteria were analyzed .Result:The Gram-negative bacteria detection rates of three groups were all higher than those of Gram -positive bacteria and fungus , and the streptococcus pneumoniae detection rates of group A and group B the were highest ,the klebsiella pneumonia detection rate of group C was the highest ,and the drug resistance rates of main pathogenic bacteria for the ampicillin and imipenem were the highest ,all P<0.05,there were all significant differences .Conclusion:The streptococcus pneumoniae is the main pathogenic bacteria of young and middle -aged patients,and the kleb-siella pneumonia is the main pathogenic bacteria of elderly patients ,and the drug resistance situation for the ampicillin and imipenem are obvious .
