浅析下呼吸道感染病原菌及其耐药性

摘要

目的对下呼吸道感染患者病原菌的情况及其耐药性进行分析，为临床合理用药提供指导和依据。方法选取100例下呼吸道感染患者的痰液标本进行分析，对被感染部位病原菌进行分离鉴定。结果分离出病原菌130株，其中革兰阴性菌为69株(β内酰胺类耐药率最高)，革兰阳性61株(大环内酯耐药率最高)。结论病原菌对使用频率高的抗生素有较强耐药性，应依据药敏试验结果合理使用抗生素，提高临床治愈率。%Objective The situation of the pathogenic bacteria and their drug resistance in patients with lower respiratory tract infections were analyzed, and provide guidance and basis for clinical rational drug use.Methods Select 100 cases of lower respiratory tract infection in patients with sputum specimens were analyzed, and the separate identification of the pathogen infected parts.Results 130 strains pathogenic bacteria isolated, of which the gram-negative bacteria of 69 strains (beta lactam, highest percentages), 61 strains gram-positive (large ring lactone, the highest percentages).Conclusion Pathogenic bacteria have stronger resistance to high frequency use antibiotics, should according to the results of drug sensitive test, reasonable use of antibiotics, improve the clinical cure rate.
