摘　　要：目的:了解下呼吸道感染主要致病菌及药物敏感性,为合理使用抗生素提供依据。方法:对住院患者采集咽拭子标本310份,其中涂片染色镜检,其中300份咽分泌物标本进行病原学鉴定,并做药敏试验。结果:下呼吸道以G+细菌占首位,以肺炎链球菌为主,药物敏感试验结果显示,头孢曲松钠对G+细菌有效率达87%。鉴定出的G+菌对头孢菌素类,喹诺酮类敏感,对青霉素耐药。结论:肺炎链球菌是小儿下呼吸道感染主要致病菌,头孢曲松钠是治疗下呼吸道感染的有效抗生素。Objective： The study of the main pathogenic bacteria and sensitivity to antibiotics of lower respiratory tract infection.To provide the bacteriological index for using antibiotics in treating the lower respiratory tract infection reasonably.Methods：Total 310 sputum spceimeus were collected, and there were 300 specimens from the lower respiratory tract indentified by microscopy. All the 300 spumum specimens were cultured for pathogenic assay and antibiotics sensitivity test.Results-G^＋ bacteria were the most bacteria in the lower respiratory tract identified,most of the streptococcus bacillus G^＋ bacteria were sensitive to impienem for cefftrixone（87% ）.The result of antibiotics sensitivity test G^＋ bacteria were identified to be sensitive to ceftrixone and ofloxacin but resistant to penicilline. Conclusion： The streptococcus bacillus are most important bacteria in patients of lower respiratory tract identified. The ceftrixone are effctive antibiotics for treating acquired pneumonia.
