感染早期行快速肺炎支原体培养探讨

Quick culturing mycoplasma pneumoniae during early infection

目的探讨感染早期行快速肺炎支原体培养对提高诊断肺炎支原体阳性率的作用。方法选取在2014年6—12月,我院收治的600例疑似肺炎支原体感染的儿童患者为研究对象,随机分成研究组和对照组,各300例。研究组在发病的3 d内进行快速肺炎支原体培养,并于4 d的治疗后行肺炎支原体抗体的检测;对照组在发病的3 d后进行快速肺炎支原体培养,并在满1 w的治疗后行肺炎支原体抗体的检测。结果研究组患者阳性检出率为39.7%,阴性检出率为60.3%;对照组患者阳性检出率为32.0%,阴性检出率为68.0%。两组差异具有统计学意义(P<0.05)。结论在患者感染的早期行快速肺炎支原体培养,能够比较准确地提高肺炎支原体阳性的检出率和药敏的结果。

Objective To investigate the role of quick culturing mycoplasma pneumonia in improving the positive rate of diagnosis of mycoplasma pneumoniae during earlyinfection. Methods Selected600 cases of children patients who were suspected pneumonia mycoplasma infection during June2014 and December2014 in our hospital as the research object,they were randomly divided into study group and control group,300 cases in each group. Rapid culture of mycoplasma pneumonia was done in 3 days after infection in research group,and testing Mycoplasma pneumoniae antibody 4 days after treatment,however,mycoplasma pneumonia antibody was detected one week after the treatment in control group. Results In research group,the positive rate was 39. 7%and the negative rate is 60. 3%. And in the control group,the positive rate was 32. 0% andthe negative rate was68. 0%. The differences between the two groups was statistically significant（ P〈0. 05）. Conclusions Rapid culture of mycoplasma pneumonia during the early days of infectioncan accurately improve Mycoplasma positive rate and drug sensitivity results.
