微生物培养及快速血清学检验对小儿肺炎支原体感染的诊断价值

Diagnostic value of microbial culture and rapid serological test for Mycoplasma pneumonia infection in children

目的对比微生物培养和快速血清学检验2种检测方法对小儿肺炎支原体(MP)感染的诊断价值。方法回顾性分析在我院确诊的144例MP感染患儿临床资料,所有患儿均接受微生物培养和快速血清学检验2种检测方法,比较2种检测方法对MP的阳性检出率、不同年龄段患儿MP的阳性检出率。结果微生物培养对MP的阳性检出率为84.03%,明显高于快速血清学检验的72.92%,差异有统计学意义(P<0.05)。2种检测方法对>4且≤8岁患儿的MP阳性检出率最高,对1岁以下幼儿的MP阳性检出率最低,对同种检测方法来说,不同年龄之间的MP阳性率比较,差异无统计学意义(P>0.05),且2种检测方法比较,差异亦无统计学意义(P>0.05)。结论微生物培养和快速血清学检验均可用于小儿MP感染的诊断,但微生物培养的检测价值更高。

Objective To comparative the diagnostic value of two detection of the microbial culture and the rapid serological test for mycoplasma pneumonia(MP)infection in children.Methods The clinical data of 144 children with MP infection in our hospital were retrospectively analyzed,and all patients received microbial culture and rapid serological test.The positive detection rate of MP,positive detection rate of MP for children of different ages were compared.Results The positive detection rate of MP with microbial culture was 84.03%,which was significantly higher than 72.92%of rapid serological test,the difference was statistically significant(P<0.05).Both of the 2 detection methods had the highest positive detection rate of MP in children from 4 to 8 years old,and had the lowest positive detection rate of MP in children less than 1 year,there was no significant difference in the positive rate of MP between different ages for the same test method(P>0.05),and there was no significant difference between the two methods(P>0.05).Conclusion Microbial culture and rapid serological test can be used for the diagnosis of MP infection in children,but the microbial culture has higher detection value.
