Application of rapid culture and passive particle agglutination for mycoplasma pneumonia in children

Objective To explore the significance of applying rapid culture(RC) and passive particle agglutination(PPA) in children with mycoplasma pneumonia(MP).Methods MP in 114 children with pneumonia within 5 days of the disease course was examined with RC and PPA.According to clinical diagnosis,the children were divided into 2 groups of mycoplasma pneumoniae pneumonia(group A,54 cases) and non-mycoplasma pneumoniae pneumonia(group B,60 cases).MP in group A was rechecked by these two methods between 7 to 10 days of the disease course and positive rates were compared.Results The results of RC and PPA examinations within 5 days of the disease in 114 cases showed that the positive rates of MP were 42.1% and 23.7%,the sensitivities were 83.33% and 50.0%,the specificities were 95.0% and 100%,the areas under ROC curve were 89.2% and 75.0%,respectively(P0.05).The positive rates of RC and PPA examinations between 7 to 10 days of the disease in group A were 64.81% and 100.0%,respectively(P0.05).ConclusionExaminations of MP with RC and PPA methods are of importance in diagnosis of mycoplasma pneumoniae pneumonia when selecting the reasonable time of examination.
