ABSTRACT
Objective To explore the clinical value of one-step visualization loop-mediated isothermal amplification(LAMP)in the detection of Mycoplasma pneumoniae(Mp). Methods One-step visualized LAMP,polymerase chain reaction(PCR),and enzyme-linked immunosorbent assay(ELISA)were used to simultaneously detect 108 clinical Mp specimens in children,which included 73 cases of Mp infection diagnosed by PCR and 35 cases of other chronic/acute respiratory tract infections.On the first day of admission,one-step visualization LAMP,PCR(fluorimetric method),and ELISA were used to test the throat swab and serum sample obtained from the same patient,and the Kappa value was calculated.The consistence between LAMP and PCR and that between LAMP and ELISA were compared.On the fifth day of admission,40 patients were resampled and the findings of these three tests on the first day and on the fifth day were compared. Results One-step visualization LAMP had a sensitivity of 100% and a specificity of 94.3%,whereas ELISA had a sensitivity of 65.8% and a specificity of 82.9%.The ratio of Kappa camparing one-step visualization LAMP and PCR was 0.956 and the ratio of Kappa camparing one-step visualization LAMP and ELISA was 0.38.The number of positive specimens detected by LAMP was higher than that by ELISA on the first day. Conclusions One-step visualization LAMP has excellent sensitivity and specificity in detecting early acute Mp infection.It has high consistency with PCR and can be applied to detect Mp.
