ABSTRACT
Objective To compare the sensitivity and specificity of dot immunogold method (DIM) and particle agglutination (PA) for the diagnosis of mycoplasma pneumoniae (MP) infection. Methods The 190 serum specimens of 113 children with mycoplasmal pneumonia (infection group) and 50 serum specimens of 50 health children (health group) were tested for MP by PA and DIM- A and B. Results In infection group, the positive rates of DIM- A and B were 82.63% (157/190) and 84.74%(161/190), and there was no statistical difference (χ2 = 0.31, P>0.05); the positive rate of PA (titer ≥1160) was 70.00%(133/190), the positive rate of PA was significantly lower than that in DIM-A and B, and there were statistical differences (P0.05); the positive of PA was 8.00% (4/50), the positive rate of PA was significantly lower than that in DIM- A and B, and there were statistical differences (P<0.05 or<0.01). Conclusions Compared with the PA, DIM has low sensitivity and poor specificity for clinical diagnosis. DIM is not suitable for clinical diagnosis of MP infection.
