[Clinical study on cross-infection of mycoplasma pneumoniae and other viruses in children].

OBJECTIVE

To investigate the clinical cross infections of mycoplasma pneumoniae (MP) and other viruses in children, providing a reference for the diagnosis and treatment of respiratory disease.

METHODS

Serum specimens of the children hospitalized with fever, respiratory symptom besides positive results of MP-Ab IgM detection were collected. And several common viruses popular in children were investigated within the specimens collected by ELISA kits or indirect immunofluorescence.

RESULTS

(1) The PCT levels of 385 cases (81.7%) appear to be under 0.5 ng/ml. (2) In the 514 cases detected for Cox-IgG and Cox-IgM, the positive rates are respectively 40.3% and 35.6%. (3) 2 cases (0.8%) appear to be influenza B virus positive. And the positive rates of parainfluenza virus 1, 2 and 3 are 0.8%, 0, and 9%. 4, 84 cases (11.8%) are positive for EB-IgM and 451 cases (63.6%) positive for EB-IgG.

CONCLUSION

Cross infections rarely occur between MP and common respiratory viruses in Children. The cross-infection rate between Cox-virus and MP is up to 35.6%.
