Abstract EN
Background.
Extensive studies have focused on the diagnosis and treatment of Mycoplasma pneumoniae infection; however, rare studies investigated the posttreatment conditions.
We analyzed the carrying status of M.
pneumoniae in the respiratory tract of children before and after treatment.
Methods.
Ninety-two children with M.
pneumoniae pneumonia were included in this study.
Clinical data were obtained from each patient, and pharyngeal swab sampling was performed at preliminary diagnosis and discharge.
Real-time PCR and dilution quantitative culture were utilized to determine the DNA quantification and number of viable M.
pneumoniae from samples collected upon preliminary diagnosis and discharge.
Results.
All the 92 cases showed DNA positivity upon preliminary diagnosis, serum IgM antibody was detected in 80 patients, and positivity of M.
pneumoniae culture was observed in 82 cases.
Upon discharge, the M.
pneumoniae nucleotide and culture positivity were detected in 87 and 49 cases, respectively.
The content of viable M.
pneumoniae was 10–104 CCU/mL and 10–102 CCU/mL in the preliminary diagnosis samples and discharge samples, respectively.
Conclusions.
Real-time PCR was rapid and effective for the qualitative diagnosis of M.
pneumoniae at the early stage, but it cannot be used to evaluate the prognosis of patients with M.
pneumoniae infection.
Quantitative analysis for M.
pneumoniae DNA could not directly reflex the viable strain content.
