| Objective To analyze the distribution characteristics of mycoplasma pneumoniae (MP) infection in those children with respiratory tract infections, and provide reliable evidence for clinical prevention and treatment. Methods The clinical data of 380 children with respiratory tract infections ever treated in our hospital between Jan 2017 and Dec were retrospectively analyzed. After MP-IgM detection in all children by indirect immunofluorescence assay, the positive rate of MP in these children and the distribution features of age, gender and season in the infected children were then calculated and analyzed. Results Among the 380 cases with respiratory tract infections, 148 cases were found to be MP-IgM positive and the positive rate of MP was 38.95%. Meanwhile, the positive rate of 44.86% in girls was significantly higher than the positive rate of 31.33% in boys (P<0.05). Among those MP infected children, the highest positive rate of 58.54% was found in preschool children, and the lowest positive rate of 8.33% was found in infants, with significant difference between them (P<0.05). The positive rate of MP in spring and summer was significantly higher than that in autumn and winter (P<0.05), in which the positive rates of 58.53% in May being the highest. Conclusions MP has been the important pathogen of respiratory tract infections in children. In respiratory tract infections, the MP infection would be more common in girls, in preschool children, and in spring and summer. |
