Abstract:
Objective
To analyze the distribution characteristics of Mycoplasma pneumoniae, Chlamydia pneumoniae and Legionella pneumophila in 100 hospitalized children with acute respiratory infection.
Methods
A total of 100 children with acute respiratory infection admitted to Respiratory Department of Hunan Children's Hospital from January 2014 to January 2016 were selected as the research objects. The detection situation of Mycoplasma pneumoniae, Chlamydia pneumoniae, Legionella was summarized in different genders, different years of age and different seasons.
Results
Among the 100 children with acute respiratory tract infection, there was 35 cases of Mycoplasma pneumoniae, 22 cases of Chlamydia pneumoniae and 10 cases of Leginella pneumophila, and there were 33 cases of other pathogens. There was no statistical difference in the detection rate of Mycoplasma pneumoniae and Chlamydia pneumoniae between different genders(P>0.05). The defection rate of Chlamydia pneumoniae in boys was significantly lower than in girls, the difference being statistical(P<0.05).There was statistical difference in the age distribution of Mycoplasma pneumoniae(P<0.05), but no difference in Chlamydia pneumoniae or Legionella pneumophila(P>0.05). There was no statistical difference in the season distribution of all the three pathogens(P>0.05).
Conclusion
Mycoplasma pneumoniae, Chlamydia pneumoniae and Legionella pneumophila are important pathogens of acute respiratory tract infection, which should arouse clinical attention.
