Abstract
Objective:To analyze the bacterial etiology distribution of children with community-acquired pneumonia(CAP) in Longquanyi district, providing powerful laboratory basis for the rational use of antibiotics.Method:Eight hundred and eighty-five children with CAP admitted to our department from January 2014 to October 2015 were selected as the objects,the respiratory secretions of all patients were taken for general bacteria culture on the day of admission, the bacteria of sputum culture were then identified.Result:In the 885 children with CAP,the positive etiology detection was 372 cases(42.03%),including 180 strains of gram-positive bacteria,which accounting for 48.39%,and 192 strains of gram-negative bacteria,which accounting for 51.61%.Gram-positive bacteria were mainly for 145 strains(38.98%) of streptococcus pneumoniae and 32 strains(8.60%) of staphylococcus aureus.Gram-negative bacteria were mainly for 81 strains(21.77%) of haemophilus influenzae,50 strains(13.44%) of e.coli and 28 strains(7.53%) of Moraxella catarrhalis.The risks of streptococcus pneumoniae, haemophilus influenzae,e.coli,staphylococcus aureus,amd Moraxella catarrhalis infections in infants≤1 year old were significantly higher than children>1 year old,the differences were statistically significant(P<0.05).Conclusion:The main bacterial pathogens of CAP were streptococcus pneumoniae,haemophilus influenzae,e.coli,staphylococcus aureus and Moraxella catarrhalis,the infection opportunity in infants within one year old than children over the age of one.关键词
