Analysis of Pathogens of Lower Respiratory Tract Infection in Children

Objective To investigate the pathogens causing lower respiratory tract infection and drug sensitivity of the pathogens, and direct the use of drugs for treating the infection. Method Sputum cultivation and drug sensitivity tests were performed for 526 children with lower respiratory tract infection. The pathogenic bacteria were identified and determined the drug sensitivity in 132 cases of positive reaction to sputum cultivation. Results The detectable rate of pathogenic bacteria was 25.1%, in which 85 strains of gram-negative bacteria (64.4%) and 47 strains of gram-positive bacteria(35.6%) were detected. Escherichiacoli(l8.9%) , Klebsiella pnenmoniae(13.6%), Staphylococcus epidermidis (9.8%), verdigris Pseudomonca (9.1%) and hemolytic Staphylococcus (8.3%) were the main strains. All of the gram-negative bacteria were sensitive to iraipenem. Conclusions Escherichia coli and Klebsiella pneumoniae became the main pathogenic bacteria of children's lower respiratory tract infection.The detected gram-negative bacteria were sensitive to imipenem and cefepime.
