Abstract:
Objective To study the characteristics of lower respiratory tract infection by Streptococcus pneumonia in children aged from 0 to 5 years and drug resistance,so as to provide the rational basis for clinical treatment and epidemiology.Methods The medical data from 4 815 children aged 0 to 5 years with lower respiratory tract infection between September 2014 and September 2016 were retrospectively reviewed.Results Totally 343 strains of Streptococcus pneumonia were isolated from 4 815 sputum samples,with the isolation rate of 7.12％.Of the isolated streptococcus pneumonia strains,80.76％ were isolated from the children with pneumonia,9.33％ were isolated from the children with bronchitis,5.83％ were isolated from the children with capillary bronchitis,4.08％ were isolated from the children with bronchial asthma.There was no significant difference in the incidence of Streptococcus pneumonia infections between the genders of the children(P>0.05),but the incidence of Streptococcus pneumonia detection rates differed significantly in different seasons and children of different ages,the difference was statistically significant(P<0.05).The resistance rates of Streptococcus pneumonia to penicillin,erythromycin and clindamycin were 51.0％,97.9％ and 97.1％ respectively;The sensitivity rates to cefotaxime and vancomycin were 71.1％ and 100.0％ respectively.Conclusion The children aged less than 1 years old are at the high risk of Streptococcus pneumonia infection and highest detection rates in winter,it is necessary to perform the drug susceptibility testing in a timely manner so as to choice reasonable antimicrobial agents to control the condition.
