Antibiotic resistance of Streptococcus pneumoniae of children′s sputum

Objective To understand the drug resistance of Streptococcus pneumoniae in the pediatric sputum culture,and provide the reference for clinical rational use of drugs.Methods Court Streptococcus pneumoniae isolated from pediatric sputum culture from 2009 to 2012,were identified using the U.S.BD PhoenixTM100 fully automatic identification of susceptibility analyzers,quality controlled with reference strains.Results From 2009 to 2012,the detection rate of Streptococcus pneumoniae were 7.27%,8.11%,9.20%,and 10.67%,respectively;the overall positive rate was increasing;the most obvious of increased resistance was Large ring lactone class of drugs,was accounting for more than 97%;cephalosporin class sensitivity was although a slight decline,but sensitive rate was still above 92%.Conclusion Childhood respiratory Streptococcus pneumoniae carried rate was relatively high.Infection positive rate showed a trend of increased year by year,and drug resistance also increased gradually.
