Analysis of carrying status and drug susceptibility of Streptococcus agalactiae in genital tract of pregnant women / 国际检验医学杂志

ABSTRACT

Objective To understand the carrying status and drug resistance of streptococcus agalactiae in the genital tract of pregnant women.Methods The vaginal discharge from pregnant women was collected for conducting the bacterial culture.The iso-lated streptococcus agalactiae was performed the identification and the drugs susceptibility test by the VITEK 2 fully automatice bacterial identification analyzer.Results Among 1 042 samples,streptococcus agalactiae was isolated in 6 cases with the separation rate of 5.4%.The drug sensitivity test showed the Streptococcus agalactiae was highly sensitive to penicillin,cefazolin,vancomycin, linezolid and nitrofurantoin.The intermediate strains or drug resistant strains were not found.The sensitive rate to levofloxacin, moxifloxacin and clindamycin,erythromycin,tetracycline were 84.0%,84.0%,71.4%,39.3% and 8.9% respectively.Conclusion The carrying rate of streptococcus agalactiae in pregnant women is not high in our hospital.Penicillin and cefazolin should be as the drug of first choice for therapy and the clincal and laboratory nould payattention to detection of streptococcus agalactiae in pregnant women.
