Does Quinolone- or Macrolide-Resistant Streptococcus agalactiae Bacteremia Affect Patient Outcome? A Multicenter Cohort Study

Jpn J Infect Dis. 2021 May 24;74(3):240-244. doi: 10.7883/yoken.JJID.2020.589. Epub 2020 Oct 30.

Abstract

The prevalence of quinolone- and macrolide-resistant Group B Streptococcus (GBS) is increasing worldwide, but the relationship between the resistance of GBS to these antibiotics and patient outcome remains unclear. Therefore, we evaluated whether blood stream infection caused by quinolone- or macrolide-resistant GBS is associated with high mortality. Our findings in 77 patients with GBS bacteremia demonstrate that quinolone and macrolide resistance may not be risk factors for 30-day mortality.

Keywords: Streptococcus agalactiae; macrolide; quinolone; resistance.
