Could beta-hemolytic, group B Enterococcus faecalis be mistaken for Streptococcus agalactiae?

摘要

A beta-hemolytic Enterococcus faecalis strain agglutinating Lancefield group A, B, C, D, F, and G antisera was observed from a rectovaginal swab, in the context of antenatal screening for Streptococcus agalactiae (group B Streptococcus [GBS]). This is the first multi-Lancefield antisera-agglutinating isolate of this species, and it raised particular concern, as it may mimic GBS, leading to false reporting and useless receipt of intrapartum antibiotics.
