Enterococcaceae was one of two dominant pathobiont families that significantly expanded in the gut microbiota of critically ill ICU patients compared to healthy controls (p=0.0334), representing a key feature of ICU-associated dysbiosis in a prospective cohort of 51 patients.

E2 — Moderate human evidence
E1 — Limited / preliminary
Enterococcaceae gut bloom in an ICU patient was associated with a nosocomial urinary tract infection caused by Enterococcus faecalis that progressed to secondary bloodstream infection, representing a direct clinical consequence of gut Enterococcaceae expansion documented in a single case within a 51-patient prospective cohort.
