Scientific classification
Kingdom: Bacteria
Phylum: Firmicutes
Class: Bacilli
Order: Lactobacillales
Family: Streptococcaceae
Genus: Enterococcus
Species: E. gallinarum

Enterococcus gallinarum is a species of Enterococcus.[1] E. gallinarum demonstrates an inherent, low-level resistance to vancomycin. Resistance is due to a chromosomal gene, vanC, which encodes for a terminal D-alanine-D-serine instead of the usual D-alanine-D-alanine in cell wall peptidoglycan precursor proteins.[2] That is a separate mechanism than the vancomycin resistance seen in VRE isolates of e. faecium and e. faecalis which is mediated by vanA or vanB.[3] This species is known to cause clusters of infection, although it considered very rare.[4] It is the only other known enterococcal species besides e. faecium and e. faecalis known to cause outbreaks and spread in hospitals.[5]
