Enterococcus hirae, a New Species That Includes Amino Acid Assay Strain NCDO 1258 and Strains Causing Growth Depression in Young Chickens

Abstract

Deoxyribonucleic acid base composition, deoxyribonucleic acid-deoxyribonucleic acid hybridization, lipid, and biochemical studies were performed with Enterococcus faecium NCDO 1258 (S= Snell strain R) and other atypical Enterococcus faecium strains from pigs and chickens in an attempt to clarify their taxonomy. Our results indicate that these strains constitute a new species, for which the name Enterococcus hirae sp. nov. is proposed. The type strain of Enterococcus hirae is strain NCDO 1258.
