Abstract

Four strains isolated from chicken small intestine and strains JCM 1038 and JCM 1039 (designated as ) were characterized by phenotypic and molecular taxonomic methods. They were Gram-positive, catalase-negative, facultatively anaerobic rods that did not produce gas from glucose. These strains had similar phenotypic characteristics and exhibited intergroup DNA relatedness values of >77 %, indicating that they comprised a single species. The 16S rRNA gene sequence of a representative strain, JCM 1039 (designated as type strain in this study), was determined and aligned with those of other s species. JCM 1039 was placed in the cluster of the genus on the basis of phylogenetic analysis and formed an independent cluster that was distinct from its closest neighbours, , , , and . Results of DNA–DNA hybridization experiments and whole-cell protein profiles clearly indicated that these strains represent a novel species, for which the name sp. nov. is proposed; the type strain of this species is JCM 1039.
