Abstract

A catalase-positive, rod-shaped, non-proteolytic, non-motile, anaerobic bacterial strain, designated B086562T, was isolated from a blood culture of an 84-year-old male patient in Israel. According to 16S rRNA gene sequence phylogeny, this strain has no known close relatives among recognized bacteria but should be placed within the family Lachnospiraceae. The most closely related recognized bacteria were from the 'Clostridium clostridioforme group': C. clostridioforme (92.4 %) and Clostridium bolteae(92.3 %). The isolate produced butyrate, lactate, acetate and succinate as major metabolic end products. The major fatty acids were C16: 0 and C18: 1cis 9 DMA and the DNA G+C content was 46.0 mol%. On the basis of the phenotypic properties and phylogenetic distinctiveness, the blood isolate represents a novel species of a new genus in the family Lachnospiraceae, for which the name Eisenbergiella tayi gen. nov., sp. nov. is proposed. The type strain of Eisenbergiella tayi is B086562T (= LMG 27400T = DSM 26961T = ATCC BAA-2558T).
