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 : 1 cis 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).
