Moryella indoligenes gen nov, sp nov, an anaerobic bacterium isolated from clinical specimens

Three Gram-positive, anaerobic, non-spore-forming, rod-shaped bacteria with pointed ends were isolated from clinical specimens. The organisms were weakly saccharolytic and produced indole, acetate, butyrate and lactate as major metabolic end products. 16S rRNA gene sequence analysis indicated that the isolates had no known close relatives among recognized bacteria but that they exhibited a phylogenetic association with Clostridium rRNA cluster XlVa [as defined by Collins, M. D. et al. (11994). Int J Syst Bacteriol 44, 812-826]. The closest recognized relatives were the type strains of Clostridium clostridioforme, Clostridium bolteae and Clostridium asparagiforme (16S rRNA gene sequence similarity values of 90.2-91.4%). These results suggest that these three clinical isolates represent a novel species of a new genus, for which the name Moryella indoligenes gen. nov., so. nov. is proposed. The type strain of Moryella indoligenes is AIP 220.04(T) (= CIP 109174(T) = CCUG 52648(T)).
