f2: Scanning electron micrograph of E. lenta VPI 0255T (Manfred Rohde, Helmholtz Centre for Infection Biology, Braunschweig)

Mentions: E. lenta strain VPI 0255T was originally isolated from a rectal tumor and described as Gram-positive, non-motile and non-sporulating (Table 1) [1]. Cells are rod shaped and occur singly or in long chains up to 20 elements (Figure 2). The cell size and morphology varies depending on the substrate and the age of the culture. Surface colonies were described as circular to slightly scalloped, convex, shiny, gray and translucent. E. lenta is obligately anaerobic and its optimal growth temperature is 37° C [4]. Growth is stimulated by arginine. The existence of the arginine dihydrolase pathway as an important energy source was described by Sperry and Wilkens in 1976 [26]. E. lenta is asaccharolytic [4,26,29], Gelatin is not liquefied, aesculin is not hydrolyzed and nitrate is reduced [29]. E. lenta is bile-resistant and primarily found in human feces [6].

Bottom Line: Eggerthella lenta (Eggerth 1935) Wade et al. 1999, emended Würdemann et al. 2009 is the type species of the genus Eggerthella, which belongs to the actinobacterial family Coriobacteriaceae.The strain described in this study has been isolated from a rectal tumor in 1935.Here we describe the features of this organism, together with the complete genome sequence, and annotation.

ABSTRACT
Eggerthella lenta (Eggerth 1935) Wade et al. 1999, emended Würdemann et al. 2009 is the type species of the genus Eggerthella, which belongs to the actinobacterial family Coriobacteriaceae. E. lenta is a Gram-positive, non-motile, non-sporulating pathogenic bacterium that can cause severe bacteremia. The strain described in this study has been isolated from a rectal tumor in 1935. Here we describe the features of this organism, together with the complete genome sequence, and annotation. This is the first complete genome sequence of the genus Eggerthella, and the 3,632,260 bp long single replicon genome with its 3123 protein-coding and 58 RNA genes is part of the Genomic Encyclopedia of Bacteria and Archaea project.
