The genus Pyramidobacter comprises strains that are anaerobic, non-motile, asaccharolytic
bacilli that produce acetic and isovaleric acids and small quantities of propionic and isobutyric acids .
During the following decade, additional clinical isolates with the same microbiological characteristics (slow-growing, gram-negative, small coccoid, asaccharolytic
, oxidase negative, nonmotile and brown-soluble-pigment-producing) were submitted to the CDC for identification (10).
Characteristics and Sites of Infection of Eubacterium nodatum, Eubacterium timidum, Eubacterium brachy, and Other Asaccharolytic
Nitrogen and amino acid from protein provides energy sources for the growth of saccharolytic and asaccharolytic
bacteria (Scott et al., 2013).
Because it is an asaccharolytic
species, erroneous identification may occur.
The organism's phenotypic characteristics were similar to asaccharolytic
strains of Acinetobacter, but differed in their cellular morphology and cellular fatty acid profile.
Bordetella holmesii is a recently described gram-negative, asaccharolytic
, nonoxidizing, soluble, brown-pigment-producing rod previously known as CDC nonoxidizer group 2 (NO-2) (1).
