Actinobaculum Lawson et al. 1997
General information
Description and emendation
On blood agar cells are straight to slightly curved rods, some of which exhibit branching. Hemolysis is not observed. Cells are gram positive, not acid fast, and nonmotile and do not form spores. Anaerobic or facultatively anaerobic and catalase negative. Acid may or may not be produced from glucose. Acid is produced from maltose but is not produced from lactose, mannitol, melezitose, melibiose, raffinose, or sorbitol. The major end product of glucose and/or maltose metabolism is acetate. Esculin and gelatin are not hydrolyzed. Nitrate is not reduced to nitrite. Acetoin is not produced. The cell wall murein type is type A5α (L-Lys-L-Ala-Lys-D-Glu or L-Lys-Lys-D-Glu) The major long-chain CFA are straight-chain saturated and mono-unsaturated fatty acids. The DNA base composition ranges from 55 to 57 mol% G+C.
1: The peptidoglycan is of type A5α, variation L-Lys-L-Ala-Lys-D-Glu. The muramic acid residue of the peptidoglycan is N-acetylated. The diagnostic whole-cell sugars are glucose and rhamnose. The predominant fatty acids are C18:1 ω9c followed by C16:0. Respiratory quinones are absent. The major phospholipids comprise diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and a choline-containing phosphoglycolipid (AbGL). The main end products of maltose fermentation are acetate, ethanol and formate. The G+C content of the DNA is 55 mol%. Members of the genus have been isolated predominantly from veterinary clinical sources, particularly from swine.
