Alcaligenes xylosoxidans
Classification
Class: Betaproteobacteria
Order: Burkholderiales
Family: Alcaligenaceae
Genus: Achromobacter (formerly Alcaligenes)
Species: A. xylosoxidans
Background
After it was discovered the only difference between the Alcaligenes and Achromobacter motile strains was the reaction in litmus milk, the genus name Alcaligenes was changed to Achromobacter. [1] Achromobacter signifies colorless rodlet and xylosoxidans implies oxidizing xylose. Although Achromobacter strains had been previously described, Yabuuchi and Ohyama were the first to isolate A. xylosoxidans from ear discharge.[2]
Morphology and Cell Structure
Colonies are circular, flat to convex, smooth, and have an entire margin. The colonies tend to be colorless or grayish white. Cells are rod-shaped and Gram-negative. Cells are motile with a peritrichous flagella arrangement. [3]
