It is a close relative of E. coli and other animal pathogens that include Salmonella , Shigella , Klebsiella , Proteus bacterium Proteus and Yersinia . Members of this family are facultative anaerobe s, able to ferment sugars to lactic acid , have nitrate reductase, but lack oxidase s. Even though many clinical pathogens are part of the Enterobacteriaceae family, most members of this family are plant pathogens. In the natural plant environment, Erwinias cause plant maladies such as necrosis , blight and soft rot, a progressive tissue maceration Disambiguation needed date July 2011 . Erwinia chrysanthemi contains many pectinase s that are able to macerate and break down the plant cell wall material. This exposed part of the plant releases nutrients that can facilitate bacterial growth. Commonly infected plants include potato tuber s, bulbs of vegetables , and ornamental Crop agriculture crops .
