{{Short description|Disease of some Rosaceae trees (especially apples and pears) caused by Erwinia amylovora}} {{Speciesbox | image = Apple_tree_with_fire_blight.jpg | genus = Erwinia | species = amylovora | authority = (Burrill 1882) Winslow ''et al.'' 1920 | type_strain = ATCC 15580; CFBP 1232; [http://www.ncppb.com/furtherinfo.cfm?ncppb_no=683 NCPPB 683] }} '''Fire blight''', also written '''fireblight''', is a [[contagious disease]] affecting [[apple]]s, [[pear]]s, and some other members of the family [[Rosaceae]]. It is a serious concern to apple and pear producers. Under optimal conditions, it can destroy an entire [[orchard]] in a single growing season. The causal [[pathogen]] is '''''Erwinia amylovora''''',<ref>[http://www.ncppb.com/furtherinfo.cfm?ncppb_no=683 Type strain NCPPB 683] {{Webarchive |url=https://web.archive.org/web/20120222073750/http://www.ncppb.com/furtherinfo.cfm?ncppb_no=683 |date=2012-02-22 }} (dead link 3 December 2019)</ref> a [[Gram-negative]] [[bacterium]] in the genus ''[[Erwinia]]'', order [[Enterobacterales]]. It is a short rod with rounded ends and many peritrichous flagellae. [[Pear]]s are the most susceptible, but [[apple]]s, [[loquat]], [[crabapple]]s, [[quince]]s, [[Crataegus|hawthorn]], [[cotoneaster]], ''[[Pyracantha]]'', [[raspberry]] and some other rosaceous plants are also vulnerable. The disease is believed to be indigenous to [[North America]], from where it spread to most of the rest of the world. Fire blight is not believed to be present in [[Australia]] though it might possibly exist there.<ref>{{cite news |url=http://www.accessmylibrary.com/article-1G1-19464464/australia-new-zealand-trade.html |work=Agra Europe |title=Australia, New Zealand trade insults over fire blight.
