''Cryptococcus gattii'', formerly known as ''Cryptococcus neoformans'' var ''gattii'', is an encapsulated yeast found primarily in tropical and subtropical climates. Its teleomorph is ''Filobasidiella bacillispora'', a filamentous fungus belonging to the class Tremellomycetes. ''Cryptococcus gattii'' causes the human diseases of pulmonary cryptococcosis (lung infection), basal meningitis, and cerebral cryptococcomas. Occasionally, the fungus is associated with skin, soft tissue, lymph node, bone, and joint infections. In recent years, it has appeared in British Columbia, Canada and the Pacific Northwest. It has been suggested〔 that global warming may have been a factor in its emergence in British Columbia. From 1999 through to early 2008, two hundred and sixteen people in British Columbia have been infected with ''C. gattii'', and eight died from complications related to it. The fungus also infects animals, such as dogs, koalas and dolphins. In 2007, the fungus appeared for the first time in the United States, in Whatcom County, Washington〔(Rare, deadly tropical fungus moves into Whatcom County | KOMO-TV - Seattle, Washington | Local & Regional )〕 and in April 2010 had spread to Oregon.〔Potentially deadly fungus spreading in U.S. and Canada http://www.reuters.com/article/idUSTRE63L66H20100422〕 The most recently identified strain, designated VGIIc, is particularly virulent, having proved fatal in 19 out of 218 known cases.〔New, Deadly Cryptococcus Gattii Fungus Found in U.S. http://news.nationalgeographic.com/news/2010/04/100421-new-fungus-cryptococcus-gattii-deadly-health-science/〕 ==Nomenclature== ''Cryptococcus gattii'' previously has had several different names including: *''Cryptococcus neoformans var gattii'' *''Cryptococcus bacillisporus'' 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cryptococcus gattii」の詳細全文を読む スポンサード リンク
