美国加拿大出现一种罕见致命真菌菌株

      据外媒报道，在过去十年里，加拿大与美国出现了一种罕见的真菌，导致了数百人患病、几十人死亡。现在科学家称，在美国看到了这种致命真菌的不同菌株。

    据报道，截至今年6月，加蒂隐球菌（Cryptococcus gatti）已引起171例感染，该菌过去只出现在热带地区，现在已开始在美国肆虐，自2004年爆发以来，俄勒冈州和华盛顿州据报已至少出现100例。

    A rare fungus found in soil and trees has sickened hundreds of people in British Columbia and the Pacific Northwest in the last decade -- and killed dozens -- but scientists now say they're seeing different strains of the potentially deadly bug in additional U.S. states.

    As of June, 171 cases of infection caused by Cryptococcus gatti, a fungus once confined to tropical climates, had been reported in the U.S. That includes at least 100 cases in Oregon and Washington, where officials have been tracking an outbreak since 2004.
