Introduction

Cryptococcus gattii is a fungal pathogen originating in Australian eucalyptus and almond trees [2]. that has been known to cause respiratory failure and serious central nervous system complications when infecting a human host [3]. Although the pathogenicity of C. gattii has in large part already been investigated, the global distribution of the microbe is unclear because strains of the fungus have only been found in places where samples are tested - areas of high-incidence [4]. This yeast is endemic in parts of Australia, and is normally found in tropical and subtropical areas. However, it has recently been identified as the cause of a cryptococcosis outbreak in British Columbia and parts of the American Pacific Northwest [2]. C. gattii is a leading cause of pulmonary cryptococcosis, basal meningitis, and cerebral cryptococcomas whose emergence, it has been suggested, is a result of changing climate conditions [5].

Other

2000-2001 Outbreak: Between January 1999 and December 2001, an outbreak of cryptococcosis occurred in British Columbia [12]. Approximately 38 cases of human cryptococcosis were recorded; all were caused by C. gattii. 95.2% of these human cases were identified as the VGII strain, and the remaining case was identified as VGI [12]. All isolates from environmental samples were identified as the VGII strain, which was determined to have caused this outbreak in British Columbia. British Columbia and the Pacific Northwest are both new locations for this microbe; C. gattii was previously found only in tropical and subtropical locations [12].
