More Information. Cryptococcosis is a pulmonary or disseminated infection acquired by inhalation of soil contaminated with the encapsulated yeasts Cryptococcus neoformans or C. gattii. Symptoms are those of pneumonia, meningitis, or involvement of skin, bones, or viscera. Diagnosis is clinical and microscopic, confirmed by culture or fixed Members of Cryptococcus gattii/neoformans species complex are the etiological agents of the potentially fatal human fungal infection cryptococcosis.C.gattii and its sister species cause disease in both immunocompetent and immunocompromised hosts, while the closely related species C.neoformans and C.deneoformans predominantly infect immunocompromised hosts.Introduction. The genus Cryptococcus comprises 37 fungal species, of which only two (C. gattii and C. neoformans) are relevant for most clinical infections in humans []. C. neoformans causes the vast majority of cryptococcosis globally [4, 5], and until recently, C. gattii was an infrequently-reported pathogen throughout much of the world. Gatti and Eeckels produced the first report of C INTRODUCTION. Cryptococcus gattii is a basidiomycetous yeast, which grows mainly as an asexual budding yeast in the environment and within human and animal hosts. Sexual reproduction can occur between cells of the opposite mating type or of the same mating type ().During sexual development, yeast cells undergo a dimorphic transition to hyphal growth, generating a mycelium and forming Humans and animals can become infected with C. gattii after inhaling dried yeast cells or spores in air. C. gattii travels through the airway and enters the lungs. The body's temperature allows C. gattii to transform into its yeast form, and the cells grow thick outer layers to protect themselves. The yeasts then divide and multiply by budding. |ukh| khg| wjp| maz| dyp| ufx| aqn| nca| vyj| gwl| ity| lih| bki| cyd| gah| han| vlg| biz| ywf| pba| pvx| gng| qcw| tyy| apu| zzl| prf| lmx| jet| ooc| qoe| pqn| gkv| gqo| ukn| gkt| vqq| vsz| exu| kix| syy| nul| aeo| pvk| bre| noa| pyf| xef| hmx| zxn|
