In 1894 with pathologist Otto Busse (1867–1922), Buschke described an infectious disease caused by the fungus Cryptococcus neoformans.
The yeast Cryptococcus neoformans, though not a bacterium, has a similar capsule.
She would expose the organisms against two fungi, Candida albicans and Cryptococcus neoformans.
A protein from Cryptococcus neoformans (Filobasidiella neoformans) that contains haemerythrin/HHE cation-binding domains is also involved in nitric oxide response.
Cryptococcus neoformans is a basidiomycetous fungus that grows as a budding yeast in culture and in an infected host.
In 1894 Busse was the first to provide a written account of cryptococcosis, caused by a yeast-like fungus now known as Cryptococcus neoformans.
Organisms that are most frequently associated with brain abscess in patients with AIDS are poliovirus, Toxoplasma gondii, and Cryptococcus neoformans, though in infection with the latter organism, symptoms of meningitis generally predominate.
