AB Cryptococcosis associated with AIDS is mainly due to Cryptococcus
neoformans var. neoformans which is found in saprophytic form in pigeon
droppings. This variety has been isolated in Central Africa,
particularly in Zaire, Burundi and Rwanda, from dust collected from the
houses of patients with cryptococcosis. Several patients confirmed
frequent contact with pigeons. Recent studies in Australia demonstrated
a link between the yeast and Eucalyptus of the camaldulensis and
teriticornis species. These two species were imported to Central Africa
from Australia. Examination of 657 Eucalyptus specimens collected in
Rwanda did not detect the yeast in any type of tree. This finding casts
doubt on the role of Eucalyptus in the ecology of cryptococcosis in
Central Africa.
