Description
Summary:Summary The plant flora has an important role in the ecology of Cryptococcus neoformans. It is estimated that the environmental spreading and contamination of human beings with this yeast occurs via contaminated particles of plants. Cultivation of canopy parts of plants in selective media is the most widely used isolation method of this yeast. Cryptococcus neoformans var. grubii was isolated from honeybee colonies in Eucalyptus forests but was not isolated from the places where this flora did not exist. Our results indicate that the occurrence of C. neoformans in honeybee colonies during the flowering season of Eucalyptus spp. trees can be an important bioindicator for environmental yeast presence. The screening of honeybee colonies is a practical and a rapid method for the monitoring of the C. neoformans presence in flowering plants. Zusammenfassung Es wird angenommen, dass die Exposition des Menschen für Cryptococcus neoformans von Pflanzen ausgeht. Cryptococcus neoformans var. grubii konnte aus Stöcken der Honigbiene (Apis mellifera) in Eucalyptus Beständen isoliert werden, jedoch nicht aus Stöcken anderer Standorte. Der Nachweis von C. neoformans in Bienenstöcken während der Blühperiode von Eucalyptus‐Arten könnte daher als praktischer und schnneller Bioindikator für die Ökologie dieser Hefe dienen.
