Abstract

A study of the yeast flora of 328 honey stomachs from 7 different pollinating bee species, and 342 flower nectar samples of 9 different flower species yielded 766 yeast isolates composed of 16 genera and 47 species. Most of the yeast species from both the sources belonged to the genusCandida, while the most frequently isolated yeasts wereDekkera intermedia from honey stomach andCandida blankii from flower nectar. Among the honey bees,Xylocopa sp., and among flowers,Citrus medica, yielded the highest number of yeast species. Nineteen species of yeasts belonging to 9 genera were common to both the sources.
