Natural fruits, flowers, honey, and honeybees harbor Helicobacter pylori-positive yeasts.

Different genera of osmotolerant yeasts from flowers, fruits, honey, and honeybees contained H. pylori in their vacuole. High frequency of H. pylori-positive yeasts in these samples might be related to their high sugar content. Insects such as honeybees that facilitate transfer and easy access of these yeasts to nectars serve as the main reservoirs of these yeasts, playing an important role in their protection and dispersal. Accordingly, H. pylori inside these yeasts can be carried by honeybees to different sugar- and nutrient-rich environments. Sugar-rich environments and honeybees play an important role in distribution of H. pylori-positive yeasts in nature.
