Helicobacter pylori release from yeast as a vesicle-encased or free bacterium.

Escape of intracellular H. pylori from yeast as a membrane-bound or free bacterium indicates that H. pylori uses safe exit mechanisms that do not damage the host which is the principle of symbiotic associations. In human stomach, certain conditions may stimulate yeast cells to release H. pylori as a vesicle-encased or free bacterium.
