Inhibition of Helicobacter pylori and associated urease by oregano and cranberry phytochemical synergies

Article Abstract:

The potential for using phenolic phytochemical extracts to inhibit Helicobacter pylori in a laboratory medium is determined by developing a specific phenolic profile with optimization of different ratios of extract mixtures from oregano and cranberry. The results have shown that the synergistic contribution of oregano and cranberry phenolics might be more important for inhibition than any species-specific phenolic concentration and the likely mode of action might be through urease inhibition and disruption of energy production by inhibition of proline dehydrogenase at the plasma membrane.

Inhibition of Listeria monocytogenes in fish and meat systems by use of oregano and cranberry phytochemical synergies

Article Abstract:

The optimized phenolics from oregano and cranberry extracts are evaluated for antimicrobial activity against Listeria monocytogenes in laboratory media and in beef and fish. It was found that the inhibition by photochemical and lactic acid synergies was most effective when beef and fish slices were stored at 4 degree Centigrade.

Coccoid form of helicobacter pylori as a morphological manifestation of cell adaptation to the environment

Article Abstract:

Study conducted by characterizing the preferred conditions for Helicobacter pylori survival in the sessile state found that the bacterium transforms from spiral to coccoid under mild circumstances. This supports the view that transformation into the coccoid form is an active, biologically led process.
