Does oral intake of Lactobacillus rhamnosus M21 enhance the survival rate of mice lethally infected with influenza virus?
These results demonstrate that orally administered L. rhamnosus M21 activates humoral as well as cellular immune responses, conferring increased resistance to the host against influenza virus infection.
The sudden rise of peptic ulcer disease during the 19th century and the 10-20-yr time lag between gastric and duodenal ulcer are difficult to explain based on changing infection rates with Helicobacterpylori alone. The similarity between the time trends of duodenal ulcer and ulcerative colitis suggests the influence of one or more shared risk factors.
