Medical Research: What is the background for this study? What are the main findings?

Dr. Schiestl: When we moved from Harvard to UCLA 13 years ago, after 6 years at UCLA our Atm mouse colony lived significantly 4 fold longer and the frequency of DNA deletions was 4.5 fold reduced and the latency of lymphoma 2.5 fold different. Ultimately we identified the reason behind this as a difference in the intestinal bacteria. The Atm deficient mice are hypersensitive to inflammation and the bacteria reduced inflammation. Then I isolated the most prevalent bacterium among the health beneficial bacteria and this bacterium by itself called Lactobacillus johnsonii 456 reduced genotoxicity and all markers of inflammation.

Medical Research: What should clinicians and patients take away from your report?

Dr. Schiestl: Inflammation causes all cancers, neurodegenerative disease, heart disease, inflammable bowel disease, ulcerative colitis, Lupus, celiac disease, arthritis, asthma and ageing. So a reduction of inflammation should reduce the risk of all those diseases. We have a company, Microbio Pharma, Holding Inc www.microbiopharma.com which produces the bacteria and currently sells Kombucha but will sell also Yogurt, Kefir and capsules with the bacteria.

Medical Research: What recommendations do you have for future research as a result of this study?

Dr. Schiestl: Identifying further health beneficial bacteria to put into the health beneficial capsules and health detrimental bacteria to design baceriophages to kill them.

Medical Research: Is there anything else you would like to add?

Dr. Schiestl: We are very excited to improve the health of everyone.
