where does the h pylori bacteria come from?
the stomach
in "h pylori pioneers", dr. marshall noted that other physicians had produced evidence of "h. pylori" infection as early as 1892. marshall writes that earlier reports were disregarded because they conflicted with existing belief. the first description of "h. pylori" came in 1892 from giulio bizzozero, who identified acid-tolerant bacteria living in a dog’s stomach. later, a theory would be developed that no bacteria could live in the stomach. although the theory has no scientific basis, it would become a stumbling block for scientists, discouraging them for searching for infective causes of stomach ulcers. in 1940, two physicians, dr. a. stone freeberg and dr. louis e. barron published a paper describing a spiral bacteria found in about half of their gastroenterology patients who had stomach ulcers. dr. john lykoudis, a greek physician, was one of the first physicians to treat stomach ulcers as an infectious disease. between 1960 and 1970, he treated over 10,000 ulcer patients in athens with antibiotics. lykoudis tried to publish a paper on his findings, but they conflicted with traditional theory, and his work was never published. lykoudis' experience was followed in 1975 by a further publication in gut magazine that included spiral bacteria living on the borders of duodonal ulcers. the medical significance of steer’s findings was disregarded, but he “continued to publish papers on "h. pylori", mostly as a hobby."
history of emerging infectious diseases
ingesting lactic acid bacteria exerts a suppressive effect on "h. pylori" infection in both animals and humans, and supplementing with "lactobacillus"- and "bifidobacterium"-containing yogurt improved the rates of eradication of "h. pylori" in humans. symbiotic butyrate-producing bacteria which are normally present in the intestine are sometimes used as probiotics to help suppress "h. pylori" infections as an adjunct to antibiotic therapy. butyrate itself is an antimicrobial which destroys the cell envelope of "h. pylori" by inducing regulatory t cell expression (specifically, foxp3) and synthesis of an antimicrobial peptide called ll-37, which arises through its action as a histone deacetylase inhibitor.
