Erosions and gastroesophageal ulcers (GEU) were produced in the pars esopha
gea of young gnotobiotic swine fed a carbohydrate-enriched liquid diet and
monoinfected with two different fermentative commensal bacteria, Lactobacil
lus and Bacillus sp. In contrast, piglets, fed a similar diet and inoculate
d with Gastrospirillum sp. (Helicobacter heilmannii), a helicobacter specie
s that colonizes the gastric mucosa, did not develop GEU. Experimental GEU
likely develops secondary to epithelial damage mediated by microbial-origin
acids whose production is potentiated by high dietary carbohydrate and par
ietal cell-origin hydrochloric acid.
