Abstract: Even though half of the world’s population is infected with Helicobacter pylori, which causes gastritis, peptic ulcer and gastric cancer, the transmission routes of these bacteria remain unknown despite extensive epidemiological studies. Enterotoxigenic Escherichia coli (ETEC) and Vibrio cholerae are two of the most common causes of acute watery diarrhea in developing countries. The main aim of this thesis was to study transmission pathways of these bacteria, with a focus on H. pylori, through a... more
