4. 2. Studies on bacterial transmission pathways in a high endemic area, with a focus on Helicobacter pylori

   Author : Anders Janzon; Göteborgs universitet; []
   Keywords : H. pylori; enterotoxigenic E. coli; V. cholerae; real-time PCR; transmission pathways; gastroenteritis; mouse infection models; bacterial gene expression;

   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. READ MORE

7. 5. Pathogenetic mechanisms in irritable bowel syndrome

   Author : Hans Törnblom; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Irritable bowel syndrome; functional gastrointestinal disorder; immunohistochemistry; full-thickness biopsy; enteric nervous system; autoantibody; gastroenteritis; risk factor;

   Abstract : Aims of the thesis: To study new pathogenetic mechanisms in IBS; to find out if IBS is a neuromuscular disease affecting the small bowel; to study humoral factors in gut dysmotility associated with visceral neuropathy; and to study the natural history of post-infectious gastro-intestinal (GI) symptoms and risk factors for their development. Material and methods: In studies I and II, full-thickness jejunum biopsies from patients with severe IBS were investigated with immunohistochemistry. READ MORE
