Infectious diarrhea : • Secretory diarrhea – Stimulation surface receptors of small intestine (entrocytes) by enterotoxins – Disrupt the physiology of epithelial cells – Large volum, little blood in stool – Staphylococcus aureus, Vibrio cholera, Escherichia coli (ETEC) – Watery diarrhea, risk of dehydration
• Invasive infection – Destruction of enterocytes with bacteria and/orles toxins / virus or parasites – Shigella, Salmonella, E. coli, Yersinia, Campylobacter – Blood in the stool, pain in rectum, fever, ulceration of inner lining
