Aggregative Adherence Fimbriae I (AAF I) causes aggregation of the bacterial cells. These aggregate on small intestinal cells and cause mucous secretion which produces a biofilm. Enteroaggregative heat stabile toxin is an STa like toxin, and plasmid encoded toxin can also be present.
1 Umbilical hernia is a bulge around the belly button. It occurs when the muscle around the belly button does not close completely after birth.  Inguinal hernia is a bulge in the groin. It is more common in men.
What Happens. Inguinal hernias typically flatten or disappear when they are pushed gently back into place or when you lie down. Over time, hernias tend to increase in size as the abdominal muscle wall becomes weaker and more tissue bulges through. If you can't push your hernia back into your belly, it is incarcerated. A hernia gets incarcerated when tissue moves into the sac of the hernia and fills it up. This is not necessarily an emergency. But if a loop of the intestine is trapped very tightly in the hernia, the blood supply to that part of the intestine can be cut off (strangulated), causing tissue to die.
