how does liver fibrosis come about in schistosomiasis? |
|
Definition
granulomas migrate toward the lumen of the gut wall or bladder (depending on which species and which route the ova are passed) --> cells of the granuloma are released into the lumen and granulomas disintegrate --> egg with hard shell comes out and half of all the eggs released exit via urine or feces --> other 1/2 get swept to liver and anchored in smaller blood vessels --> wherever they get stuck cause granulomatous rxn --> granulomata undergoes fibrosis |
