Parasitic cysts
Image of Taenia hydatigena cyst in ovine omentum from Cornell Veterinary Medicine
- Taenia hydatigena (Cysticercus tenuicollis) in ruminants - liver, mesentery, peritoneum - large fluid filled.
- Taenia pisiformis (Cysricercus pisiformis) in lagomorphs
- Taenia ovis (Cysticercus ovis) - sheep, diaphragm - small, firmer.
- Mesocestoides in carnivores causing pyogranulomatous peritonitis or parasitic ascites
Hydatid cysts
- Echinococcus granulosus - any mammal including man
Other parasites
- Fasciola hepatica larvae cause chronic or acute peritonitis in cattle and sheep
- Stephanuris dentatus in pigs causes local haemorrhage, peritonitis and perihepatitis through its migration through liver and peritoneal cavity
- Strongylus edentatus and Strongylus equinus migrate through liver and peritoneal cavity, sometimes cause eosinophilic granulomas in mesenteries and omentum of horses
- Ascarids may cause obstruction or rupture of small intestines or bile duct
- Setaria spp. use peritoneal cavity of many herbivores as their final destination
- Dead individuals may cause granulomatous peritonitis
- Sheathed microphilariae deposited in the peritoneal cavity move to blood and are transferred to their intermediate hosts, the mosquitos or other biting insects
