| Moniezia and Anoplocephala Distribution Course in body Definitive Host Life Cycle Clinical Signs Diagnosis Treatment Zoonotic? | Worldwide GI tract Moniezia (Ruminants) and Horses (Anoplocephala) Indirect Cycle: Eggs in manure, oribatid mite ingests egg, hatch and mature to cysticercoids, horse ingests mite, travel to ileocecal junction, mature and reproduce Clinical signs: Diarrhea and colic Diagnosis: ID segments, eggs in feces, antigen test Treatment: albendazole (ruminants) or praziquantel/pyrantel (horses), control mites, stocking density, pasture rotation, feces removal Not zoonotic |
