Name honors R.L. Moniez (1852–1936).
English: Sheep Tapeworm.
Genus of Eucestoda, family Anoplocephalidae.
Moniezia expansa worms occur worldwide in the small intestine of ruminants, reach a length of 10 m, and their posterior proglottids are very broad (∼2.5 cm) (Figs. 1, 2, page 842). These proglottids are characterized by the presence by a double set of sexual organs being situated at the 2 lateral sides of the proglottids. Intermediate hosts are oribatid mites, which are fed together with grass. The prepatent period takes about 30–52 days, patency lasts 3–8 months. Anaemia, diarrhoea, loss of weight are the most common signs of disease. Diagnosis is done by finding the characteristic proglottids around the anus or by the determination of eggs in the faeces.
