Tapeworm (Moniezia expansa) in sheep: anthelmintic treatment studies to assess possible pathogenic effects and production loss in young infected animals in the field

Abstract

Niclosamide and cupric acetoarsenite were both effective in removing tapeworm (Moniezia expansa) from unweaned lambs. In four trials there was no significant liveweight gain in niclosamide-drenched, compared with undrenched, animals. Post-mortem examination for tapeworm showed that although one lamb contained 200 ml (bulk volume) of strobila, 50% of 49 infected animals contained 50 ml or less. The greatest number of scoleces in one animal was 41, and 65% of lambs contained four or fewer. M.expansa is not indicated as a cause of diarrhoea in lambs.

Impact of broad-spectrum anthelmintic treatment in the summer on the weight gain of reindeer calves

“…The Moniezia spp. of Iambs are usually considered rather harmless (Elliott, 1984) but many Russian scientists have associated them with distur-bances in intestinal flora and enterotoxaemia (e.g. Radionov et al, 1985).…”

Sheep enteric cestodes and their influence on clinical indicators used in targeted selective treatments against gastrointestinal nematodes

“…Cestodes from the genus Moniezia are regarded as more pathogenic in young lambs, whereas other cestode genera also recorded in adult sheep are either considered less pathogenic ( Avitellina ) or virtually non-pathogenic ( Stilesia ) (Soulsby 1982). Studies by Elliott (1984) did not consider Moniezia as a cause of diarrhoea in sheep. Conversely, Cabaret et al (2006) found a relationship between diarrhoea in lambs and the presence of Moniezia .…”
