![]() ![]() Sheep and goats serve as intermediate hosts for several other species of tapeworms. Moniezia benedeni, more common in cattle, can also be found in sheep and goats. Moniezia expansa is the tapeworm that commonly affects sheep and goats. Once inside the animal, it takes 6 to 7 weeks for the larvae to develop into adult tapeworms. Sheep and goats become infected when they ingest the mites containing tapeworm larvae. To see one well, you would need a microscope. Hundreds of thousands can live in one square meter of soil. Sometimes they can be found in plant material. Oribatid mites live in the top layer of soil. These mites ingest the eggs while feeding and the larval stages of the worm develop inside the mites. All of the important species affecting sheep, goats, and cattle require pasture mites. Different tapeworms require different intermediate hosts. ![]() These segments are packed with eggs.Ĭestodes (tapeworms) require an intermediate host to complete their life cycle. Mature tapeworms shed segments, which are expelled with the feces. The adult tapeworm consists of a head (scolex), where the worms attaches itself to the mucosa of the intestine a neck and a segmented body that contains both male gonads and female gonads (proglottids). The rest of the tapeworm is made up of a chain of flat segments. Cestodes lack an intestinal tract, but are able to absorb nutrients through their skin.Īdult tapeworms have hooks, spiny structures, or suckers on their head, which allow them to attach to the wall of the intestine. The other classes are Nematoda (roundworms) and Trematoda (flukes). They are long, segmented worms of the class Cestoda, which comprise one of three classes of parasitic worms. Tapeworms are flat, ribbon-shaped worms that live inside the intestines of humans or animals that have a spine. ![]()
