Tape worms (Anoplocephala)
Tapeworms are generally not thought to cause much problem to horses. However, in the last few years there seems to have been an increase in the number of horses being infected with tapeworms. The normal deworming medications are generally not very effective at eliminating these worms.

Therefore, in areas where these worms are known to be present special deworming methods and medications must be used to control this worm. Fortunately this worm does not cause horses a great amount of difficulty. However, in certain situations this worm may cause colic therefore efforts should be made to control them.
