"In any case, the recent war on Tapeworms has been justified by research linking them to colic, particularly the type caused by intussusception. This condition occurs when a section of the bowel telescopes into an adjacent portion, causing blockage, inflammation, and abdominal pain. Other studies have found that Tapeworms are capable of secreting substances that interfere with the nerve impulses controlling peristalsis, the wavelike intestinal contractions that push food through the digestive system. As research continues, the message to the horse owner is clear: your horse's chances of staying healthy are better if Tapeworms are eliminated"
