''Trichuris'', often referred to as whipworms (which typically refers to ''T. trichiura'' only in medicine, and to any other species in veterinary medicine), is a genus of parasite worms from the roundworm family Trichuridae, which is a type of helminth. The name whipworm refers to the shape of the worm; they look like whips with wider "handles" at the posterior end. The name ''Trichocephalus'' is sometimes used for this genus. The genus ''Trichuris'' includes over 20 species which infect the large intestine of their host including: * ''Trichuris trichiura'' (sometimes ''Trichocephalus trichiuris'') - causes trichuriasis in humans] * ''Trichuris campanula'' (cat whipworm) * ''Trichuris suis'' (pig whipworm) * ''Trichuris muris'' (mouse whipworm) * ''Trichuris vulpis'' (dog whipworm) A new species - as yet unnamed - has been identified in François’ leaf monkey(''Trachypithecus francoisi'').〔Liu GH, Gasser RB, Nejsum P, Wang Y, Chen Q, Song HQ, Zhu XQ (2013) Mitochondrial and nuclear ribosomal DNA evidence supports the existence of a new ''Trichuris'' species in the endangered François' leaf-monkey. ''PLoS One'' 8(6):e66249. 〕 Other species in this genus include ''Trichuris cynocephalus'', ''Trichuris discolor'', ''Trichuris laevitestis'',''Trichuris pardinasi'', ''Trichuris navonae'',''Trichuris ovis'', ''Trichuris rhinopithecus'', ''Trichuris thrichomysi'' and ''Trichuris travassosi''. Trichurias is a soil-transmitted helminthias and belongs to the group of neglected tropical diseases, affecting about 604 million people globally. ==Other animals== Whipworms develop when a dog swallows whipworm eggs, passed from an infected dog. Symptoms may include diarrhea, anemia, and dehydration. The dog whipworm (''Trichuris vulpis'') is commonly found in the U.S. It is hard to detect at times, because the numbers of eggs shed are low, and they are shed in waves. Centrifugation is the preferred method. There are several preventives available by prescription from a veterinarian to prevent dogs from getting whipworm. The cat whipworm is a rare parasite. In Europe it is mostly represented by ''Trichuris campanul''a, and in North America it is more often ''Trichuris serrata'' more often. () () Whipworm eggs found in cats in North America must be differentiated from lungworms, and from mouse whipworm eggs that are just passing through. ''Trichuris campanula'' can be found in cats throughout the United States, having a whip like shape, living in the large intestine and cecum of cats. ''T. campanula'' is closely related to ''T. vulpis'' which is a dog whipworm. They both come belong the ''Trichuris'' genus that are roundworms also known as whipworms. The cat gets infected with ''T. campanula'' by ingesting food or water that is contaminated with the whipworm eggs. Once the cat ingests the infected eggs, they hatch and the larvae mature as adults in the large intestine where they feed on the blood from the intestinal wall. The ''T. campanula'' lays eggs that are passed in the feces of the infected cat, remaining alive in soil for years. The infection can be found by examining the feces of the infected cat. Also, blood can be found in the feces that can help in diagnosing of the infected cat. For prevention, cats should visit the veterinarian to get worming, having the feces inspected. Pet owners should be more aware of what their pets consume, and pick up the cat feces to prevent future infections from occurring. Also, litter boxes need to be cleaned to remove any contaminated feces. Currently, there are no drugs to help infected cats remove all of the worms. The best way to avoid a cat being infected is by practicing good prevention techniques. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Trichuris」の詳細全文を読む スポンサード リンク
