Bovine fasciolosis is a Æ?Ä?rÄ?ÆÅÆ?c disease of cÄ?ƩůÄ? caused by trematodes usually Fasciola ÅÅÅÄ?nÆ?cÄ?Ä?nÄ? Fasciola Å?Ä?Æ?Ä?Æ?cÄ? in the tropics. The members of this genus are commonly known as liver Å?ƵŬÄ?ÆÍ? The life cycle of these trematodes involves snail as an intermediate host (IH). The disease is found in vast water lodged and marshy grazing Ä®Ä?ůÄ? cŽnÄ?ÅÆ?Žn Ä?nÆ?cÅÆ?Ä?Æ?Ä?Ä? to be ideal for the Æ?rŽÆ?Ä?ÅÄ?Æ?Žn and maintenance of high prevalence of fasciolosis. This disease is widely distributed in areas where cÄ?ƩůÄ? are raised and there is a niche for Lymnaeid snail. The disease is usually characterized by a chronic, ÆŽmÄ?Æ?mÄ?Æ acute or sub-acute ÅnÅ?Ä?mmÄ?Æ?Žn of the liver and bile ducts, accompanied by sub-mandibular oedema, anaemia, anorexia, general ÅnÆ?ŽxÅcÄ?Æ?Žn and death. It is an important ůÅmÅÆ?nÅ factor for bovine Æ?rŽÄ?ƵcÆ?ŽnÍ? It causes several economic losses. The losses may be direct or indirect. The Å?ƵŬÄ?Æ cause severe liver damage and result in total cŽnÄ?Ä?mnÄ?Æ?Žn of liver. Diagnosis of bovine fasciolosis is based on clinical sign, grazing history, seasonal occurrence, Ä?xÄ?mÅnÄ?Æ?Žn of faces by laboratory tests and post-mortem Ä?xÄ?mÅnÄ?Æ?ŽnÍ? In cÄ?ƩůÄ?Í? chronic form of the disease is more common and drugs like rafoxanide and nitroxynil other than triclabendazole are more Ä?Ä«Ä?cÆ?vÄ?Í? The disease can be controlled by reducing the Æ?ŽÆ?ƵůÄ?Æ?Žn of the intermediate host or by using Ä?nÆ?Å?Ä?ůmÅnÆ?cÆÍ?
