Fasciolosis -- Public Health and Economic Impacts: A Review
Journal Title: International Journal of Zoological Investigations - Year 2018, Vol 4, Issue 2
Abstract
Fasciolosis is a disease caused by trematodes of the genus Fasciola. The parasite has worldwide distribution, and is commonly referred to as “liver flukes”. The two most known species of Fasciola; namely, Fasciola hepatica and F. gigantica are the causative agents of fasciolosis. The lifecycle of Fasciola entirely depends on snails of the genus Lymnaea. The disease predominantly affects cattle, sheep and goats, and occasionally humans. In animals, the disease is characterized by gradual loss of condition, progressive weakness, anaemia and hypoproteinaemia with development of edematous sub-cutaneous swelling especially in the inter-mandibular space and over the abdomen. Fasciolosis poses significant economic losses due to carcass condemnations, loss of productivity and cost of drugs as a therapy each year worldwide. Fasciolosis is thought to infect about 17 million humans worldwide and a further 180 million at risk of infection. The disease is cured by administration of appropriate chemotherapeutics, especially, Triclabendazole (Fasinex), which is effective against all stages of Fasciola. Prevention and control of fasciolosis should be targeted on drainage of stagnant water bodies and snail control strategies.
