A review of the global prevalence, molecular epidemiology and economics of cystic echinococcosis in production animals.

Cystic echinococcosis (CE) is an important and widespread zoonotic infection caused by the larval stages of taeniid cestodes of the genus Echinococcus. The disease represents a serious animal health concern in many rural areas of the world, causing important economic losses derived from decreased productivity and viscera condemnation in livestock species. In this review we aim to provide a comprehensive overview on recent research progress in the epidemiology of CE in production animals from a global perspective. Particular attention has been paid to the discussion of the extent and significance of recent molecular epidemiologic data. The financial burden associated to CE on the livestock industry has also been addressed. Data presented are expected to improve our current understanding of the parasite's geographical distribution, transmission, host range, immunogenicity, pathogenesis, and genotype frequencies. This information should be also valuable for the design and implementation of more efficient control strategies against CE.
