Hydatid disease is caused by the tapeworm of genus ;Echinococcus. Genus Echinococcus has different species including Echinococcus vogeli, Echinococcus granulosus and Echinococcus multilucularis. Echinococcus granulosus is the most common cause of hydatid disease in humans. This disease can take place either directly through ingestion of parasite eggs from contact with infected dogs or indirectl...

We report an uncommon case of a primary Echinococcus cyst that developed in the subcutaneous tissue of the right popliteal fossa, at the spot of a previous wasp sting, suggesting the possibility of an unusual transmission of the eggs by insects. This unusual presentation was initially considered as a Baker cyst until parasytological results verified Echinococcus hydatidosus, the larval form of ...

Human echinococcosis is a zoonotic infection caused by larval forms (metacestodes) of tapeworms of the genus Echinococcus. Among the recognised species, Echinococcus granulosus and E. multilocularis are of considerable medical importance, causing cystic and alveolar echinococcosis (AE and CE), respectively. The factors of immunology, host-genetic inherits, and Echinococcus genetic-diversity and...

Many issues concerning the taxonomy of Echinococcus have been resolved in recent years with the application of molecular tools. However, the status of Echinococcus maintained in transmission cycles involving cervid intermediate hosts remains to be determined. The recent characterization of the parasite from cervids in Finland has highlighted the paucity of data available, particularly that from...

This review provides an update of the biological aspects of the genus Echinococcus and focuses on newly recognized endemic areas. Infection with the intermediate cystic stage of all species of Echinococcus causes disease and incapacity in animals and humans, and in the most serious cases, death of the host. Transmission of Echinococcus to new continents has occurred during European colonisation...

In view of the medical, veterinary and economic importance of hydatid disease in India, our study aimed to determine the prevalence and genotypes of Echinococcus present in domestic livestock in India. Out of 21,861 animals examined, cattle were found with the highest prevalence of hydatid cysts (5.10%) followed by buffaloes (3.81%), pigs (0.87%) and sheep (0.075%). Phylogenetic analysis of the...

Our study showed that open pastures had more small mammal burrows than fenced pastures in Tibetan pastoralist communities in 2003. This characteristic was linked to a higher prevalence of Echinococcus multilocularis in dogs and indicates that pasture type may affect E. multilocularis transmission.
