Echinococcus vogeli is a parasitic tapeworm from the genus Echinococcus and one of the two pathogens of polycystic echinococcosis, an emerging infectious disease in South and Central America.
Human transmissions extend from Nicaragua to Chile and Argentina . The tapeworm itself needs two hosts in its life cycle. These are large domestic rodents ( Paka , Agutis , Pakarana ) as intermediate hosts and the forest dog as final host , whereby domestic dogs are also infested here, which become infected by feeding on hunting residues and now transmit the tapeworm to humans.
The disease caused by E. vogeli is polycystic echinococcosis (PE) . In this form of echinococcosis , the affected organs, mostly the liver, have many blisters that are similar to alveolar echinococcosis and cystic echinococcosis and are therefore morphologically regarded as an adaptation of E. vogeli to its large rodent hosts. The E. vogeli tapeworm is responsible for most cases of polycystic echinococcosis. The cause is believed to be that its main hosts are wild dogs who do not bury their droppings. The second pathogen, E. oligarthra , primarily affects cats that bury their faeces. Therefore, there is a greater chance for humans to come into contact with the eggs of E. vogeli and to become infected.
