• Hydatid bone disease is a zoonotic parasitic infection that is caused primarily by the tapeworm Echinococcus granulosus, and it continues to be a major public health concern in pastoral regions. (bvsalud.org)
  • The causative agent is the tapeworm Echinococcus granulosus, whose adult stage takes place in the small intestine of definitive hosts (dogs) and the development of the larval stage occurs mainly in the liver and lung of intermediate hosts such as sheep. (edu.pe)
  • Echinococcosis is a parasitic disease of tapeworms of the Echinococcus type characterized by production of unilocular or multilocular cystic disease of lung and liver. (capsulehealth.one)
  • While adult E. granulosus is harmless in dogs, the larval form can be a huge problem in humans. (wikipedia.org)
  • More recently, low prevalence in slaughterhouses was described in southern France (3 and 4 cases per 100,000 in cattle and sheep, respectively), and only E. granulosus sensu stricto larval tapeworms were identified ( 9 ). (cdc.gov)
  • Results of testing in a 63-year-old man from the Jura département (eastern France), who was diagnosed with infection with Echinococcus ortleppi larval tapeworms in 2001. (cdc.gov)
  • The locations of this protein in the adult worm and larval stage, and the mRNA expression in different states of E. granulosus protoscoleces (PSCs) were defined clearly. (qxmd.com)
  • El agente causante es el céstodo Echinococcus granulosus, cuyo estadio adulto se desarrolla en el intestino delgado de hospederos definitivos (caninos) y el desarrollo del estadio larval se presenta principalmente en el hígado y pulmón de hospederos intermediarios como el ganado ovino. (edu.pe)
  • Echinococcosis, caused by larval stage of the genus Echinococcus , is one of the most important zoonotic diseases worldwide. (cambridge.org)
  • Echinococcus granulosus, also called the hydatid worm, hyper tape-worm or dog tapeworm, is a cyclophyllid cestode that dwells in the small intestine of canids as an adult, but which has important intermediate hosts such as livestock and humans, where it causes cystic echinococcosis, also known as hydatid disease. (wikipedia.org)
  • Echinococcus granulosus is a harmful cestode parasite that causes cystic echinococcosis in humans as well as various livestock species and wild animals. (qxmd.com)
  • The purpose of this study was to determine the presence and prevalence of Echinococcus species in stray dogs of Erzurum, a highly endemic region for cystic echinococcosis (CE) and alveolar echinococcosis (AE) in Turkey. (cambridge.org)
  • Echinococci are platyhelminths of the cestode genus. (medscape.com)
  • Echinococcus granulosus is ingested and attaches to the mucosa of the intestines in the definitive host and there the parasite will grow into the adult stages. (wikipedia.org)
  • Although rare, the parasite can form a cyst causing cystic echinococcus also known as hydatid disease. (wikipedia.org)
  • Like all cyclophyllideans, E. granulosus has four suckers on its scolex ("head"), and E. granulosus also has a rostellum with hooks. (wikipedia.org)
  • A recent consensus on the terminology in the field of echinococcosis has fixed the names of the diseases, the various species of Echinococcus involved and several terms to be used in the scientific literature on the subject. (medscape.com)
  • We can't say which species of Echinococcus is present from the image alone, but it is most likely to be E. granulosus, as this is the most common species to infect humans, and it commonly forms a liver cyst that is amenable to aspiration. (blogspot.com)
  • E. granulosus s.s. was the most abundant species. (cambridge.org)
  • The lifecycle of E. granulosus involves dogs and wild carnivores as a definitive host for the adult tapeworm. (wikipedia.org)
  • E. granulosus requires two host types, a definitive host and an intermediate host. (wikipedia.org)
  • Eventually, the metacestodes are filled with protoscoleces, which, upon predation by a definitive host, lead to a new generation of adult worms in the definitive host's intestine. (biomedcentral.com)
  • Immunoblotting analysis revealed that rEgCaM could be identified using E. granulosus infected sheep serum. (qxmd.com)
  • In 2011 and 2012, liver infections caused by Echinococcus ortleppi tapeworms were diagnosed in 2 humans in France. (cdc.gov)
  • Therefore imnunoprotección was evaluated against E.granulosus using surface antigens as membrane proteins and metabolic products of excretion-secretion protoscoleces and adult worms. (edu.pe)
  • The protoscoleces that fill the microcysts transform into adult worms once ingested into the intestine of the carnivore host. (medscape.com)
  • E. granulosus sensu stricto (genotypes G1-G3), E. equinus (G4), E. ortleppi (G5), and E. canadensis (G6-G10) ( 3 ). (cdc.gov)
  • Humans can also be an intermediate host for E. granulosus, however this is uncommon and therefore humans are considered an aberrant intermediate host. (wikipedia.org)
  • Several strains of E. granulosus have been identified, and all but two are noted to be infective in humans. (wikipedia.org)
  • However, freezing at -18 °C for 6 and 9 h has been found to be very effective in killing all protoscoleces present in the hydatid liquids. (openveterinaryjournal.com)
  • These findings highlight a significant public health risk for human AE and CE, presenting useful baseline data on Echinococcus spp. (cambridge.org)
  • Echinococcus granulosus was first documented in Alaska but is distributed worldwide. (wikipedia.org)
