Echinococcus granulosus antigen B and seroreactivity in natural ovine hydatidosis

摘要: Hydatid cyst fluid from sheep and camels infected with Echinococcus granulosus, together partially purified preparations of hydatid antigen B a recombinant product, were tested in an ELISA for their ability to detect IgG antibodies against E granulosus the serum naturally sheep. The antibody activity sera Taenia hydatigena cysticercosis or Fasciola hepatica was also tested. All native able significant proportion natural infection, as identified by inspection at slaughter, although seroreactivity variable. preparation camel gave highest sensitivity (total 90 per cent), 99 cent specificity. In all cases, least sensitive (25 cent) it highly specific (99 cent).
