Studies on hydatid cyst fluid antigens in livestock

By using double diffusion test, some differences were observed between whole hydatid fluid antigens derived from camel, sheep and cattle. The previously mentioned antigens reacted with the hyperimmune serum prepared against whole hydatid cyst fluid of camel and gave four, three and two lines, respectively. Hydatid antigen [5] was detected in whole hydatid cyst fluids of both sheep and cattle origin

Gross reactions between some helminthes infesting man and animals

Using double diffusion test, cross reactions were detected between Schistosoma mansoni and each of Fascial gigantica and Setaria equina adult worms antigens. Whole hydatid fluid antigen and hydatid antigens [4 and 5] reacted separately with Schistosoma mansoni, Fasciola gigantica and Setaria equina adult worms. No cross reactions were detected between hydatid antigen [5] and other mentioned helminths
