Abstract: 

Objective: Comparison of the effects of buffalo-originated Echinococcus granulosus egg and onchosphere antigens in preventing the establishment and development of hydatid cysts in buffalo.
Design: Clinical trial.
Animals: Nine male buffalo calves, 7-8 months of age.
Procedure: Collection of E.granulosus from dogs, orally infected with buffalo-originated viable protoscoleces, separation of eggs from the gravid proglottids, culture of eggs and collection of activated onchospheres, sonication the eggs and onchospheres and preparation their homogenized antigens, intramuscularly injection of each of these antigens, mixed with complete Freunds adjuvant (CFA) to two groups of 3 buffaloes, first injection of PBS plus CFA to controls, second injection,with the same materials to the cases and controls, after 6 weeks, challenging each case and control with 500 E.granufosus eggs and staughtcrfng afl 6uMafocs after t0 months.
Statistical analysis: Analysis of variance, tukey test.
Results: The numbers of liver and lung hydatid cysts were significantly smaller than those of controls. Intestinal protection due to egg and onchosphere antigens was 84.5% and 89% respectively. Site protection of liver and lung against hydatid cyst establishment, achieved by the egg and onchospherc antigens were 45.3% and 53.37% respectively. Immunological protection due to egg and onchosphcre antigens was 76.7% and 83.5% respectively, too.
Conclusion: Antigens derived from the E. granulosus eggs and onchospherc are able to protect buffaloes against hydatidosis, although the protection potential of activated onchosphere antigen is much higher than the egg antigen.
