摘要:
SummaryThe ‘arc 5’ precipitin band, formed when test human serum is reacted against immunoelectrophoresed hydatid cyst fluid antigen, has provided a positive diagnosis of Echinococcus granulosus infection. These antibodies to ‘arc 5’ antigen have now been found in the sera of sheep. They appear 2 weeks after infection with Taenia ovis, after 3 weeks with T. hydatigena and after 16 weeks with E. granulosus.An antigen similar to the ‘arc 5’ antigen of E. granulosus cyst fluid was also demonstrated in cyst fluid from T. hydatigena, but it could not be positively identified in T. ovis cyst fluid. The presence of ‘arc 5’ in immunoelectrophoresis tests is not suitable for specific immunodiagnosis of E. granulosus infections in sheep in New Zealand.‘Arc 5’ antibodies were only associated with living E. granulosus cysts and were not present if cysts were dead. The location of the cysts in either liver or lungs and the onset of brood capsule production did not influence the presence of
