The Echinococcus granulosus diagnostic arc 5 was revealed by sera from an Alaskan and a Swiss patient with surgically confirmed E. multilocularis infections. The possibility of each patient harboring a concurrent infection with both parasites may be disregarded on the basis of radiologic, scintillographic and surgical data. This conclusion is compatible with ecologic and epidemiologic considerations. These observations suggest that the immunoelectrophoresis test based on arc 5 positivity is not E. granulosus-specific as originally described.
阿拉斯加和瑞士两名经手术确诊为多房棘球绦虫感染的患者血清显示出细粒棘球绦虫诊断性弧5。根据放射学、闪烁扫描和手术数据，可以排除每位患者同时感染这两种寄生虫的可能性。这一结论与生态学和流行病学考虑因素相符。这些观察结果表明，基于弧5阳性的免疫电泳试验并非如最初描述的那样具有细粒棘球绦虫特异性。
