*IBCF, antigen was bovine hydatid cyst fluid; rEpC1-GST, antigen was recombinant EpC1 glutathione S-transferase.
†Group of volunteers who came from nearby communities and were also included in the survey.
‡Statistically different (p<0.01), with higher percentage of seropositivity for rEpC1-GST than IBCF.
