Experimental infection of sheep with hydatids

Extract

Sir, — Readers of “Problems in Hydatid Eradication” (N.Z. vet. J. 28: 211, 1980) may have gained the impression that Wallaceville is a source of hydatid infection. However, the experiments alluded to took place at Wallaceville's Hydatid Field Unit on the Taieri Plain, Otago, and not at Wallaceville itself (the mis-report occurred in a MAF bulletin which I assume was your information source). Also, “hydatids” signified Taenia hydatigena and not Echinococcus granulosus (the experimental details can be found in Gemmell, Johnstone and Boswell, Res vet. Sci. 24: 334–338, 1978).
