Proglottids passed by steer
A 7-month-old steer from southern California passed a number of small rectangular proglottids in his feces. When crushed and examined microscopically, each proglottid was found to contain a number of egg clusters, with each egg containing a set of six distinct hooks. What parasite is this?
This is Wyominia tetoni, a tapeworm of mountain sheep in the western United States that occasionally infects cattle. Effective treatments would be expected to be similar to those that are used for Moneizia sp. infections in cattle.
