First, the worms produce a local irritation of the intes- tine, which finally develops into a chronic catarrhal inflammation; their presence in the gall ducts produces similar results and obstructs the flow of bile; infected lambs are large headed, undersized, and hide- bound; their gait is rheumatic and they appear more foolish than the other sheep, standing of- tener to stamp at the sheep dogs or herders, and lag- ging behind the flock when driven; the general symp- toms are those of malnutri- tion, and Curtice considers them nearly identical with the symptoms of the loco disease; in fact, he states that it is extremely difficult to distinguish between the two diseases, and believes that the fact that the worms “may tend to produce de- praved appetites and a morbid craze for a particular food is also reason for suspecting that the loco disease may depend on the tape- worm disease.” General systematic disturbances result from malnu- trition; the usual fat is absent; serous effusions are noticed in the body cavities, serous infiltration in the connective tissue. Treatment. — Curtice found that powdered preparations of pumpkin seed, pomegranate-root bark, cusso, k am ala, male fern, and worm seed were of no avail, a failure due, he maintains, to the anatomical structure of the sheep’s stomach and method of administration; no medicine could be used to dislodge the parasites from the gall ducts. Personally, I have never but I would suggest the on pp. 133-135.
