Diseases of cattle, sheep, goats Diseases of cattle, sheep, goats and swine diseasesofcattl00mous Year: 1905 Fig. 36. — Eggs of pork- measle tapeworm {Tcsnia sol'kwi) : a, with primi- tive vitelline membrane ; 6, without primitive vitel- line membrane, but wdth striated embry ophore. X 450. (After Leuckart.) cysticerci, but the uncertainty in this respect should prevent such meat being consumed. The cysticerci are killed at a temperature of 125° to 130° Fahr. Lesions. The lesions are represented by cysts alone—, by semi-transparent bladders, each of which contains a scolex or head armed with four suckers and a double crown of hooks. The httle bladders are most commonly found in the muscles, lodged in the interfascicular tissue, which they slightly irritate. The number present varies extremely, depending on the intensity of infestation and the number of eggs swallowed. Whilst in some cases difficult to discover, in others they are so numerous that the tissues ai3pear strewn with them. They are commonest in the muscles of the tongue, neck, and shoulders, in the intercostal and psoas muscles, and in those of the quarter. The viscera—viz., the liver, kidneys, heart, lungs, etc.—are less commonly in- fested, and in these organs the cysts degenerate very rapidly. In animals which have been infested for a long time, the cysts may even have undergone caseo- calcareous degeneration, the liquid being absorbed and the lesions presenting the appearance of little oblong firm nodules. On cutting through masses of muscle the vesicles protrude from between the bundles. In young animals, infestation with cysticerci causes wasting and ill-health; subsequently the patients improve in appearance, later on fatten, and gain marketable condition. Of the carcases examined in Prussian slaughter-houses between 1876—82, one in every 305 was found infested; between 188593, one in every 537.
