The rupture of this tendon-muscle is exceptional, and, according to the description given by Furlanetto, is attended by the same symptoms as in the horse—_i.e._, flexion of the stifle joint is not accompanied by flexion of the hock or of the metatarsus on the tibia. The cannon bone hangs vertically when the limb is moved. Recovery follows prolonged rest. Wounds and sections of tendons in the region of the cannon bone, sections of the tendo-Achillis, etc., have been seen and described. All such injuries may heal under antiseptic treatment and after aseptic suture of the divided ends, provided the sutures and dressings are applied immediately. If, on the other hand, suppuration, infection, necrosis of tendons, synovitis or arthritis occur as complications, such injuries become extremely serious, and from an economic standpoint render it better to sacrifice the animal rather than attempt treatment. Strains of tendons and tendinitis occur in the front limbs of oxen, particularly of those used in carts. The chief indications are swelling in the region of the cannon bone and fetlock, uneven contour of the flexor tendons, sensibility on pressure, and lameness of varying intensity. =Treatment= consists in continuous cold irrigation, massage, the application of a blister or even of the actual cautery. As a rule, however, it is better to rest and fatten the animal. A frequent complication of such injuries of tendons consists in knuckling over at the fetlock. PARASITIC DISEASES OF MUSCLES. INFECTION WITH CYSTICERCI. Infection of the connective and muscular tissues with cysticerci results from the entry into the body of embryos of _Tænia solium_ and _Tænia saginata_ of man. It occurs in man and almost all animals, but is only of grave clinical importance in the pig and ox. The following table shows the chief cystic (cestode) parasites of animals, though the cysts are not always confined to muscular structures:— ┌─────────────────────────┬───────────────────────────────────────────┐ │ Adult. │ Larva. │ ├───────────────────┬─────┼───────────────────────┬───────────────────┤ │ Name. │Host.│ Name. │ Host. │ ├───────────────────┼─────┼───────────────────────┼───────────────────┤ │_Tænia saginata_ │Man │_Cysticercus bovis_ │Cattle. │ │_Tænia solium_ │Man │_Cysticercus cellulosæ_│Swine and man. │ │_Tænia marginata_ │Dogs │_Cysticercus │Cattle, sheep, and │ │ │ │ tenuicollis_ │ swine. │ │_Tænia cœnurus_ │Dogs │_Cœnurus cerebralis_ │Cattle and sheep. │ │_Tænia │Dogs │_Echinococcus │Cattle, sheep, │ │ echinococcus_ │ │ polymorphus_ │ swine, man, etc. │ └───────────────────┴─────┴───────────────────────┴───────────────────┘ CYSTICERCUS DISEASE OF THE PIG.
