. Common diseases of farm animals. Veterinary medicine. 314 INFECTIOUS DISEASES hind limbs and are known as " farcy ; Lymphatic vessels near these buds become swollen and hard. The animal loses flesh rapidly, does not withstand hard work, and the limbs usually swell. It is sometimes difficult to diagnose the disease. The ulcers on the nasal mucous membranes and elsewhere are very charac- teristic, and when present enable the examiner to form a diag- nosis. In cases of doubt, a bacteriological examination of the nasal discharge may be made, or we may resort to one or several of the various diagnostic tests. The Mallein test is quite commonly used. The sterilized products of a culture of the B. mallei are injected beneath the skin of the suspected animal. This causes a rise in body temperature and a hot, characteristic swelling at the point of I injection in glandered animals- Treatment is not recommended at the present time. ISTearly all of the States have laws which aim to stamp out the disease wherever found by Fia. na.—streptococcus pyogenes killing all afi"ected animals, and thor- ^""'^ oiigbly disinfecting the stables, har- ness and everything which has been near the animal. Dis- eased animals should be carefully isolated until slaughtered, and all animals exposed to them should be subsequently tested for glanders. Contagious Pleuropneumonia (Stable Pneumonia).—This is an infectious disease of solipeds that usually results in a fatal inflammation of the lungs and pleural membrane. Many writers have described this disease as associated with influenza, but it is frequently seen as a separate disease, usually involving only the lungs and pleurae. It is prevalent in several parts of the United States, more particularly the horse centers or large markets, where it appears in the form of Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration a
