Archive image from page 224 of The pathology and differential diagnosis The pathology and differential diagnosis of infectious diseases of animals differentpathology00moorrich Year: 1908 MORBID ANATOMY contain calcareous salts. General- ization is common, in which case the viscera are thickly sprinkled with gray granulations which are translucent throughout, or opaque in their centers, and quite analo- gous to those found in tubercular lesions in other animals. As the disease most often re- sults from ingestion of the virus, the digestive apparatus and the cor- responding lymphatic glands (sub- maxillary, parotid, pharyngeal, su- perior cervical, mesenteric, sub- lumbar, etc.) may be decidedly diseased, while the other organs re- main practically intact. Lesions of the small intestine and of the cecum are common and take the form of ulcers of the mucous mem- brane, of miliary nodules or of tuberculous infiltrations, involving at once the mucous, the muscular, and subserous tissues. The lesions in the liver take the form either of miliar\' granulations, which are yellow and caseous and scattered in great numbers through the thick- ness of the organ, or else of rounded nodules which are yellowish white in color, varying in size from that of a pea to a hazel nut and of a tough consistency. On section they appear sometimes to be firm, homogeneous and fibrous ; some- times .softened in the center, often infiltrated with calcareous salts. The peritoneum and the Fig. 44.
