. The pathology and differential diagnosis of infectious diseases of animals : prepared for students and practitioners of veterinary medicine . Veterinary medicine; Communicable diseases in animals. 262 ACTINOMYCOSIS can be found. If the pus is spread in a thin layer on a smooth surface granules composed of the organism can often be seen with the unaided eye. These pus cavities are usually connected with each other by small sinuses but sometimes they are separated by bands of fibrous tissue. If the disease is in the bone as it is when the specific organism gains entrance and begins to grow in the interior of the jaw, the bone tissue about the organism becomes in places disintegrated and absorbed and pockets are formed containing the granules. While the interior of the. Fig. 58. actinomycotic nodules in the nasal cavity ot a six yeab old cow. (after joest) . bone is being broken down and absorbed by the action of the actino- mycotic growth within, its diameter is being increased by the invasion and deposition of new material until it may become several times its normal size. The lesions spread in most cases by gradual invasion of the tissues surrounding the infected point. At the seat of infection, minute, inflammatory points appear, which extend at their periphery and unite to form larger areas of diseased tissue. These masses tend to extend in one direction and to heal in another, leaving behind bands of cicatricial tissue. The process usually differs widely from that of a simple inflammation. In its progress the disease shows no preference for structures but invades one tissue after another so that all may be involved Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Moore, Veranus A.
