A brief review is made of previous reports of neoplasms of the bovine mammary gland. A fibrosarcoma of the udder of a 4-year-old Ayrshire cow is described. The tumour was well circumscribed, had a number of multinucleate giant cells and mitoses, and invaded venules but had no metastasis. The serum glutamic oxalacetic transaminase activity was elevated.

A congenital progressive myopathy affecting 2% of a flock of Merino sheep involved most of the muscles of the pelvic and pectoral girdles. The vastus intermedius muscle was consistently affected; at 2 years of age 50% of its fibers were replaced by fat and at 5 years almost all. Lesions were bilaterally symmetrical. Usually all components of the quadriceps muscle were involved, but scattered affected fibers were found in most other appendicular muscles. The lesions in the quadriceps muscles resulted in inability to flex the femoro-tibial joint, with consequent difficulty in locomotion, which, under range conditions, resulted in death from inability to forage. Histologically, affected muscles had rounded fibers with central and peripheral sarcoplasmic masses. The fibers contained vesicular nuclei that usually formed rows of up to 15, but occasionally up to 50. In 6-week-old lambs, muscle fibers ranged in diameter from 15-100 μ. No lesion was detected in the peripheral or central nervous system.

The pathology of bovinc livers during the parenchymal and chronic phases of natural Fasciola hepatica infections is described. Immature infections occurred from September to the middle of January. Significant changes of the hepatic parenchyma caused by immature flukes occurred in association with large migrational tracks. The changes included frequent thrombosis and haemorrhages, extensive disintegration and coagulative necrosis of hepatic cells, and abundant infiltrates of inflammatory cells. In chronic infections the proliferation and destruction of the mucosa of main bile ducts were pronounced. Normal mast cells were lacking in the portal areas surrounding fresh migrational tracks. In chronically infected livers mast cells occurred in great numbers.

Three locoweeds, Oxytropis sericea, Astragalus pubentissimus, and A. lentigimosus were fed experimentally to yearling wethers for 60 days. Clinical signs were central nervous impairment resulting in diminished control or loss of motor function and proprioception. Cytoplasmic vacuolar degeneration was a constant finding in the neurons of the central nervous system, and of the plexuses of Auerbach and Miessner. Cytoplasmic vacuoles were also present in reticuloendothelial cells, liver, kidney, and other parenchymatous organs. The contents of the vacuoles was not determined.

The pattern of acute enteritis in captive cottontail rabbits was observed over a 4-year period and was found to repeat itself within close limits in each of the 4 years. Mortality exceeded 50% in those rabbits caged individually, and the clinical course was about 24 hours. Major pathological changes were limited to the stomach and large gut with necrosis, edema, and loss of mucosa. Severe dehydration was the probable cause of death in most cases. The disease bears clinical and pathological similarity to mucoid enteritis in domestic rabbits. Epidemic patterns suggest that an infectious agent may be involved.

Durch vergleichende licht- und elektronenmikroskopische Untersuchungen am übertragbaren venerischen Sarkom und Histiozytom des Hundes, können verschiedene morphologische Unterscheidungsmerkmale aufgezeigt werden. Lichtmikroskopisch sind beim venerischen Sarkom deutliche Zellabgrenzungen und zahlreiche Mitosen (5,31 ± 2,58 pro Blickfeld bei 320facher Vergrösserung), beim Histiozytom meist nicht sichtbare Zellgrenzen und wenige Mitosen (1,39 ± 1,96 pro Blickfeld bei 320facher Vergrösserung) zu beobachten. Die Differenz der Mitosenmittelwerte beider Tumoren ist hoch significant p < 0,001. Elektronen-mikroskopisch lässt das venerische Sarkom eine typische Anordnung der Mikrovilli erkennen, indem in schmalen Interzellularspalten zahlreiche, incinander verflochtene und der Zellmembran dicht anliegende mikrovilliartige Ausstülpungen zu finden sind, die das Bild eines interzellulären Lamellensystems vermitteln. Diese Anordnung der Mikrovilli, die beim Histiozytom niemals zu beobachten ist, wird für die lichtmikroskopisch deutliche Zellabgrenzung beim venerischen Sarkom verantwortlich gemacht. Weiterhin zeigt das Histiozytom im Gegensatz zum venerischen Sarkom häulig eine hochgradige vesikuläre Transformation des glatten endoplasmatischen Retikulums und eine paranukleäre Lagerung der Zyto-plasmaorganellen.

Histological examination of epiphyseal cartilages from 36 clinically normal, immature pigs of varying age, sex, and breed, revealed a high incidence of cosinophilic streaking and patches, irregularity in the length of columns of chondrocytes, disturbances in the metaphyseal blood supply to the plate, and local abnormalities in cartilaginous growth. It is concluded that these change are pathological, but not a cause of ‘leg weakness’ in pigs.
