[Chronic hepatitis in lambs (author's transl)].

When deaths and symptoms of chronic emaciation not due to any apparent cause occurred in weaned lambs, the morphological changes observed suggested that the liver probably was the main organ, the function of which was impaired. This was believed to be so because of the homogenity of the changes in this organ and the disseminated character of the lesions of the liver. These were termed chronic as secondary perilobular reactions occurred in addition to primary degenerative changes of the parenchyma, in which septa appeared in addition to lymphocytic infiltration in the portal triad. In view of the epidemiological findings, this heaptitis was believed to be infectious rather than toxic.
