@entity195 has been detected in nine unrelated, commercial rabbitries. During the acute stage of the disease, recently weaned @entity95 showed profuse watery @entity294 . Mortality was between 14.2 and 41.2% during the first three weeks of the outbreaks. In surviving animals, there was a chronic evolution with @entity308 , @entity448 , loss of weight and sometimes extreme @entity3085 . Reproduction animals were less badly affected. Multifocal @entity99 , focal @entity296 , patches of @entity39 in ileum, caecum and colon and marked caecal @entity4 were most prominent at autopsy. In histological sections of the liver, bundles of slightly Gram-negative and Giemsa-, PAS- and @entity575 -positive rod-shaped bacilli were established in apparently viable hepatocytes bordering foci of @entity39 . They were also present in myocytes around @entity39 foci in the heart and in enterocytes and smooth muscle cells of the muscularis mucosae of the intestinal mucosa. Transmission electron microscopy showed that these organisms had a similar ultrastructure as Bacillus piliformis. Most antibiotics used failed to combat the disease. Only @entity5385 was active.
