Six-month-old SPF Brown Leghorn cockerels were experimentally infected per os with S typhimurium (1 times 1010) and slaughtered at intervals up to 42 days following infection. Observations were made on the clinical pathology, bacteriology and serology during the course of infection and extensive bacteriological examinations were undertaken after post mortem examination.

The rat dominant hairless gene (Ht) of the WBN/Ila-Ht rat causes atrichosis in Ht/Ht and hypotrichosis in Ht/+. Furthermore the Ht/Ht shows signs of abnormal keratinization and almost all of the Ht/Ht die in an immature stage before weaning in the conventional environment. Ht/+ was affected by dermatitis caused by Staphylococcus aureus, suggesting that the gene Ht might involve defense mechanisms against infection. In this study, we performed the linkage analysis of the gene Ht by outcross with the Brown Norway rat in the SPF environment. Ninety-six backcross progeny of (BN x WBN/Ila-Ht/Ht) F1 x WBN/Ila-Ht/Ht were typed with microsatellite markers and the gene Ht was mapped on chromosome 10 between Asgr1 and Nos2 within the map distance of 6.2 cM.

Foci of haemopoiesis were found in the peripheral nerves of SPF Rhode Island Red chickens and conventionally reared Brown Leghorn chickens. They contained cells which closely resembled the development stages in the bone marrow of erythrocytes, heterophil leukocytes or thrombocytes, but did not include lymphocytes. When birds from these flocks are used to study neuropathological disease, ectopic haemopoiesis in nerves must be distinguished from pathological lesions.

Subgroup J avian leukosis virus (ALV-J), first isolated in 1989, predominantly causes myeloid leukosis (ML) in meat-type or egg-type chicken. Since 2006, the clinical cases of hemangioma rather than ML in commercial layer flocks associated with ALV-J have been reported, but it was still not clear whether the novel oncogenic ALV-J had emerged. We characterized SCAU-HN06 isolate of ALV-J from hemangioma in commercial Roman layers through animal experiment and full-length proviral genome sequence analysis. The SPF white leghorn egg-type chickens infected with SCAU-HN06 in ovo at day 11 of incubation showed an overall incidence of 56% hemangioma and 8% renal tumor throughout the 22-week trial, the mortality rate was 16%. Most genes of SCAU-HN06 isolate showed high nucleotide sequence identity to JS09GY6 which was isolated from Hy-Line Variety Brown layers suffering hemangioma. The 19-bp insertion in leader sequence and one key deletion in E element were the common features of SCAU-HN06 and JS09GY6. SCAU-HN06 and those ALV-Js associated with hemangioma, possibly recombinants of ALV-J and other avian retrovirus, may share the same ancestor.
