Exotic Newcastle Disease in a Game Chicken Flock

Avian Diseases, 43(2), 349.

author keywords: game chickens; avian paramyxovirus type 1; pathology; exotic Newcastle disease; virus isolation
TL;DR: A sudden increase in mortality, preceded by a short history of respiratory signs and diarrhea, occurred in a backyard flock of 48 game chickens in the Central Valley of California, and a thorough epidemiologic investigation was carried out, and no other premises were found to have birds with clinical signs or evidence of exposure.

author keywords: endosteal callus; femur fracture; periosteal callus; turkey
TL;DR: Periosteal callus formation in turkeys presented to the California Veterinary Diagnostic Laboratory System suggested that preexisting lesions preceded complete fracture of the femur, which might have contributed to the development and promotion of complete fractures. (via Semantic Scholar)

Development of the Thoracic Air Sacs of Turkeys with Age and Rearing Conditions

Avian Diseases, 42(1), 35.

author keywords: cilia; commercial; electron microscopy; epithelium; exfoliative cytology; guided fiberoptic endoscopy; histology; isolation; Meleagris gallopavo; microvilli; surfactant; thoracic air sac; turkey; type II pneumocytes
TL;DR: The air sacs of commercial turkeys had a larger proportion of ciliated epithelium than did those of isolation birds, which may protect against disease by a structured mucociliary transport system, the production of surfactant, and phagocytosis of foreign particles. (via Semantic Scholar)

Contributors: R. Crespo*, M. Taylor & D. Hunter

author keywords: blind sac; caudal thoracic air sac; cranial thoracic air sac; endoscope; invagination; Meleagris gallopavo; ostium; turkey
TL;DR: The gross anatomy of the cranial thoracic air sacs was studied in the live turkey with a fiber-optic endoscope fitted with a video system and revealed an invagination arising from the floor of the air sac that partially divided the single thoracIC air sac creating a blind-ended sac.

author keywords: air sac; anticoagulant; cell quality index; centrifugation speed; endoscope; fixative; lavage; Meleagris gallopavo; protein; temperature; time to processing; turkey
TL;DR: Optimal cell morphology was achieved when the sample was centrifuged at a speed of 1000 rpm (89.4 X g) and when prepared in less than an hour from the time of collection, and low temperature tended to preserve cell quality better. (via Semantic Scholar)
