Adenoviral gizzard erosions in Italian chicken flocks.
TYPE 1 avian adenoviruses belong to the genus Aviadenovirus within the adenovirus family. Five species of fowl adenovirus (fAdV) (designated by the letters A to E) are recognised within the Aviadenovirus genus based largely on molecular criteria, in particular restriction enzyme fragmentation patterns and sequencing data (McFerran and McConnel Adair 2003). fAdV are common infectious agents in p...
متن کاملGenome Sequence of Fowl Aviadenovirus A Strain JM1/1, Which Caused Gizzard Erosions in Japan
This study reports the complete genome sequence of fowl aviadenovirus A strain JM1/1, which caused gizzard erosions in broilers occurring in Japan. The JM1/1 genome is 43,809 bp in length and most closely related to the strain chicken embryo lethal orphan (CELO); moreover, multiple site insertions and deletions were found.
متن کاملA chronicle of serologic response in commercial layer chickens to vaccination with commercial F strain Mycoplasma gallisepticum vaccine.
Vaccination of multi-age layer operations, wherein one million plus commercial layer chickens are housed, has been spurious until the development of a self-propelled, constant-speed spray vaccinator. Still, even with its use, live Mycoplasma gallisepticum (MG) vaccinations have been questionable in terms of seroconversion. Using the vaccinator as a research tool over the past 5 yr, factors have...
متن کاملInfluence of Bile Acids on Erosions of the Chick Gizzard Lining.
EXPERIMENTAL results indicating the necessity of an organic dietary factor for the maintenance of a normal gizzard lining in the chick, and the prevention of erosions or lesions of the lining have been given in a number of papers."1 2, 3 4 A series of experiments on the role of the bile acids in this deficiency disease may now be reported. The feeding of whole bile by oral administration or by ...
متن کاملMicrosatellite markers associated with resistance to Marek's disease in commercial layer chickens.
The objective of the current study was to identify QTL conferring resistance to Marek's disease (MD) in commercial layer chickens. To generate the resource population, 2 partially inbred lines that differed in MD-caused mortality were intermated to produce 5 backcross families. Vaccinated chicks were challenged with very virulent plus (vv+) MD virus strain 648A at 6 d and monitored for MD sympt...
