چکیده
A significant protection provided by maternal antibodies against avian adenovirus serotypes 8 and 11, previously associated with the inclusion body hepatitis and hydropericardium syndrome, was observed in breeder progenies after challenge at 1 and 7 days of age. At two weeks of age, in the presence of low maternal antibodies against avian adenovirus (AAV), chicken anemia virus (CAV) and infectious bursal disease virus (IBDV), birds from the same progenies were challenged with either the FAV serotype 8, a field CAV strain and/or the IBDV Edgar strain. The level of protection against clinical disease was evaluated in these progenies.

Infectious bursal disease virus (IBDV) in turkeys may result in immunosuppression, and inability of turkeys to resist nonpathogenic or less pathogenic organisms. A total number of 120 day-old commercial male turkeys were purchased and blood samples were collected from 20 day-old turkeys, remaining 100 were divided into four equal groups and kept in separated rooms. Groups 1 and 2 were infected ...

متن کاملThe effects of avian leukosis virus subgroup J on broiler chicken performance and response to vaccination.
The effects of avian leukosis virus subgroup J (ALV-J) infection on meat-type chickens reared in a simulated commercial setting were evaluated. Each of three ALV-J isolates was evaluated with both simulated horizontal transmission (SHT) and simulated vertical transmission (SVT). Mortality, morbidity, disease condemnations, and feed conversions were increased and body weights at processing were ...
