Methods for evaluating and developing commercial chicken strains free of endogenous subgroup E avian leukosis virus.
The genome of nearly all chickens contains various DNA proviral insertions of retroviruses of subgroup E avian leukosis virus (ALVE). However, the elimination or control of ALVE gene expression is desirable to improve productivity, to improve resistance to avian leukosis virus (ALV)-induced tumours, and to develop safer live virus vaccines in chick embryos and cultured chick cells. Restriction ...
متن کاملEvidence of Avian Leukosis Virus Subgroup E and Endogenous Avian Virus in Marek’s Disease Vaccines Derived from Chicken Embryo Fibroblasts
The aim of this study was to detect and characterize the endogenous ALVs in cell associated MD vaccine. Chicken embryo fibroblast cell associated Marek’s disease vaccine was tested for possible contamination with Avian Leukosis Viruses (ALVs). Initially the vaccine cell lysate was tested for presence of group specific antigen (p27) of ALVs by ELISA and found positive for GSA. Subsequently total...
متن کاملEvidence of avian leukosis virus subgroup E and endogenous avian virus in measles and mumps vaccines derived from chicken cells: investigation of transmission to vaccine recipients.
Reverse transcriptase (RT) activity has been detected recently in all chicken cell-derived measles and mumps vaccines. A study of a vaccine manufactured in Europe indicated that the RT is associated with particles containing endogenous avian retrovirus (EAV-0) RNA and originates from the chicken embryonic fibroblasts (CEF) used as a substrate for propagation of the vaccine. We investigated the ...
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 ...
متن کاملA novel subgroup of exogenous avian leukosis virus in chickens.
An avian leukosis virus with a wide host range belonging to a new subgroup for chickens was isolated from meat-type chicken lines. The virus, of which HPRS-103 strain is the prototype, was of low oncogenicity in chickens but appeared to behave like an exogenous leukosis virus. Neutralizing antibodies to the virus were found in three of five meat-type chicken lines, but not in seven layer lines....
