Avian Leukosis Virus Subgroup J in Layer Chickens, China
To the Editor: In recent years, cases of avian leukosis virus subgroup J (ALV-J) infection and tumors in commercial layer chickens and breeders of egg-type chickens have been emerging in the People’s Republic of China. ALV-J was fi rst isolated from meattype chickens with myeloid leukosis in 1988. Although egg-type chickens have been experimentally infected with ALV-J to induce tumors (1), fi e...
متن کاملAberrant expression of liver microRNA in chickens infected with subgroup J avian leukosis virus.
Subgroup J avian leukosis virus (ALV-J) is an oncogenic retrovirus primarily causing myeloid leukosis (ML) in broilers. Although ALV is well under control in a few countries including the USA, poultry industry in many parts of the world continues suffering from serious economic loss due to sporadic or widespread ALV infection, especially ALV-J infection. ALV-J infection of chickens is reportedl...
متن کاملInvestigations of Avian Leukosis Virus Subgroup J and Reticuloendotheliosis Virus Infections in Broiler Breeders in China
Avian leukosis virus subgroup J (ALV-J) and reticuloendotheliosis virus (REV) were detected in Arbor Acres (AA) parent broiler breeders between September 2008 and December 2009 in China. Samples from blood (n=1331) and sick chickens (n=152) were obtained from 19 flocks in China for serology, histopathology and PCR analysis. Serologic analysis revealed that the anti-ALV-J, -REV or -ALV-J and REV...
متن کاملSerologic profile of avian leukosis virus subgroup-J, Mycoplasma gallisepticum and Mycoplasma synoviae in broiler grandparent flocks of Iran.
Avian Leukosis Virus Subgroup-J (ALV-J). Mycoplasma gallisepticum (MG) and MycopJasma synviae (MS) are important pathogens in chickens that cause severe economical losses in poultry industry throughout the world. Seven broiler grandparent flocks of Iran (six broiler strains) were sampled randomly at the ages of 8-63 wk (100 samples from each flock) for antibody detection to ALV-J, MG, and MS ...
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 ...
