Detection of avian leukosis virus subgroup J in albumen of commercial and native fowl eggs using RT-PCR in Fars province of Iran
The subgroup J of ALV (ALV-J) has emerged as an important pathogen of meat-type chickens since1989. This virus is responsible for economic losses due to both mortality and depressed performance inchickens. So, the objective of this study is the detection of ALV-J in the albumen of commercial and nativefowl eggs using RT-PCR. Three hundred and seventy egg albumens were randomly selected from dif...
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 کاملAvian 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 کاملDetection and Molecular Characterization of J Subgroup Avian Leukosis Virus in Wild Ducks in China
To assess the status of avian leukosis virus subgroup J (ALV-J) in wild ducks in China, we examined samples from 528 wild ducks, representing 17 species, which were collected in China over the past 3 years. Virus isolation and PCR showed that 7 ALV-J strains were isolated from wild ducks. The env genes and the 3'UTRs from these isolates were cloned and sequenced. The env genes of all 7 wild duc...
