molecular studies on avian leukosis virus subgroup j (alv-j) infections in grandparent flocks in iran
abstract: subgroup j avian leukosis virus (alv-j) was isolated in the late 1980s from meat-type chickens in the united kingdom. alv-j with exception of some acute variants, cause myeloid leukosis in meat-type chickens with long incubation period.in this study while the status of avian leukosis virus subgroup j in six different strain of broiler grandparent flocks of iran evaluated, the evaluati...
متن کاملInvestigations on the Presence of Antibodies to Avian Leukosis Virus Subgroup-J (ALV-J) in Broiler Breeders and Broilers
The aim of this study was to investigate the presence of antibodies to ALV-J in broilers and broiler breeders. For this, 5 broiler units and 1 broiler breeding unit in the Marmara region were visited. Seventy 4-6 -week-old chicks from the broiler units, consisting of 14 chicks from each broiler unit, were selected. Seventeen chickens from the broiler breeding unit were also selected. The chicks...
متن کاملMulticentric Histiocytosis Related to Avian Leukosis Virus Subgroup J (ALV-J)-Infection in Meat-Type Local Chickens
Gross lesions characterized by swollen livers and spleens accompanied by diffuse white miliary spots, which resembled those of Marek's disease, were detected in two flocks of local meat-type chickens at a Japanese poultry processing plant in June and August 2010. The microscopic examinations revealed proliferative foci consisting of spindle or polymorphic cells in the interstitium of livers, sp...
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 کاملMicroRNA-23b Promotes Avian Leukosis Virus Subgroup J (ALV-J) Replication by Targeting IRF1
Avian leukosis virus subgroup J (ALV-J) can cause several different leukemia-like proliferative diseases in the hemopoietic system of chickens. Here, we investigated the transcriptome profiles and miRNA expression profiles of ALV-J-infected and uninfected chicken spleens to identify the genes and miRNAs related to ALV-J invasion. In total, 252 genes and 167 miRNAs were differentially expressed ...
