Multicentric 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 کاملInnate Immune Responses in ALV-J Infected Chicks and Chickens with Hemangioma In Vivo
Avian leukosis virus subgroup J (ALV-J) infection can cause tumors and immunosuppression. Since the precise mechanism of the innate immune response induced by ALV-J is unknown, we investigated the antiviral innate immune responses induced by ALV-J in chicks and chickens that had developed tumors. Spleen levels of interleukin-6 (IL-6), IL-10, IL-1β, and interferon-β (IFN-β) were not significantl...
متن کاملVertical transmission of avian leukosis virus subgroup J (ALV-J) from hens infected through artificial insemination with ALV-J infected semen
BACKGROUND Avian leukosis virus (ALV) is one of the main causes of tumour development within the poultry industry in China. The subgroup J avian leukosis viruses (ALV-J), which induce erythroblastosis and myelocytomatosis, have the greatest pathogenicity and transmission ability within this class of viruses. ALV can be transmitted both horizontally and vertically; however, the effects of ALV in...
متن کاملDetection 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 کاملIntegrated host and viral transcriptome analyses reveal pathology and inflammatory response mechanisms to ALV-J injection in SPF chickens
Avian leukosis virus (ALV) is detrimental to poultry health and causes substantial economic losses from mortality and decreased performance. Because tumorigenesis is a complex mechanism, the regulatory architecture of the immune system is likely to include the added dimensions of modulation by miRNAs and long-noncoding RNA (lncRNA). To characterize the response to ALV challenge, we developed a ...
