Isolation, Molecular Characterisation, and Pathogenicity Analysis of a Novel Recombinant ALV‐J Strain Isolated From Chinese Hetian Chickens

Veterinary Medicine and Science, Volume 10, Issue 6, November 2024.
Reduced mortality: The isolated LY2021J strain of ALV‐J from Hetian chickens showed lower mortality despite causing severe dysplasia. Genetic similarity: LY2021J exhibited high genetic similarity to the Chinese Heilongjiang strain JS14NT01, particularly in the gp85 and pol genes, suggesting a possible common origin.

CH25H Promotes Autophagy and Regulates the Malignant Progression of Laryngeal Squamous Cell Carcinoma Through the PI3K‐AKT Pathway

Cancer Medicine, Volume 13, Issue 20, October 2024.
ABSTRACT Background Laryngeal squamous cell carcinoma (LSCC) is a type of cancer of the respiratory tract that often presents with subtle symptoms at the early stage and is susceptible to recurrence and metastasis. Materials and Methods To find out key regulatory genes involved in LSCC development, we downloaded LSCC‐related sequencing datasets for ...

DETEKSI DINI PENYAKIT TUMOR SEL DARAH MYELOSIT LEUKOSIS MELALUI PEMERIKSAAN ULAS DARAH

Jurnal Ilmu Pertanian Indonesia, 2007
Myelocytes blood cell tumor in chicken is a disease caused by retrovirus, avian leukosis virus subgroup J (ALV-J). The virus has the same group as human retrovirus (HIV) which caused AIDS, but the avian type possesses oncogenic properties, that could ...

Detection of ALV p27 in cloacal swabs and virus isolation medium by sELISA

BMC Veterinary Research, 2019
Background Avian leukosis (AL), which is caused by avian leukosis virus (ALV), has led to substantial economic losses in the poultry industry. The kit used to detect all ALV-positive chickens in breeder flocks is very important for efficiently ...

Tumour or haemorrhage?: Differential diagnosis of an unknown mass within the brain of a budgerigar (Melopsittacus undulatus) using a novel imaging pipeline

Veterinary Record Case Reports, Volume 12, Issue 3, September 2024.
Abstract We report on a previously healthy zoo specimen of an adult budgerigar (Melopsittacus undulatus, obtained with permission from Southwick's Zoo) found deceased in its enclosure. To assess cause of death and ensure the absence of an infectious neoplasia, we used an integrated multiscale brain‐imaging workflow, previously only used on mammals. The

Naturally Occurring Co-infection of Avian Leukosis Virus (subgroups A-E) and Reticuloendotheliosis Virus in Green Peafowls (Pavo muticus)

Brazilian Journal of Poultry Science
Most of the neoplastic diseases affecting poultry have a viral etiology, such as Marek’s disease, avian leukosis/sarcoma and reticuloendotheliosis. In the present paper, histopathology and molecular methods were performed, in addition of necropsy and ...

The Complement-fixation Test for Avian Leukosis

Journal of General Virology, 1968
Summary Sera from hamsters bearing tumours induced by the Schmidt-Ruppin strain of Rous sarcoma virus (sr-RSV) contain antibodies to the avian leukosis group specific antigen and an antigen of chick origin. The ‘chick embryo antigen’ is found in chick embryos infected and uninfected with avian leukosis viruses and in chicken tumours induced by avian ...

Pathological and immunohistochemical studies of lymphoid leukosis in pigeons in Egypt

Open Veterinary Journal
Background: Pigeon leukosis is primarily caused by avian leukosis virus subgroup A (ALV-A). It infects and transforms lymphoid cells, leading to the development of tumors in various lymphoid tissues and other organs especially the liver.

Vertical transmission of avian leukosis virus subgroup J (ALV-J) from hens infected through artificial insemination with ALV-J infected semen

BMC Veterinary Research, 2017
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
