Application of lentinan in suppression of Marek's disease virus infection [PDF]

Poultry Science
Marek's disease virus (MDV) is an extremely widespread avian immunosuppressive virus. In recent years, many reports have shown that there are still cases of MDV infection and immunosuppression after immunization with the vaccine. Consequently, there is a

Amino acid insertion in the Meq protein of Marek’s disease virus, an avian oncogenic herpesvirus, accelerates tumorigenesis [PDF]

Microbiology Spectrum
Marek’s disease virus (MDV) causes lymphomas (Marek’s disease) in chickens. Despite vaccination, MDV field strains exhibit increased virulence, and sporadic outbreaks are still reported.

Viral miRNA delivered by exosomes from Marek's disease virus-transformed lymphoma cell line exerts regulatory function in internalized primary chicken embryo fibroblast cells [PDF]

Tumour Virus Research
In the past decade, research has demonstrated that viral miRNAs encoded by a number of viral genomes, particularly by most of the herpesvirus including Marek's disease virus (MDV), play important regulatory roles in viral infection, replication, and ...

Overexpression of Interleukin-17 Modulates Responses to Marek’s Disease Virus Infection and Tumor Formation in Chickens [PDF]

Viruses
Marek’s Disease Virus (MDV) is a highly contagious pathogen in chickens, resulting in immunosuppression and T-cell lymphomas. Understanding the role of host cytokines in MDV pathogenesis is crucial for developing effective interventions.

The Regulatory Microenvironment in Feathers of Chickens Infected with Very Virulent Marek’s Disease Virus

Viruses, 2022
Vaccines against Marek’s disease can protect chickens against clinical disease; however, infected chickens continue to propagate the Marek’s disease virus (MDV) in feather follicles and can shed the virus into the environment.

PREVALENCE OF TUMOURS AMONG POULTRY FLOCKS IN EGYPT [PDF]

Assiut Veterinary Medical Journal, 1999
Tumours were found to be responsible for deaths at rates of 11%, 5%, 1.2%, and 3% in native breed chicks, layers, broilers, and broiler breeders respectively. Sera and egg-albumen were monitored for presence of P-27 common antigen of avian leukosis virus

Analysis of DNA methylation of CD79B in MDV-infected chicken spleen

Journal of Integrative Agriculture, 2021
Marek's disease (MD), an immunosuppressive disease induced by Marek's disease virus (MDV), provides an ideal model for studying diseases caused by a carcinogenic virus. CD79B is a B-cell antigen receptor complex-associated protein β-chain precursor which

Occurrence of Marek’s disease in Poland on the basis of diagnostic examination in 2015–2018

Journal of Veterinary Research, 2020
Marek’s disease (MD) is a tumourous disease caused by Marek’s disease virus (MDV) and most commonly described in poultry. The aim of the study was to determine the occurrence of Marek’s disease virus infections in Poland and analyse clinical cases in the
