A Review on the Marek’s Disease Outbreak and Its Virulence-Related meq Genovariation in Asia between 2011 and 2021

Animals, 2022
Marek’s disease is an infectious disease in poultry that usually appears in neural and visceral tumors. This disease is caused by Gallid alphaherpesvirus 2 infection in lymphocytes, and its meq gene is commonly used in virulent studies for coding the key

Effect of Insertion and Deletion in the Meq Protein Encoded by Highly Oncogenic Marek’s Disease Virus on Transactivation Activity and Virulence

Viruses, 2022
Marek’s disease virus (MDV) causes malignant lymphoma in chickens (Marek’s disease, MD). Although MD is currently controlled by vaccination, MDV strains have continuously increased in virulence over the recent decades.

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.

B cells do not play a role in vaccine-mediated immunity against Marek’s disease

Vaccine: X, 2022
Background: Marek’s disease virus (MDV), a highly oncogenic α-herpesvirus, is the etiological agent of Marek’s disease (MD) in chickens. The antiviral activity of vaccine-induced immunity against MD reduces the level of early cytolytic infection ...
