First molecular detection and characterization of Marek’s disease virus in red-crowned cranes (Grus japonensis): a case report

BMC Veterinary Research, 2018
Background Marek’s disease virus (MDV) resides in the genus Mardivirus in the family Herpesviridae. MDV is a highly contagious virus that can cause neurological lesions, lymphocytic proliferation, immune suppression, and death in avian species, including

Construction and characterization of a H19 epitope point mutant of MDV CVI988/Rispens strain.

Acta virologica, 2000
A recombinant virus, CVI/rpp38, was developed from the Marek's disease virus (MDV) CVI988/Rispens vaccine strain. This recombinant was obtained by transfection of CVI988/Rispens-infected chick embryo fibroblasts (CEFs) with plasmid pHA25 DNA containing pp38 gene from GA strain of MDV. Monoclonal antibody (MAb) H19 which reacts with pp38 from GA but not

Effects of Gallid Herpesvirus 2 Marek's Disease Challenge Virus and Attenuated Vaccine Virus CVI988/Rispens on Immune Adhesion of Erythrocytes of Chickens

International Journal of Poultry Science, 2013
This study was designed to investigate the influence of Gallid herpesvirus 2 Marek's Disease challenge virus and different inoculated routes of attenuated vaccine virus CVI988/Rispens on immun e adhesion of erythrocytes in chickens. One day old chicks were randomly divided into a control group (C), an experimental group challenged with Jing-1 challenge

Transcriptional and Bioinformatic Analysis Provide a Relationship between Host Response Changes to Marek’s Disease Viruses Infection and an Integrated Long Terminal Repeat

Frontiers in Cellular and Infection Microbiology, 2016
GX0101, Marek’s disease virus (MDV) strain with a long terminal repeat (LTR) insert of reticuloendotheliosis virus (REV), was isolated from CVI988/Rispens vaccinated birds showing tumors.

Trials for isolation and identification of Marek's disease virus (MDV) in layer chicken farms vaccinated with MDV vaccines exhibiting MDV-like symptoms in Egypt [PDF]

Benha Veterinary Medical Journal
Marek's disease virus (MDV) is a lymphoproliferative neuropathic disease affecting domestic fowl. Despite intensive vaccination, Egyptian poultry farms continue to experience recurrent infections of MDV.

Retos en el diagnóstico y control del virus de la enfermedad de Marek en Colombia [PDF]

, 2019
Aunque la industria avícola colombiana ha crecido casi el doble en producción durante la última década, el diagnóstico de agentes infecciosos y caracterización de estos aún es escasa, y es poca la información acerca de las cepas virales circulantes en el

High-fidelity long-read sequencing of an avian herpesvirus reveals extensive intrapopulation diversity in tandem repeat regions.

PLoS Pathogens
Comparative genomic studies of Marek's disease virus (MDV) have suggested that attenuated and virulent strains share >98% sequence identity. However, these estimates fail to account for variation in regions of the MDV genome harboring tandem repeats.

Deletion of the meq gene significantly decreases immunosuppression in chickens caused by pathogenic marek's disease virus

Virology Journal, 2011
Background Marek's disease virus (MDV) causes an acute lymphoproliferative disease in chickens, resulting in immunosuppression, which is considered to be an integral aspect of the pathogenesis of Marek's disease (MD).

Characterization of immunopathological changes in the feather pulp of CVI988-vaccinated pullets challenged with a very virulent plus Marek’s disease virus strain

Avian Pathology
High load of oncogenic Marek’s disease virus (MDV) DNA in the feather pulp (FP) as early as 21 days of age is a powerful criterion to predict the outcome of Marek’s disease (MD) in apparently healthy chickens. The objective of this study was to elucidate the immunopathological changes in the FP of 21-days-old chickens that had been vaccinated with ...
