Oxidative Stress in Poultry: Lessons from the Viral Infections

Oxidative Medicine and Cellular Longevity, Volume 2018, Issue 1, 2018., 2018
Reactive species (RS), generally known as reactive oxygen species (ROS) and reactive nitrogen species (RNS), are produced during regular metabolism in the host and are required for many cellular processes such as cytokine transcription, immunomodulation, ion transport, and apoptosis.

Viral Bacterial Artificial Chromosomes: Generation, Mutagenesis, and Removal of Mini‐F Sequences

BioMed Research International, Volume 2012, Issue 1, 2012., 2012
Maintenance and manipulation of large DNA and RNA virus genomes had presented an obstacle for virological research. BAC vectors provided a solution to both problems as they can harbor large DNA sequences and can efficiently be modified using well‐established mutagenesis techniques in Escherichia coli.

Genome-wide host responses against infectious laryngotracheitis virus vaccine infection in chicken embryo lung cells

BMC Genomics, 2012
Background Infectious laryngotracheitis virus (ILTV; gallid herpesvirus 1) infection causes high mortality and huge economic losses in the poultry industry. To protect chickens against ILTV infection, chicken-embryo origin (CEO) and tissue-culture origin

Histopathological and genetic characterisation of Marek's disease in Sebright chickens from Brazil

Veterinary Record Case Reports, Volume 13, Issue 4, December 2025.
Abstract Marek's disease is a lymphoproliferative condition caused by Gallid alphaherpesvirus 2 (Marek's disease virus), affecting primarily birds of the order Galliformes. This study reports a case of Marek's disease in Sebright chickens in Rio de Janeiro, Brazil.

Multidecadal High Mortality Disease Events in Australian Domestic Geese Associated with a Novel Alphaherpesvirus, Designated Anatid Alphaherpevirus 2

Transboundary and Emerging Diseases, Volume 2024, Issue 1, 2024.
Herpesviruses are ubiquitous viruses which infect a wide range of hosts. Novel herpesviruses are being increasingly detected in free‐ranging bird populations and there are growing concerns for cross‐species infection and spillover events. Herein, multiple sporadic outbreaks of mortality caused by a herpesvirus are described in domestic geese in ...

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

Visceral Marek's disease in white-peafowl (Pavo cristatus)

Arquivo Brasileiro de Medicina Veterinária e Zootecnia
Marek's disease (MD) is a lymphoproliferative disorder caused by Gallid herpesvirus 2 (MDV) that infects mainly domestic gallinaceous birds although wild birds may occasionally be affected.

Genotypic characterization of two bacterial artificial chromosome clones derived from a single DNA source of the very virulent gallid herpesvirus-2 strain C12/130

Journal of General Virology, 2011
The identification of specific genetic changes associated with differences in the pathogenicity of Marek's disease virus strains (GaHV-2) has been a formidable task due to the large number of mutations in mixed-genotype populations within DNA preparations.

Accumulation of attenuating mutations in varying proportions within a high passage very virulent plus strain of Gallid herpesvirus type 2

Virus Research, 2010
Marek's disease (MD) is controlled through mass vaccination. Although these vaccines reduce or delay tumor formation they fail to induce sterilizing immunity and prevent virus shedding. Relatively little is known about the genetic changes that lead to attenuation.
