Variations in the H/ACA box sequence of viral telomerase RNA of isolates of CVI988 Rispens vaccine

open access: yesArchives of Virology, 2008
The use of the complete DNA sequence for the Marek's disease virus (MDV) serotype 1 vaccine strain CVI988 Rispens in comparative genomic studies with virulent strains of MDV has revealed the presence of a number of insertions, deletions and single-nucleotide polymorphisms.

Effects of Rispens CVI988 vaccination followed by challenge with Marek’s disease viruses of differing virulence on the replication kinetics and shedding of the vaccine and challenge viruses

open access: yesVeterinary Microbiology, 2016
Vaccination with "imperfect" vaccines that prevent disease but not infection is strongly implicated in the observed increased virulence of Marek's disease virus (MDV) over the past six decades. The current "gold standard" vaccine, Rispens CVI988 (Rispens), has maintained efficacy despite use for five decades, raising the question of whether it too ...

Differentiation between pathogenic serotype 1 isolates of Marek's disease virus and the Rispens CVI988 vaccine in Australia using real-time PCR and high resolution melt curve analysis

open access: yesJournal of Virological Methods, 2013
Two real-time PCR assays were developed which enable quantitation and differentiation between pathogenic Australian isolates of Marek's disease virus (MDV) serotype 1 and the serotype 1 vaccine strain Rispens CVI988. The assays are based on a DNA sequence variation in the meq gene between pathogenic and vaccinal MDV1 which has been confirmed by ...

In vitro characterization of the Meq proteins of Marek's disease virus vaccine strain CVI988

Virus Research, 2009
Gallid herpesvirus 2 (GaHV-2), commonly known as Marek's disease virus serotype-1 (MDV-1), causes T cell lymphomas in chickens. Vaccines prepared from the attenuated CVI988/Rispens MDV-1 strain currently offer the best protection. Although attenuated CVI988/Rispens is non-oncogenic, it codes for at least two forms of the MDV oncoprotein Meq, and these ...
