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

open access: yesJournal 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.

A Novel Approach to Mine for Genetic Markers via Comparing Class Frequency Distributions of Maximal Repeats Extracted from Tagged Whole Genomic Sequences [PDF]

open access: yes, 2018
The cost to extract one new biomarker within genomic sequences is very huge. This chapter adopts a scalable approach, developed previously and based on MapReduce programming model, to extract maximal repeats from a huge amount of tagged whole genomic ...

Viral forensic genomics reveals the relatedness of classic herpes simplex virus strains KOS, KOS63, and KOS79 [PDF]

open access: yes, 2016
Herpes simplex virus 1 (HSV-1) is a widespread global pathogen, of which the strain KOS is one of the most extensively studied. Previous sequence studies revealed that KOS does not cluster with other strains of North American geographic origin, but ...

Comparision of different cell cultures for replication of infectious laryngotracheitis virus from chickens [PDF]

open access: yes, 2018
The propagation of infectious laryngotracheitis virus (ILTV) has been described using primary cell cultures derived from chicken embryo liver and kidney or embryonated eggs, but these cultures use Specific Pathogen Free (SPF) eggs that are time and cost ...

Herpesviruses of birds [PDF]

open access: yes, 2011
In the order of Herpesvirales and the family of Herpesviridae, herpeviruses of birds, grouped in the subfamily of Alphaherpesvirinae, infect many avians, including chickens, turkeys, ducks, pigeons, parrots, eagles, storks, falcons ...

A phylogenomic analysis of Marek's disease virus reveals independent paths to virulence in Eurasia and North America [PDF]

open access: yes, 2017
Virulence determines the impact a pathogen has on the fitness of its host, yet current understanding of the evolutionary origins and causes of virulence of many pathogens is surprisingly incomplete. Here, we explore the evolution of Marek's disease virus

Multiple-Genome Annotation of Genome Fragments Using Hidden Markov Model Profiles [PDF]

open access: yes, 2008
To learn more about microbes and overcome the limitations of standard cultured methods, microbial communities are being studied in an uncultured state. In such metagenomic studies, genetic material is sampled from the environment and sequenced using the ...

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

open access: yesVirus 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.

Role of Virus-Encoded microRNAs in Avian Viral Diseases [PDF]

open access: yes, 2019
To survive in the host cells, viruses have to adapt various strategies, which include the modulation of microRNA (miRNA) pathway through virus-encoded miRNAs to modulate the host cellular environment.
