Evolution of Rabies Virus Isolates: Virulence Signatures and Effects of Modulation by Neutralizing Antibodies

open access: yesPathogens, 2022
Lyssavirus rabies (RABV) is an RNA virus and, therefore, is subject to mutations due to low RNA polymerase replication fidelity, forming a population structure known as a viral quasispecies, which is the core of RNA viruses’ adaptive strategy.

The pepper virome: natural co-infection of diverse viruses and their quasispecies

open access: yesBMC Genomics, 2017
Background The co-infection of diverse viruses in a host plant is common; however, little is known about viral populations and their quasispecies in the host.

Quasispecies and recombination

open access: yesTheoretical Population Biology, 2006
Recombination is introduced into Eigen's theory of quasispecies evolution. Comparing numerical simulations of the rate equations in the non-recombining and recombining cases show that recombination has a strong effect on the error threshold and, for a wide range of mutation rates, gives rise to two stable fixed points in the dynamics. This bi-stability

Quasispecies Structure and Persistence of RNA Viruses

open access: yesEmerging Infectious Diseases, 1998
Viral quasispecies are closely related (but nonidentical) mutant and recombinant viral genomes subjected to continuous genetic variation, competition, and selection.

Composition and Dynamics of H1N1 and H7N9 Influenza A Virus Quasispecies in a Co-infected Patient Analyzed by Single Molecule Sequencing Technology

open access: yesFrontiers in Genetics, 2021
A human co-infected with H1N1 and H7N9 subtypes influenza A virus (IAV) causes a complex infectious disease. The identification of molecular-level variations in composition and dynamics of IAV quasispecies will help to understand the pathogenesis and ...

Semiconservative Replication in the Quasispecies Model [PDF]

open access: yes, 2003
This paper extends Eigen's quasispecies equations to account for the semiconservative nature of DNA replication. We solve the equations in the limit of infinite sequence length for the simplest case of a static, sharply peaked fitness landscape.

PAQ: Partition Analysis of Quasispecies [PDF]

open access: yesBioinformatics, 2001
Abstract Motivation: The complexities of genetic data may not be accurately described by any single analytical tool. Phylogenetic analysis is often used to study the genetic relationship among different sequences. Evolutionary models and assumptions are invoked to reconstruct trees that describe the phylogenetic relationship among ...

Viral quasispecies quantitative analysis: a novel approach for appraising the immune tolerant phase of chronic hepatitis B virus infection

open access: yesEmerging Microbes and Infections, 2021
Few non-invasive models were established for precisely identifying the immune tolerant (IT) phase from chronic hepatitis B (CHB). This study aimed to develop a novel approach that combined next-generation sequencing (NGS) and machine learning algorithms ...

RNA three-dimensional structure drives the sequence organization of potato spindle tuber viroid quasispecies.

open access: yesPLoS Pathogens
RNA viruses and viroids exist and evolve as quasispecies due to error-prone replication. Quasispecies consist of a few dominant master sequences alongside numerous variants that contribute to genetic diversity.
