Host-Parasite Co-evolution and Optimal Mutation Rates for Semi-conservative Quasispecies
, 2004 In this paper, we extend a model of host-parasite co-evolution to incorporate the semi-conservative nature of DNA replication for both the host and the parasite.

Modeling HIV quasispecies evolutionary dynamics [PDF]
BMC Evolutionary Biology, 2007 Abstract Background During the HIV infection several quasispecies of the virus arise, which are able to use different coreceptors, in particular the CCR5 and CXCR4 coreceptors (R5 and X4 phenotypes, respectively). The switch in coreceptor usage has been correlated with a faster progression of the disease to the AIDS ...

Dynamical Analysis of an HIV Infection Model Including Quiescent Cells and Immune Response
Mathematical Methods in the Applied Sciences, Volume 48, Issue 15, Page 14301-14315, October 2025.ABSTRACT This research gives a thorough examination of a human immunodeficiency virus (HIV) infection model that includes quiescent cells and immune response dynamics in the host. The model, represented by a system of ordinary differential equations, captures the complex interaction between the host's immune response and viral infection.

, 2011 Several pathogens use evolvability as a survival strategy against acquired immunity of the host. Despite their high variability in time, some of them exhibit quite low variability within the population at any given time, a somehow paradoxical behavior ...

Discovering Complete Quasispecies in Bacterial Genomes [PDF]
Genetics, 2017 Abstract Mobile genetic elements can be found in almost all genomes. Possibly the most common nonautonomous mobile genetic elements in bacteria are repetitive extragenic palindromic doublets forming hairpins (REPINs) that can occur hundreds of times within a genome.

Journal of Medical Virology, Volume 97, Issue 8, August 2025.ABSTRACT Due to the continuous genetic evolution of SARS‐CoV‐2, numerous variants have emerged and different whole genome sequencing techniques, necessary for accurate virus typing, have been developed. In this study, we evaluated the performance of PacBio single‐molecule real‐time (SMRT) sequencing for SARS‐CoV‐2 typing.

Evolutionary Applications, Volume 18, Issue 8, August 2025.ABSTRACT RNA viruses often comprise multiple variants that co‐circulate in a host population, with potentially complex dynamics. Deformed wing virus (DWV), arguably the most impactful virus of honey bees (Apis mellifera), nowadays exists as two major variants, genotypes A (DWV‐A) and B (DWV‐B), which provide an amenable window into the dynamics of ...
