Is HIV short-sighted? Insights from a multistrain nested model [PDF]

open access: yes, 2013
An important component of pathogen evolution at the population level is evolution within hosts. Unless evolution within hosts is very slow compared to the duration of infection, the composition of pathogen genotypes within a host is likely to change ...

Re-Assembly and Analysis of an Ancient Variola Virus Genome

open access: yesViruses, 2017
We report a major improvement to the assembly of published short read sequencing data from an ancient variola virus (VARV) genome by the removal of contig-capping sequencing tags and manual searches for gap-spanning reads. The new assembly, together with

M148R and M149R are two virulence factors for myxoma virus pathogenesis in the European rabbit [PDF]

open access: yes, 2009
Myxoma virus (MYXV), a member of the Poxviridae family, is the agent responsible for myxomatosis, a fatal disease in the European rabbit (Oryctolagus cuniculus).

A new inhibitor of apoptosis from vaccinia virus and eukaryotes. [PDF]

open access: yes, 2007
A new apoptosis inhibitor is described from vaccinia virus, camelpox virus, and eukaryotic cells. The inhibitor is a hydrophobic, multiple transmembrane protein that is resident in the Golgi and is named GAAP (Golgi anti-apoptotic protein).

The relationship of within-host multiplication and virulence in a plant-virus system. [PDF]

open access: yesPLoS ONE, 2007
Virulence does not represent any obvious advantage to parasites. Most models of virulence evolution assume that virulence is an unavoidable consequence of within-host multiplication of parasites, resulting in trade-offs between within-host multiplication

Parasite variation and the evolution of virulence in a Daphnia-microparasite system [PDF]

open access: yes, 2008
Understanding genetic relationships amongst the life-history traits of parasites is crucial for testing hypotheses on the evolution of virulence. This study therefore examined variation between parasite isolates (the bacterium Pasteuria ramosa) from the ...

Molecular basis for a lack of correlation between viral fitness and cell killing capacity. [PDF]

open access: yesPLoS Pathogens, 2007
The relationship between parasite fitness and virulence has been the object of experimental and theoretical studies often with conflicting conclusions. Here, we provide direct experimental evidence that viral fitness and virulence, both measured in the ...

MNF, an ankyrin repeat protein of myxoma virus, is part of a native cellular SCF complex during viral infection [PDF]

open access: yes, 2010
Myxoma virus (MYXV), a member of the Poxviridae family, is the agent responsible for myxomatosis, a fatal disease in the European rabbit (Oryctolagus cuniculus).

Virulence of H5N1 virus in mice attenuates after in vitro serial passages

open access: yesVirology Journal, 2011
The virulence of A/Vietnam/1194/2004 (VN1194) in mice attenuated after serial passages in MDCK cells and chicken embryos, because the enriched large-plaque variants of the virus had significantly reduced virulence.

Rift Valley fever virus 78kDa envelope protein attenuates virus replication in macrophage-derived cell lines and viral virulence in mice.

open access: yesPLoS Neglected Tropical Diseases, 2021
Rift Valley fever virus (RVFV) is a mosquito-borne bunyavirus with a wide host range including ruminants and humans. RVFV outbreaks have had devastating effects on public health and the livestock industry in African countries.
