Virulence related sequences: insights provided by comparative genomics of Streptococcus uberis of differing virulence
Published 2015“…This first “whole-genome” comparison of strains isolated from clinical vs non-clinical intramammary infections including the type virulent vs non-virulent strains did not identify simple gene gain/loss rules that readily explain, or be confidently associated with, differences in virulence. …”

Proteinaceous necrotrophic effectors in fungal virulence
Published 2010“…Such effectors are only found in necrotrophic fungi, yet their roles in virulence are poorly understood. However, several recent key studies of necrotrophic effectors from two wheat (Triticum aestivum L.) pathogens, Pyrenophora tritici-repentis (Died.) …”

Evolutionary ecology of virulence in a fish parasite
Published 2016“…Virulence (parasite- induced host fitness reduction) is thought to correlate positively with pathogen reproduction rates, but its relationship with pathogen transmission is likely to be determined by a trade- off between the costs and benefits of harming hosts. …”

Transcription factor control of virulence in phytopathogenic fungi
Published 2021“…Novel protection strategies are required and therefore it is critical we understand the mechanisms by which these pathogens cause disease. Virulence factors and pathogenicity genes have been identified, but in many cases their roles remain elusive. …”

Cooperation, quorum sensing, and evolution of virulence in Staphylococcus aureus
Published 2014“…The virulence and fitness in vivo of the major human pathogen Staphylococcus aureus are associated with a cell-to-cell signaling mechanism known as quorum sensing (QS). …”

Kin selection, quorum sensing and virulence in pathogenic bacteria
Published 2012“…Bacterial growth and virulence often depends upon the cooperative release of extracellular factors excreted in response to quorum sensing (QS).We carried out an in vivo selection experiment in mice to examine how QS evolves in response to variation in relatedness (strain diversity), and the consequences for virulence. …”

Virulence determinants of Lactococcus garvieae, an important pathogen of trout
Published 2018“…Various bioinformatic platforms were employed to further categorise these by functional group and to identify genes with potential involvement in virulence which could form useful vaccination candidates, diagnostic markers or therapeutic targets. …”

Impact of genetic changes in the Enterovirus 71 genome on virulence
Published 2019“…Currently, it is unknown if the virulence of EV-A71 is contributed by the events of recombination between EV-A71 and other enteroviruses or it is due to the presence of spontaneous mutations that affect its virulence.…”
