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

, 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 ...

The central metabolism regulator EIIAGlc switches Salmonella from growth arrest to acute virulence through activation of virulence factor secretion [PDF]

, 2014
The ability of Salmonella to cause disease depends on metabolic activities and virulence factors. Here, we show that a key metabolic protein, EIIAGlc, is absolutely essential for acute infection, but not for Salmonella survival, in a mouse typhoid fever ...

Role of glucose and CcpA in capsule expression and virulence of Streptococcus suis [PDF]

, 2011
Streptococcus suis is one of the most important pathogens in pigs and is also an emerging zoonotic agent. After crossing the epithelial barrier, S. suis causes bacteraemia, resulting in meningitis, endocarditis and bronchopneumonia.

The coevolution of virulence : tolerance in perspective [PDF]

, 2010
Coevolutionary interactions, such as those between host and parasite, predator and prey, or plant and pollinator, evolve subject to the genes of both interactors.

Within-Host Dynamics of Multi-Species Infections:Facilitation, Competition and Virulence [PDF]

, 2012
Host individuals are often infected with more than one parasite species (parasites defined broadly, to include viruses and bacteria). Yet, research in infection biology is dominated by studies on single-parasite infections.

Novel cyclic di-GMP effectors of the YajQ protein family control bacterial virulence [PDF]

, 2014
Bis-(3',5') cyclic di-guanylate (cyclic di-GMP) is a key bacterial second messenger that is implicated in the regulation of many critical processes that include motility, biofilm formation and virulence. Cyclic di-GMP influences diverse functions through

Putative determinants of virulence in Melissococcus plutonius, the bacterial agent causing European foulbrood in honeybees [Elektronisk resurs] [PDF]

, 2020
Melissococcus plutonius is a bacterial pathogen that causes epidemic outbreaks of European foulbrood (EFB) in honey bee populations. The pathogenicity of a bacterium depends on its virulence, and understanding the mechanisms influencing virulence may ...

Predicting the virulence of MRSA from its genome sequence [PDF]

, 2014
This work is supported by the EC-FP7 program no. 245500 and the BBSRCMicrobial virulence is a complex and often multifactorial phenotype, intricately linked to a pathogen's evolutionary trajectory.
