Bacteriocins, spite and virulence.
There has been much interest in using social evolution theory to predict the damage to a host from parasite infection, termed parasite virulence. Most of this work has focused on how high kinship between the parasites infecting a host can select for more prudent exploitation of the host, leading to a negative relationship between virulence and parasite kinship. However, it has also been shown t...
متن کاملSpite and virulence in the bacterium Pseudomonas aeruginosa.
Social interactions within populations of pathogenic microbes may play an important role in determining disease virulence. One such ubiquitous interaction is the production of anticompetitor toxins; an example of a spiteful behavior, because it results in direct fitness costs to both the actor and recipient. Following from predictions made by mathematical models, we carried out experiments usin...

" At least £10 million is needed every year to protect and restore the rich biodiversity of these remote islands, " says Graham Wynne, chief executive of the RSPB...
متن کاملA peptide factor secreted by Staphylococcus pseudintermedius exhibits properties of both bacteriocins and virulence factors
Staphylococcus pseudintermedius is a common commensal bacterium colonizing the skin and mucosal surfaces of household animals. However, it has recently emerged as a dangerous opportunistic pathogen, comparable to S. aureus for humans. The epidemiological situation is further complicated by the increasing number of methicillin-resistant S. pseudintermedius infections and evidence of gene transmi...
