Host specificity and genetics of host resistance in the "Daphnia-Pasteuria" host-parasite system [PDF]
, 2012 Antagonistic coevolution plays an important role in a large number of evolutionary and ecological phenomena. Furthermore, according to the Red Queen Theory coevolution between hosts and their parasites may explain the maintenance of sexual reproduction ...

Evolutionary and proximate mechanisms shaping host-parasite interactions : the case of "Daphnia magna" and its natural bacterial parasite "Pasteuria ramosa" [PDF]
, 2011 Host-parasite interactions are composed of a sequence of steps, all necessary for successful infection: parasites need to encounter their hosts, to enter into their bodies, and to proliferate within them. Selection will act on the mechanisms used in each

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 ...

Responses of a bacterial pathogen to phosphorus limitation of its aquatic invertebrate host [PDF]
, 2008 Host nutrition is thought to affect the establishment, persistence, and severity of pathogenic infections. Nutrient-deficient foods possibly benefit pathogens by constraining host immune function or benefit hosts by limiting parasite growth and ...

Dietary supply with polyunsaturated fatty acids and resulting maternal effects influence host -- parasite interactions [PDF]
, 2013 Interactions between hosts and parasites can be substantially modulated by host nutrition. Polyunsaturated fatty acids (PUFAs) are essential dietary nutrients; they are indispensable as structural components of cell membranes and as precursors for ...

Maternal Stress Reduces the Susceptibility of Root-Knot Nematodes to Pasteuria Penetrans
Journal of Nematology, 2019 Pasteuria penetrans is an obligate parasite of root-knot nematodes (Meloidogyne spp.). Endospores of P. penetrans attach to the cuticle of second-stage juveniles (J2) and complete their life cycle within the nematode female body. Infected females will be

Assessment of parasite virulence in a natural population of a planktonic crustacean
BMC Ecology, 2019 Background Understanding the impact of disease in natural populations requires an understanding of infection risk and the damage that parasites cause to their hosts (= virulence).

Sex-specific effects of a parasite evolving in a female-biased host population
BMC Biology, 2012 Background Males and females differ in many ways and might present different opportunities and challenges to their parasites. In the same way that parasites adapt to the most common host type, they may adapt to the characteristics of the host sex they ...

PLoS ONE, 2014 Host density can increase infection rates and reduce host fitness as increasing population density enhances the risk of becoming infected either through increased encounter rate or because host condition may decline.

Evolution Letters, 2019 Repeated extinction and recolonization events generate a landscape of host populations that vary in their time since colonization. Within this dynamic landscape, pathogens that excel at invading recently colonized host populations are not necessarily ...
