A diverse parasite pool can improve effectiveness of biological control constrained by genotype‐by‐genotype interactions [PDF]
Evolutionary Applications, 2022 The outcomes of biological control programs can be highly variable, with natural enemies often failing to establish or spread in pest populations. This variability has posed a major obstacle in use of the bacterial parasite Pasteuria penetrans for ...

Do biological control agents adapt to local pest genotypes? A multiyear test across geographic scales [PDF]
Evolutionary ApplicationsParasite local adaptation has been a major focus of (co)evolutionary research on host–parasite interactions. Studies of wild host–parasite systems frequently find that parasites paired with local, sympatric host genotypes perform better than parasites ...

Transcriptomic Landscape Reveals Immunity Related Trade-Offs in an Invertebrate-Fungal Host-Parasite System. [PDF]
Mol EcolABSTRACT Host–parasite interactions represent an evolutionary arms race, with parasites evolving strategies to exploit host resources, and hosts deploying mechanisms to resist or tolerate infection. Unlike vertebrates, which possess a sophisticated immune system, invertebrates rely entirely on innate immunity to combat pathogens.

Successfully resisting a pathogen is rarely costly in
BMC Evolutionary Biology, 2010 Background A central hypothesis in the evolutionary ecology of parasitism is that trade-offs exist between resistance to parasites and other fitness components such as fecundity, growth, survival, and predator avoidance, or resistance to other parasites.

Phenotypic Adaptations in Pasteuria spp. Nematode Parasites.
Journal of nematology, 1995 The endospore and central core diameters of 69 isolates of Pasteuria spp. showed a relationship with the body wall thickness of their corresponding host nematodes. A relationship was also observed when cuticle and hypodermis layer data were derived from transmission electron microscopy micrographs.

Master of Puppets: How Microbiota Drive the Nematoda Ecology and Evolution? [PDF]
Ecol EvolThe nematode microbiota can influence life‐history traits, thereby shaping the species' ecology and evolutionary trajectories. ABSTRACT In recent decades, the microbiota has emerged as a key driver of biological functions in metazoans, and nematodes are no exception.

Integrating infection intensity and aggregation into the dynamics of pathogens with within-host replication. [PDF]
J Anim EcolWe bridge micro‐ and macroparasite theory with a model tracking pathogen load heterogeneity. By incorporating load‐dependent mortality and within‐host pathogen growth, we show how pathogen load aggregation alters disease prevalence, host suppression effects, and virulence evolution, providing insights for managing complex infectious disease like ...

Epidemiology of a Daphnia-multiparasite system and its implications for the red queen. [PDF]
PLoS ONE, 2012 The Red Queen hypothesis can explain the maintenance of host and parasite diversity. However, the Red Queen requires genetic specificity for infection risk (i.e., that infection depends on the exact combination of host and parasite genotypes) and ...

Emended description of Pasteuria nishizawae [PDF]
International Journal of Systematic and Evolutionary Microbiology, 2005 The description of the Gram-positive, obligately parasitic, mycelial and endospore-forming bacterium, Pasteuria nishizawae, is emended to include additional observations on the life cycle, host specificity and endospore morphology. The nucleotide sequence of the 16S rRNA gene is also provided.

Genetic and Immunological Comparison of the Cladoceran Parasite Pasteuria ramosa with the Nematode Parasite Pasteuria penetrans [PDF]
Applied and Environmental Microbiology, 2008 ABSTRACT Pasteuria penetrans , an obligate endospore-forming parasite of Meloidogyne spp. (root knot nematodes), has been identified as a promising agent for biocontrol of these destructive agricultural crop pests. Pasteuria ramosa , an obligate parasite of water fleas (
