Ultrastructure, Morphology, and Sporogenesis of Pasteuria penetrans [PDF]
Phytopathology®, 1997 Pasteuria penetrans is a bacterial parasite of root-knot nematodes that shows great potential as a biocontrol agent. Scanning and transmission electron microscopy were used to study the ultrastructure, morphology, and sporogenesis of four isolates of P. penetrans. The effects of different Meloidogyne spp.

Modeling the Overdispersion of Pasteuria penetrans Endospores
Parasitologia, 2022 This paper discusses a process of developing the data analysis and modeling of Pasteuria penetrans spore attachment in vitro and in planta, based on the observation that the number of spores attaching to juveniles within a given time increased by increasing the time of exposure to spores and the spores dose. Based on this, the P.

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

BMC Genomics, 2018 Background Southern root-knot nematode Meloidogyne incognita (Kofoid and White, 1919), Chitwood, 1949 is a key pest of agricultural crops. Pasteuria penetrans is a hyperparasitic bacterium capable of suppressing the nematode reproduction, and represents ...

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 ...

The genetic basis of resistance and matching-allele interactions of a host-parasite system: The Daphnia magna-Pasteuria ramosa model. [PDF]
PLoS Genetics, 2017 Negative frequency-dependent selection (NFDS) is an evolutionary mechanism suggested to govern host-parasite coevolution and the maintenance of genetic diversity at host resistance loci, such as the vertebrate MHC and R-genes in plants.

Evidence for diversifying selection of genetic regions of encoding putative collagen-like host-adhesive fibers in Pasteuria penetrans [PDF]
, 2019 Pasteuria spp. belong to a group of genetically diverse endospore-forming bacteria (phylum: Firmicutes) that are known to parasitize plant-parasitic nematodes and water fleas (Daphnia spp.).

ENDOSYMBIONT MICROBIOTA OF Meloidogyne javanica ADULT FEMALE INFECTED BY Pasteuria penetrans
Tropical and Subtropical Agroecosystems, 2022 Background: Pasteuria penetrans is a nonculturable bacterium that obligately parasitizes several species of phytopathogenic nematodes. Unknown endogenous female, plant or microbial reproductive factors are indispensable for multiplication and endospore ...

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 ...
