Characterization of the putative antigenic determinants on Pasteuria endospore surface using Bacillus thuringiensis as a comparative tool

, 2016
Biological control agents are emerging as potential environmentally benign means of combating phytonematodes across the world. Some species of Pasteuria are endospore forming bacterial hyperparasites of nematodes associated with nematode suppressive ...

TNF Production or TNFR2 Expression Characterize Distinct States of Regulatory T Cells that Cooperate in Treg Expansion in Cancer and Chronic Inflammation

European Journal of Immunology, Volume 55, Issue 9, September 2025.
Tregs exist in two functional states: TNF‐producing Tregs, which are expanded in mouse models of chronic inflammation and cancer, and TNFR2‐expressing Tregs, which dominate and transmit their phenotype to TNF+ Tregs. The two states are characterized by distinct phenotypic and functional features. Created in BioRender. Piconese, S.

Kajian Bioekologi Pasteuria penetrans

Jurnal Perlindungan Tanaman Indonesia, 1996
In bioecological studies of P. penetrans, six experiments were done i.e. study the nematode hosts of P. penetrans; the effect of temperature, soil moisture, spores storage length, soil chemicals (compound  fertilizer, carbofuran, and mancozeb) and methods of application on the pathogenicity of P. penetrans.

Unveiling the Host-range Distribution of Pasteuria penetrans Against Various Root-knot Nematode, Meloidogyne spp [PDF]

Madras Agricultural Journal
Root-knot nematodes (Meloidogyne spp.) are economically significantplant parasites causing extensive damage to various crops globally. Theirsedentary endoparasitic nature, facilitated by a stylet, induces the formationof giant cells in plant roots ...

Pre‐Crop Choice Shapes Nematode‐Attached Bacterial Communities Associated With Reduced Pratylenchus penetrans Invasion of Barley Roots

Environmental Microbiology, Volume 27, Issue 9, September 2025.
Plant species vary in how they shape nematode‐suppressive soil microbiomes, and these legacies influence the subsequent crop. Suppressive microbiomes contain specific bacterial taxa that attach to the nematode cuticle, leading to reduced nematode invasion into the root system of the host.

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 ...

Functional Genomics of Pasteuria penetrans, An Obligate Hyperparasite of Root-knot Nematodes, Meloidogyne spp.

, 2007
The Gram-positive, endospore-forming bacterium Pasteuria penetrans is an obligate parasite of root-knot nematodes, Meloidogyne spp., which themselves are parasites of plants. Pasteuria penetrans has a demonstrated ability to control root-knot nematodes,

Pasteuria penetrans and P. nishizawae attachment to Meloidogyne chitwoodii, M. fallax and M. hapla [PDF]

, 2004
This is the first report of endospores of Pasteuria penetrans and P. nishizawae isolates binding to juveniles of Meloidogyne chitwoodi and M. fallax. The patterns of endospore attachment to M. chitwoodi and M. fallax compared with the related M.

Pasteuria sp. Parasitizing Trophonema okamotoi in Florida.

Journal of nematology, 2011
Two populations of Trophonema okamotoi parasitized by Pasteuria sp. were found on Liquidambar styraciflua (sweetgum) and on an unidentified tropical grass in north-central Florida. Endospores of this Pasteuria sp. attached to motile vermiform second-stage juveniles (J2) and males of T. okamotoi, but not to other developmental stages.

Identification of new single nucleotide polymorphism-based markers for inter- and intraspecies discrimination of obligate bacterial parasites (Pasteuria spp.) of invertebrates

, 2011
Protein-encoding and 16S rRNA genes of Pasteuria penetrans populations from a wide range of geographic locations were examined.
