Identification of a new antimicrobial lysine-rich cyclolipopeptide family from Xenorhabdus nematophila [PDF]

open access: yesThe Journal of Antibiotics, 2009
Entomopathogenic bacteria of the genus Xenorhabdus are known to be symbiotically associated with soil dwelling nematodes of the Steinernematidae family. These bacteria are transported by their nematode hosts into the hemocoel of the insect larvae, where they proliferate and produce insecticidal proteins, inhibitors of the insect immune system and ...

A novel secreted protein toxin from the insect pathogenic bacterium Xenorhabdus nematophila. [PDF]

open access: yesJournal of Biological Chemistry, 2004
The bacterium Xenorhabdus nematophila is an insect pathogen that produces several proteins that enable it to kill insects. Screening of a cosmid library constructed from X. nematophila strain A24 identified a gene that encoded a novel protein that was toxic to insects.

Comparative Genomics and Pathogenicity Analysis of Two Bacterial Symbionts of Entomopathogenic Nematodes: The Role of the GroEL Protein in Virulence

open access: yesMicroorganisms, 2022
Bacteria of the genera Xenorhabdus and Photorhabdus are symbionts of entomopathogenic nematodes. Despite their close phylogenetic relationship, they show differences in their pathogenicity and virulence mechanisms in target insects.

Clonal variation in Xenorhabdus nematophila virulence and suppression of Manduca sexta immunity [PDF]

open access: yesCellular Microbiology, 2007
Virulence of the insect pathogen Xenorhabdus nematophila is attributed in part to its ability to suppress immunity. For example, X. nematophila suppresses transcripts encoding several antimicrobial proteins, even in the presence of Salmonella enterica, an inducer of these transcripts. We show here that virulence and immune suppression phenotypes can be

Inhibition of Spodoptera frugiperda phenoloxidase activity by the products of the Xenorhabdus rhabduscin gene cluster.

open access: yesPLoS ONE, 2019
We evaluated the impact of bacterial rhabduscin synthesis on bacterial virulence and phenoloxidase inhibition in a Spodoptera model. We first showed that the rhabduscin cluster of the entomopathogenic bacterium Xenorhabdus nematophila was not necessary ...

Transcriptomic Analysis of Steinernema Nematodes Highlights Metabolic Costs Associated to Xenorhabdus Endosymbiont Association and Rearing Conditions

open access: yesFrontiers in Physiology, 2022
Entomopathogenic nematodes of the genus Steinernema have a mutualistic relationship with bacteria of the genus Xenorhabdus and together they form an antagonist partnership against their insect hosts. The nematodes (third-stage infective juveniles, or IJs)

<i>Xenorhabdus</i> and <i>Photorhabdus</i> Metabolites for Fungal Biocontrol and Application in Soybean Seed Protection. [PDF]

open access: yesJ Fungi (Basel)
Photorhabdus and Xenorhabdus bacteria, members of the Morganellaceae family, are sources of novel natural products for the biocontrol of fungal pathogens in soybean production.

Virulence and pathogen multiplication: a serial passage experiment in the hypervirulent bacterial insect-pathogen Xenorhabdus nematophila. [PDF]

open access: yesPLoS ONE, 2011
The trade-off hypothesis proposes that the evolution of pathogens' virulence is shaped by a link between virulence and contagiousness. This link is often assumed to come from the fact that pathogens are contagious only if they can reach high parasitic ...

Draft Genome Sequence and Annotation of the Entomopathogenic Bacterium Xenorhabdus nematophila Strain F1. [PDF]

open access: yesGenome Announc, 2013
ABSTRACT We report the 4.3-Mb genome sequence of Xenorhabdus nematophila strain F1, a Gram-negative bacterium that is a symbiont of the entomopathogenic nematode Steinernema carpocapsae and pathogenic by direct injection for a wide variety of insects.

Relative potency of a novel acaricidal compound from Xenorhabdus, a bacterial genus mutualistically associated with entomopathogenic nematodes

open access: yesScientific Reports, 2021
Our study aimed to identify the novel acaricidal compound in Xenorhabdus szentirmaii and X. nematophila using the easyPACId approach (easy Promoter Activated Compound Identification).
