Stability of entomopathogenic bacteria, Xenorhabdus nematophila and Photorhabdus luminescens, during in vitro culture

Journal of Industrial Microbiology & Biotechnology, 2006
The entomopathogenic nematode-bacteria complexes Heterorhabditis bacteriophora/Photorhabdus luminescens and Steinernema carpocapsae/Xenorhabdus nematophila are mass produced for use as biological insecticides. Stability of the bacterial partner in culture is essential for maintaining traits important for both biological control and production.

An encoded N-terminal extension results in low levels of heterologous protein production in Escherichia coli

Microbial Cell Factories, 2005
Background The tdk gene (encoding deoxythymidine kinase) of the gamma-proteobacterium Xenorhabdus nematophila has two potential translation start sites. The promoter-distal start site was predicted to be functional based on amino acid sequence alignment ...

The bacterium Xenorhabdus nematophila inhibits phospholipases A2 from insect, prokaryote, and vertebrate sources

Naturwissenschaften, 2004
The bacterium, Xenorhabdus nematophila, is a virulent insect pathogen. Part of its pathogenicity is due to impairing cellular immunity by blocking biosynthesis of eicosanoids, the major recognized signal transduction system in insect cellular immunity. X. nematophila inhibits the first step in eicosanoid biosynthesis, phospholipase A(2) (PLA(2)).

Membrane insertion of α-xenorhabdolysin in near-atomic detail

eLife, 2018
α-Xenorhabdolysins (Xax) are α-pore-forming toxins (α-PFT) that form 1–1.3 MDa large pore complexes to perforate the host cell membrane. PFTs are used by a variety of bacterial pathogens to attack host cells.

Studying of the regulatory roles of response regulators GlrR and ArcA in xenocoumacins biosynthesis in Xenorhabdus nematophila CB6

Journal of Integrative Agriculture
Xenocoumacins (Xcns), the major antimicrobial natural products produced by Xenorhabdus nematophila, have gained widespread attention for their potential application in crop protection.

Optical mapping as a routine tool for bacterial genome sequence finishing

BMC Genomics, 2007
Background In sequencing the genomes of two Xenorhabdus species, we encountered a large number of sequence repeats and assembly anomalies that stalled finishing efforts.

Expression, Purification, and Functional Analysis of Novel RelE Operon from X. nematophila

The Scientific World Journal, 2014
Bacterial toxin-antitoxin (TA) complexes induce programmed cell death and also function to relieve cell from stress by various response mechanisms. Escherichia coli RelB-RelE TA complex consists of a RelE toxin functionally counteracted by RelB antitoxin.

Heterogeneity within infections: the case of the vector-borne insect pathogen, Xenorhabdus nematophila

, 2018
Numerous studies have considered infections as pairwise interactions between a single pathogen and its host, sometimes leading to an incomplete picture of infectious processes. In this work, we focused on more complex types of interactions that arise because infections are usually heterogeneous. More precisely, we have investigated two main issues: (I)
