Comparative genomics of the emerging human pathogen Photorhabdus asymbiotica with the insect pathogen Photorhabdus luminescens

BMC Genomics, 2009
Background The Gram-negative bacterium Photorhabdus asymbiotica (Pa) has been recovered from human infections in both North America and Australia. Recently, Pa has been shown to have a nematode vector that can also infect insects, like its sister species

The FsrA‐Mediated Iron‐Sparing Response Regulates the Biosynthesis of the Epipeptide EPE in Bacillus subtilis

Molecular Microbiology, Volume 125, Issue 2, Page 108-122, February 2026.
Under iron‐limited conditions, FsrA base‐pairs with the intergenic region between epeX and epeE, enhancing epeE translation and triggering EPE production. Toxin‐mediated cell lysis releases nutrients, including iron, which can be taken up by surviving cells.

Structural studies on oxalate decarboxylase from Photorhabdus luminescens [PDF]

Acta Crystallographica Section A Foundations and Advances, 2014
As a part of exploration of novel bacterial genes coding for insecticidal proteins, we have initiated structural and functional studies on oxalate decarboxylase from Photorhabdus luminescens, a symbiotic bacteria inhabiting guts of nematodes that parasitize insects.

A novel tool for stable genomic reporter gene integration to analyze heterogeneity in Photorhabdus luminescens at the single-cell level

BioTechniques, 2015
Determination of reporter gene activity at the single-cell level is a prerequisite for analyzing heterogeneous gene expression in bacteria. The insect pathogenic enteric bacterium Photorhabdus luminescens is an excellent organism in which to study ...

A bacterial binary toxin system that kills both insects and aquatic crustaceans: Photorhabdus insect-related toxins A and B.

PLoS Pathogens, 2023
Photorhabdus insect-related toxins A and B (PirA and PirB) were first recognized as insecticidal toxins from Photorhabdus luminescens. However, subsequent studies showed that their homologs from Vibrio parahaemolyticus also play critical roles in the ...

A Modular Biosensor Platform for the Detection of Plastic Monomers and the Engineering of Promiscuous Amidases Toward Challenging Substrates

Advanced Science, Volume 13, Issue 6, 30 January 2026.
A luciferase is used as biosensor for aldehydes, produced enzymatically from different monomeric building blocks of plastics like polyurethanes (PUs). The screening platform is used to monitor esterase, amidase, and urethanase activity and to guide the selection of enzyme variants with improved hydrolytic activities toward difficult to hydrolyze ...

The Type VI secretion systems of the insect pathogen Photorhabdus luminescens are involved in interbacterial competition, motility and secondary metabolism

The Microbe
The Type VI Secretion System (T6SS) is used as weapon by a variety of Gram-negative bacteria in polymicrobial niche competition. Its characterization and study gained more interest in recent years.

Comparative analysis of the Photorhabdus luminescens and the Yersinia enterocolitica genomes: uncovering candidate genes involved in insect pathogenicity

BMC Genomics, 2008
Background Photorhabdus luminescens and Yersinia enterocolitica are both enteric bacteria which are associated with insects. P. luminescens lives in symbiosis with soil nematodes and is highly pathogenic towards insects but not to humans. In contrast, Y.

Influence of Osmolarity on Phase Shift in Photorhabdus luminescens [PDF]

Applied and Environmental Microbiology, 1995
The influence of osmolarity and other environmental factors like low oxygen levels, light, extreme pH values, and temperatures on phase variation of Photorhabdus luminescens, the symbiotic bacterium of entomopathogenic nematodes of the genus Heterorhabditis, was investigated.
