Beware glowing cadavers: bioluminescence of nematode symbiont Photorhabdus protects nematode-infected host cadavers from nocturnal scavengers

Frontiers in Ecology and Evolution
Photorhabdus spp. are the only known terrestrial bioluminescent bacteria. We show that the bioluminescence produced by these bacteria reduces scavenging activity on the insect cadavers they colonize. Photorhabdus spp.

A systematic review on research trends and commercialised entomopathogenic nematodes: A global perspective

Agricultural and Forest Entomology, EarlyView.
Out of 136 identified EPNs, only 18 (8 Steinernema and 6 Heterorhabditis) are commercialised globally, highlighting a major gap between discovery and application. High production costs and inconsistent field efficacy are the leading obstacles to the widespread commercialisation of EPN‐based biocontrol products.

LuxS-dependent AI-2 production is not involved in global regulation of natural product biosynthesis in Photorhabdus and Xenorhabdus [PDF]

PeerJ, 2017
The Gram-negative bacteria Photorhabdus and Xenorhabdus are known to produce a variety of different natural products (NP). These compounds play different roles since the bacteria live in symbiosis with nematodes and are pathogenic to insect larvae in the

How effective are entomopathogenic nematodes for vine weevil (Coleoptera: Curculionidae) biological control? A meta‐analysis

Pest Management Science, Volume 82, Issue 4, Page 3427-3438, April 2026.
Entomopathogenic nematodes provide reliable biological control of vine weevil larvae, reducing populations by 63% on average. All five tested species are effective, with temperature (18–30 °C) being the strongest predictor of success. Abstract BACKGROUND Vine weevil (Otiorhynchus sulcatus) is a globally important pest of soft fruit and ornamental crops

Isolation and identification of Xenorhabdus and Photorhabdus bacteria associated with entomopathogenic nematodes and their larvicidal activity against Aedes aegypti

Parasites & Vectors, 2017
Background Aedes aegypti is a potential vector of West Nile, Japanese encephalitis, chikungunya, dengue and Zika viruses. Alternative control measurements of the vector are needed to overcome the problems of environmental contamination and chemical ...

Two Philippine Photorhabdus luminescens strains inhibit the in vitro growth of Lasiodiplodia theobromae, Fusarium oxysporum f. sp. lycopersici, and Colletotrichum spp.

Egyptian Journal of Biological Pest Control, 2021
Background Fungal phytopathogens are one of the leading causes of loss in global food production. Chemical fungicides have always been used to control the phytopathogens to mitigate losses.

Photorhabdus sp. ETL Antimicrobial Properties and Characterization of Its Secondary Metabolites by Gas Chromatography–Mass Spectrometry

Life, 2021
Entomopathogenic nematodes (EPNs) are known to be highly pathogenic to insect pests, due to their associated symbiotic bacteria, which produce virulence factors, exo-enzymes and other harmful secondary metabolites to conquer, kill, and degrade their ...

Synthetic Studies Towards Darobactin A

Chemistry – A European Journal, Volume 32, Issue 10, 9 March 2026.
The urgent need for new antibiotics led us to develop a new methodology for the synthesis of the natural product darobactin A selectively targeting gram‐negative bacteria. This study provides new insights into the synthesis of strained indole‐containing macrocycles.

Molecular basis of antibiotic sensing by the TetR family regulator CecR – a structural perspective

The FEBS Journal, Volume 293, Issue 6, Page 1801-1817, March 2026.
Escherichia coli CecR, a member of the TetR family regulators, senses selected antibiotics and activates the expression of a putative drug efflux pump. Although present in many pathogenic Enterobacteriales strains, CecR remains poorly characterized. We present the first CecR crystal structure, which reveals a unique tunnel‐like ligand‐binding cavity ...
