Toxins and Secretion Systems of Photorhabdus luminescens

Toxins, 2010
Photorhabdus luminescens is a nematode-symbiotic, gram negative, bioluminescent bacterium, belonging to the family of Enterobacteriaceae.Recent studies show the importance of this bacterium as an alternative source of insecticides, as well as an emerging

Nematicidal effects of Photorhabdus- and Xenorhabdus-derived compounds against plant-parasitic nematodes: a systematic review and meta-analysis [PDF]

Frontiers in Plant Science
Plant-parasitic nematodes (PPNs) are major agricultural pests that cause substantial yield losses worldwide. However, developing sustainable alternatives to synthetic nematicides remains a critical challenge.

Genetic architecture of resistance to plant secondary metabolites in Photorhabdus entomopathogenic bacteria [PDF]

BMC Genomics
Background Entomopathogenic nematodes of the genus Heterorhabditis establish a symbiotic association with Photorhabdus bacteria. Together, they colonize and rapidly kill insects, making them important biological control agents against agricultural pests.

A novel homoarginine-containing cyclic peptide pioamide with selective antipseudomonal activity isolated from the nematode symbiont Photorhabdus khanii [PDF]

Applied and Environmental Microbiology
Gram-negative bacteria harbor an outer membrane that physically protects them from the penetration of antibiotics into the cells. This barrier makes it challenging to develop antibiotics that effectively kill Gram-negative pathogens. The entomopathogenic

Molluscicidal property of symbiotic bacteria associated with entomopathogenic nematodes against Indoplanorbis exustus and Radix rubiginosa, the intermediate hosts of trematode parasites [PDF]

Parasite Epidemiology and Control
Indoplanorbis exustus and Radix rubiginosa act as intermediate hosts for veterinary and medical trematode parasites. Snail control is a strategy used to decrease the number of snails and interrupt the life cycle of parasites.

Injection of Affibodies by a Self-Organizing Bacterial Syringe to Interfere with Intracellular Signaling [PDF]

Toxins
Photorhabdus luminescens produces a syringe-like toxin complex to inject toxic enzymes into cells. We demonstrated that the recombinant Photorhabdus toxin complex (PTC) can be engineered for translocation of foreign cargo proteins across cellular ...

Molecular Characterization and Antibacterial Activities of Photorhabdus and Xenorhabdus from Mizoram, North-East India

Journal of Pure and Applied Microbiology, 2023
Photorhabdus and Xenorhabdus are the bacterial symbionts of insect pathogenic nematodes, Heterorhabditis and Steinernema, respectively. This study aims to characterize the bacterial symbionts from Mizoram, North-east India and to evaluate their ...
