 Photorhabdus luminescens

Photorhabdus luminescens (previously called "Xenorhabdus luminescens") is a Gammaproteobacterium of the family Morganellaceae, and is a lethal pathogen of insects.It lives in the gut of an entomopathogenic nematode of the family Heterorhabditidae.When the nematode infects an insect, "P. luminescens" is released into the blood stream and rapidly kills the insect host (within 48 hours) by producing toxins, such as the high molecular weight insecticidal protein complex Tca.
