A metalloprotease secreted by the insect pathogen Photorhabdus luminescens induces melanization.
Photorhabdus luminescens is a gram-negative insect pathogen that enters the hemocoel of infected hosts and produces a number of secreted proteins that promote colonization and subsequent death of the insect. In initial studies to determine the exact role of individual secreted proteins in insect pathogenesis, concentrated culture supernatants from various P. luminescens strains were injected in...
متن کاملA zinc metalloprotease inhibitor, Inh, from the insect pathogen Photorhabdus luminescens.
The entomopathogen Photorhabdus luminescens secretes many proteins during the late stages of insect larvae infection and during in vitro laboratory culture. The authors have previously characterized and purified a 55 kDa zinc metalloprotease, PrtA, from culture supernatants of P. luminescens. PrtA is secreted via a classical type I secretory pathway and is encoded within the operon prtA-inh-prt...
متن کاملFor the insect pathogen Photorhabdus luminescens, which end of a nematode is out?
The nematode Heterorhabditis bacteriophora is the vector for transmitting the entomopathogenic bacterium Photorhabdus luminescens between insect larvae. The dauer juvenile (DJ) stage nematode selectively retains P. luminescens in its intestine until it releases the bacteria into the hemocoel of an insect host. We report the results of studying the transmission of the bacteria by its nematode ve...
متن کاملThe emerging human pathogen Photorhabdus asymbiotica is a facultative intracellular bacterium and induces apoptosis of macrophage-like cells.
Photorhabdus species are gram-negative entomopathogenic bacteria of the family Enterobacteriaceae. Among the different members of the genus, one species, Photorhabdus asymbiotica, is a pathogen of both insects and humans. The pathogenicity mechanisms of this bacterium are unknown. Here we show that P. asymbiotica is a facultative intracellular pathogen that is able to replicate inside human mac...
متن کاملNematode Symbiont for Photorhabdus asymbiotica
Photorhabdus asymbiotica is an emerging bacterial pathogen that causes locally invasive soft tissue and disseminated bacteremic infections in the United States and Australia. Although the source of infection was previously unknown, we report that the bacterium is found in a symbiotic association with an insect-pathogenic soil nematode of the genus Heterorhabditis.
