Molecular Mechanisms of Persistence of Mutualistic Bacteria Photorhabdus in the Entomopathogenic Nematode Host
Symbioses between microbes and animals are ubiquitous, yet little is known about the intricate mechanisms maintaining such associations. In an emerging mutualistic model system, insect-pathogenic bacteria Photorhabdus and their insect-parasitic nematode partner Heterorhabditis, we found that the bacteria undergo major transcriptional reshaping in the nematode intestine. Besides general starvati...
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.
متن کاملIsolation and Identification of Photorhabdus Luminescens an Insect Pathogenic Bacteria Associated with Entomopathogenic Nematode
Photorhabdus luminescens is a gram negative symbiotic bacterium belonging to the family Enterobacteriaceae, 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. luminescensis released into the blood stream and rapidly kills the insect host by producing toxins. So the present study was ca...
متن کاملPhotorhabdus Species: Bioluminescent Bacteria as Human Pathogens?
We report two Australian patients with soft tissue infections due to Photorhabdus species. Recognized as important insect pathogens, Photorhabdus spp. are bioluminescent gram-negative bacilli. Bacteria belonging to the genus are emerging as a cause of both localized soft tissue and disseminated infections in humans in the United States and Australia. The source of infection in humans remains un...
متن کاملWhole-genome comparison between Photorhabdus strains to identify genomic regions involved in the specificity of nematode interaction.
The bacterium Photorhabdus establishes a highly specific association with Heterorhabditis, its nematode host. Photorhabdus strains associated with Heterorhabditis bacteriophora or Heterorhabditis megidis were compared using a Photorhabdus DNA microarray. We describe 31 regions belonging to the Photorhabdus flexible gene pool. Distribution analysis of regions among the Photorhabdus genus identif...
