Gaudriault, Sophie, Pages, Sylvie, Lanois, Anne, Laroui, Christine, Teyssier, Corinne, Jumas-Bilak, Estelle, ...

Abstract Background The phenotypic consequences of large genomic architecture modifications within a clonal bacterial population are rarely evaluated because of the difficulties associated with using...

Two Distinct Hemolytic Activities in Xenorhabdus nematophila Are Active against Immunocompetent Insect Cells

Brillard, Julien, Ribeiro, Carlos, Boemare, Noël, Brehélin, Michel, Givaudan, Alain

Xenorhabdus spp. and Photorhabdus spp. are major insect bacterial pathogens symbiotically associated with nematodes. These bacteria are transported by their nematode hosts into the hemocoel of the...

flhDC, the Flagellar Master Operon of Xenorhabdus nematophilus: Requirement for Motility, Lipolysis, Extracellular Hemolysis, and Full Virulence in Insects

Givaudan, Alain, Lanois, Anne

Xenorhabdus is a major insect pathogen symbiotically associated with nematodes of the family Steinernematidae. This motile bacterium displays swarming behavior on suitable media, but a spontaneous...

Isolation and Entomotoxic Properties of the Xenorhabdus nematophilus F1 Lecithinase

Thaler, Jacques-Olivier, Duvic, Bernard, Givaudan, Alain, Boemare, Noël

Xenorhabdus spp. and Photorhabdus spp., entomopathogenic bacteria symbiotically associated with nematodes of the families Steinernematidae and Heterorhabditidae, respectively, were shown to produce...

The PhlA Hemolysin from the Entomopathogenic Bacterium Photorhabdus luminescens Belongs to the Two-Partner Secretion Family of Hemolysins

Brillard, Julien, Duchaud, Eric, Boemare, Noël, Kunst, Frank, Givaudan, Alain

Photorhabdus is an entomopathogenic bacterium symbiotically associated with nematodes of the family Heterorhabditidae. Bacterial hemolysins found in numerous pathogenic bacteria are often virulence...

The PhoP-PhoQ Two-Component Regulatory System of Photorhabdus luminescens Is Essential for Virulence in Insects

Derzelle, Sylviane, Turlin, Evelyne, Duchaud, Eric, Pages, Sylvie, Kunst, Frank, Givaudan, Alain, ...

Photorhabdus luminescens is a symbiont of entomopathogenic nematodes. Analysis of the genome sequence of this organism revealed a homologue of PhoP-PhoQ, a two-component system associated with...

Variation in the Effectors of the Type III Secretion System among Photorhabdus Species as Revealed by Genomic Analysis

Brugirard-Ricaud, Karine, Givaudan, Alain, Parkhill, Julian, Boemare, Noel, Kunst, Frank, Zumbihl, Robert, ...

Entomopathogenic bacteria of the genus Photorhabdus harbor a type III secretion system. This system was probably acquired prior to the separation of the species within this genus. Furthermore, the...

Stages of Infection during the Tripartite Interaction between Xenorhabdus nematophila, Its Nematode Vector, and Insect Hosts

Sicard, Mathieu, Brugirard-Ricaud, Karine, Pagès, Sylvie, Lanois, Anne, Boemare, Noel E., Brehélin, Michel, ...

Bacteria of the genus Xenorhabdus are mutually associated with entomopathogenic nematodes of the genus Steinernema and are pathogenic to a broad spectrum of insects. The nematodes act as vectors,...
