In laboratory, some species are virulent directly injected within the insect host, whereas others species need the nematode to penetrate into the insect. In the non-infestant-stage nematode living in the soil, Xenorhabdus spp. are carried in a specialized region of the intestine, termed the receptacle. Xenorhabdus nematophila colonizes the entire intestinal receptacle . After inducing host immunosuppression, the bacteria multiply in the hemocoel and cause fatal septicemia. 2006, A sequential optimization approach based on statistical experimental designs was employed to optimize growth medium and fermentation conditions, in order to improve the antibiotic activity of Xenorhabdus nematophila TB.

Alternative Names achromobacter nematophilus, xenorhabdus nematophila subsp. Under SOS conditions, xenocin is produced with immunity protein as a complex. Part of its pathogenicity is due to impairing cellular immunity by blocking biosynthesis of eicosanoids, the major recognized signal transduction system in insect cellular immunity. Singh, S, Orr, D, Divinagracia, E, McGraw, J, Dorff, K, and Forst, Steven A. JS Rathore, Y Wang.

Summary As an insect pathogen, the γ‐proteobacterium Xenorhabdus nematophila likely possesses an arsenal of virulence factors, one of which is described in this work. In this study we analyzed the P2-type remnant prophage clusters in the draft sequences of nine strains of Xenorhabdus bovienii. Xenorhabdus nematophilia could possibly be used for its production of antibiotics and other useful natural products, but so far no such use has been commercialized. The majority of these antibiotics were developed between 1940 and 1962 (Coates et al., 2011). We present evidence that the X . Its behavior is thus probably shaped by all these constraints.
