Physiological Constants of the Entomopathogenic Bacterium Xenorhabdus nematophila Determined by Microbial Growth Kinetics
Xenorhabdus nematophila, an entomopathogenic bacterium that symbiotically associates with the entomoparasitic nematode Steinernema carpocapsae, was studied to determine its physiological parameters of glucose utilization. X. nematophila was cultured in chemically defined media containing various concentrations of glucose under optimal conditions utilizing a two-liter fermentation system. Specif...
متن کاملDraft Genome Sequence and Annotation of the Entomopathogenic Bacterium Xenorhabdus nematophila Strain F1
We report the 4.3-Mb genome sequence of Xenorhabdus nematophila strain F1, a Gram-negative bacterium that is a symbiont of the entomopathogenic nematode Steinernema carpocapsae and pathogenic by direct injection for a wide variety of insects.
متن کاملAn entomopathogenic bacterium, Xenorhabdus nematophila, inhibits hemocytic phospholipase A2 (PLA2) in tobacco hornworms Manduca sexta.
The entomopathogenic bacterium, Xenorhabdus nematophila, induces immunodepression in target insects and finally leads to lethal septicemia of the infected hosts. A hypothesis has been raised that the bacteria inhibit eicosanoid-biosynthesis pathway to interrupt immune signaling of the infected hosts. Here, we show direct evidence that X. nematophila inhibits the activity of phospholipase A2 (PL...
متن کاملThe entomopathogenic bacterium, Xenorhabdus nematophila, impairs hemocytic immunity by inhibition of eicosanoid biosynthesis in adult crickets, Gryllus Wrmus
The bacterium, Xenorhabdus nematophila (Poinar and Thomas), is an obligate symbiont of nematodes in the genus Steinernema and a lethal insect pathogen. We investigated the hypothesis that one aspect of the bacterial virulence is the ability of X. nematophila to severely impair host insect cellular immune reactions to infection by inhibiting eicosanoid biosynthesis in the adult male cricket, Gry...
متن کاملMicrobial population dynamics in the hemolymph of Manduca sexta infected with Xenorhabdus nematophila and the entomopathogenic nematode Steinernema carpocapsae.
Xenorhabdus nematophila engages in a mutualistic association with the nematode Steinernema carpocapsae. The nematode invades and traverses the gut of susceptible insects. X. nematophila is released in the insect blood (hemolymph), where it suppresses host immune responses and functions as a pathogen. X. nematophila produces diverse antimicrobials in laboratory cultures. The natural competitors ...
