Abstract

The bacterium Achromobacter nematophilus, which has been isolated from two populations of nematodes belonging to the genus Neoaplectana, was found to be extremely lethal to larvae of Galleria mellonella when injected into the hemocoel. Although producing no obvious effects if fed per os, when one to three bacterial cells were introduced into the body cavity, the insects usually died. In nature, this bacterium occurs in the body of insects attacked by certain neoaplectanid nematodes and, between periods of insect infection, inside the gut of infective stage nematodes. The cells are very fastidious and appear to have a very transient existence in soil or water.

    Citation Excerpt :

    Upon finding of a suitable insect host, Steinernema IJs must establish in the insect hemocoel. Insect hemolymph triggers IJs molting and the release of Xenorhabdus [23,55]. Undoubtedly, Xenorhabdus play a key role in the killing of the insect host by producing various virulence factors [e.g. toxins, hemolysins, lipases, proteases] that contribute to the death of the insect within 24–48 hours [56,57].
