This paper discusses how nematodes interact with beneficial and antagonistic organisms, including members of their own species, what causes interactions to occur, and how these interactions affect nematode behaviour. It describes different types of interactions, e.g. phoresy, antagonism, predation...

This paper describes the Vibrio fischeri-squid model system. The various stages of the bacteria-nematode symbiosis are discussed in detail and compared with the bacteria-squid system. Notable differences between the Photorhabdus-Heterorhabditis and Xenorhabdus-Steinernema systems are presented.

An outcome of research into the biology of the symbiosis of entomopathogenic nematodes and their associated bacteria has been the discovery of the diversity of chemical substances, some of them new to science, produced by bacterial symbionts. This paper focuses on these secondary metabolites,...
