penetrans has two main steps: first an external adhesion of free spores on the nematode cuticle in the soil which depends on attachment compatibility between bacterial spores and nematodes (Davies and Redden 1997) and on the population densities of each organism (Stirling 1991) second an internal infection when nematodes after reaching the roots and start feeding spores germinate penetrate through the nematode cuticle colonize the nematode coelome (Sayre and Starr 1985; Chen and Dickson 1998) and produce new spores which are released in soil after nematode death.
