Rhabditis is an excellent laboratory model to study internal gene transfer because (a) these microbial worms are bacterial feeders which vector viable bacteria (Chang et al.
These conditions suggested a high probability of interaction events and, indeed, conjugation was detected within the intestinal tract of Rhabditis and transconjugants were identified using various selective media (Adamo and Gealt, 1994; 1996a; Leighton et al.
Nematodes were examined microscopically, measured, and individuals of the genus Rhabditis were selected for further study.
