Indeed, the division of the three mechanisms of gene
transfer (transformation, conjugation, and transduction)
may diffuse into grey areas of overlap when describing
transfer in natural environments. It can be envisioned that
a phage may lyse a bacterium containing a conjugative
plasmid, which may transform a bacterium, and then be
transferred by conjugation to second recipient. Transducing
phages could conceivably carry conjugative plasmids or
transposons.
