Unformatted text preview: It could have been by generalized transduction, providing there were transducing phage growing in at least a subpopulation of the X cells when they were treated with the cleaner, and at least some of the phage were mature, either within an X cell just before lysis or previously released from X cells and on surfaces in the hospital, and the phage were not damaged by the cleaner, and the phage is also able to infect species Y. So while possible, transduction is an unlikely explanation. The most likely explanation seems to be transformation, that when the X cells were lysed, X DNA remained, including fragments carrying the ampicillin resistance gene, and this DNA transformed Y cells, transforming them from ampicillin sensitive to ampicillin resistant....
