DNA from related species can kill certain pathogens when they incorporate it into their genome!
Microbe of the episode
Microbe of the episode: Ungulate tetraparvovirus 3
This study showed that when N. gonorrhoeae takes up DNA from harmless, commensal species of Neisseria in the body, the DNA is similar enough to be incorporated into the genome but different enough that it kills the pathogen. This effect also occurs with a serious pathogen in the same genus, N. meningitidis.
