Plasmids are small circular pieces of double stranded DNA that replicate autonomously. The plasmids within Y. enterocolitica code for the production of the sex pilus and all enzymes necessary for conjugation. Did I just mention the word sex in accordance to bacteria?! No you did not read that incorrectly Yersinia enterocolitica actually undergoes a process called conjugation in which a parental cell passes DNA to a recipient cell via a sex pilus. (To learn more about conjugation click here!) Further, transmission between hosts typically occurs via the fecal oral route.Bacteria wanting to conjugate
