The plasmid-borne hipBA operon of Klebsiella michiganensis encodes a potent plasmid stabilization system.

Aims: Klebsiella michiganensis is a medically important bacterium that has been subject to relatively little attention in the literature. Interrogation of sequence data from K. michiganensis strains in our collection has revealed the presence of multiple large plasmids encoding type II toxin-antitoxin (TA) systems.
