title: Bacterial mutation affecting plasmid maintenance in Pseudomonas aeruginosa.
abstract: A bacterial mutation, risA, in Pseudomonas aeruginosa caused growth inhibition at 43 degrees C of risA strains containing P2 plasmids. Incubation at 43 degrees C resulted in selection for clones that had lost P2 plasmids.
