  • a The frequencies of temperature-resistant (Tr) cured bacteria were determined about 30 generations after the initial single-cell isolation. Average values are presented. Probe anti, the prophage λTSK is inserted in antiorientation; Probe iso, the prophage λTSK is inserted in iso-orientation. ND, not determined.
