Transcriptomic Response of Listeria monocytogenes throughout the Life Cycle

ABSTRACT: A long-term-survival (LTS) phase in Listeria monocytogenes was recently discovered. Cells in this phase are coccoid in shape, survive for at least 30 d without any decrease in viable cell numbers, and are very resistant to heat and high pressure. However, how cells of L. monocytogenes transition to this long-term-survival phase is little understood. Therefore, a whole-genome expression analysis was conducted to study the transcription profile of L. monocytogenes as it enters the LTS phase. Transcription profiles at log, stationary and death phases were analyzed since differential gene expressions at these phases may contribute to the eventual transition to the LTS phase. Specifically, cells of L. monocytogenes F2365 at log, stationary, death and LTS phases were obtained by incubating
