| Abstract: | Sublethal concentrations of ethanol or isopropanol increased attachment of Listeria monocytogenes at 10, 20, or 30 degrees C; no induction occurred at 37 degrees C. The alcohol induction phenotype was retained in sigB and cesRK mutants; however, the degree of induction was affected. These results suggest that alcohol may contribute to the persistence of L. monocytogenes. |
