The ability of 30 Listeria monocytogenes strains, 15 of meat origin and 15 of clinical origin, to use carnitine as an osmoprotectant and to resist acid stress was determined. All strains examined were able to use carnitine as an osmoprotectant, indicating the importance of this characteristic to the survival of L. monocytogenes in natural environments. Clinical and meat strains, however, differed with respect to this characteristic. Specifically, 73% of meat strains reached a lower maximum cell… CONTINUE READING
