Abstract. Thirty-one Listeria strains were tested for sensitivity to four class IIa bacteriocins, namely, enterocin A, mesentericin Y105, divercin V41, and pediocin AcH, and to nisin A. Class IIa bacteriocins displayed surprisingly similar antimicrobial patterns ranging from highly susceptible to fully resistant strains, whereas nisin A showed a different pattern in which all Listeria strains were inhibited. Particularly, it was observed that the strain Listeria monocytogenes V7 could not be inhibited by any of the class IIa bacteriocins tested. These observations suggest that Listeria strains resistant to the whole range of class IIa bacteriocins may occur in natural environments, which could be of great concern with regard to the use of these peptides as food preservatives.
