Abstract

Sixty-six strains ofListeria monocytogenes (as defined in the eighth edition ofBergey's Manual of Determinative Bacteriology) were characterized by DNA relatedness. These strains formed five distinct DNA relatedness groups: (i)L. monocytogenes sensu stricto (30 strains) including the type spain ATCC 15313; (ii) serovar 5 strains (9 strains) corresponding to “L. bulgarica”; (iii) “L. inocua” (11 strains of serovars 6a, 6b, 4ab, and undesignated ones) including the reference strains; (iv) six strains of serovars 6a and 6b; (v) ten strains of various serovars. These five groups were clearly distinct fromL. grayi (4 strains) andL. murrayi (3 strains).
