Table 3 In silico and phenotypic characteristics of L. monocytogenes strains from group A, B, and C isolated from an industrial slaughterhouse over a four weeks or three years (for Lis8216) period; In silico identification of determinants for persistence. Phenotypic determination of resistance to BC in L. monocytogenes strains isolated: Minimal inhibitory concentrations of all isolates. PCR screening test to identify the bcrABC cassette in the studied strains
