From: Genomic characterization of Listeria monocytogenes isolates reveals that their persistence in a pig slaughterhouse is linked to the presence of benzalkonium chloride resistance genes

Biofilm formation ability of L. monocytogenes strains from persistent groups A, B and sporadic group C isolated from a pig slaughterhouse at three or four visits (for group B). a) Comparison of biofilm formation ability between the group A, B and C in the absence of BC. b) Comparison of biofilm formation ability between the group A, B and C in the presence of BC. c) Effect of BC at 3.125 and 0.78 ppm on biofilm formation capacity of persistent strains from the group A and B and the sporadic strains C. Significance, n.s: non-significant, ****: p < 0.0001, ***: p = 0.0014.
