The effect of blood on the ability of biofilm formation by Listeria monocytogenes strains

Abstract

Introduction: Listeria monocytogenes strains are widespread in the natural environment and are the

Influence of the food matrix on dual-species biofilm of Listeria monocytogenes and Pseudomonas fluorescens

“…An important parameter in determining whether there is bacterial adhesion or mature biofilm formation is the number of microorganisms present on the surface. Counts upper 5 log 10 CFU cm -2 are considered to have mature biofilm (Wiktorczyk et al, 2018;Alonso & Kabuki. 2019;Ramires et al, 2021).…”

“…A total of 14 bacteria were used in this study: four species belonging to L. monocytogenes, four of L. innocua and four belonging to species L. seeligeri. In addition to these isolates, the standard strains L. monocytogenes ATCC 35152 and L. monocytogenes ATCC 7644 were also used in the study (Kumar et al, 2009;Wiktorczyk, Grudlewska, Skowron, Gryń, & Gospodarek-Komkowska, 2018)…”

Prevalence and antimicrobial susceptibility of Listeria monocytogenes strains isolated from a meat processing plant

“…The biofilm structure makes the eradication of bacteria from such a community much more difficult than their planktonic forms [16,36,37,38]. It has been shown (Smith and Hunter, 2008), that bacterial cells in the biofilm structure differ phenotypically from cells in the planktonic form, especially in the degree of resistance to disinfectants.…”
