25 de ene. de 2019 · Biofilm y Listeria monocytogenes persistente. Listeria monocytogenes es uno de los patógenos alimentarios que causa una mayor preocupación en la industria, debido a su alto índice de mortalidad y a su capacidad para sobrevivir en condiciones adversas para otros microorganismos.
La capacidad de formación de biopelículas de L. monocytogenes depende de una serie de factores, ya sea relacionados a las propiedades fisicoquímicas de la superficie y a la hidrofobicidad, pH, temperatura y composición de nutrientes; o relacionados a las cepas, como el serotipo.
9 de jun. de 2021 · Listeria monocytogenes is a highly pathogenic foodborne bacterium that is ubiquitous in the natural environment and capable of forming persistent biofilms in food processing environments. This species has a rich repertoire of surface structures that enable it to survive, adapt and persist in various environments and promote biofilm formation.
21 de nov. de 2019 · Concerns about food contamination by Listeria monocytogenes are on the rise with increasing consumption of ready-to-eat foods. Biofilm production of L. monocytogenes is presumed to be one of the ways that confer its increased resistance and persistence in the food chain.
Hace 9 horas · Listeria monocytogenes (L. monocytogenes) is a foodborne pathogen that causes listeriosis in humans and other animals. Surface proteins with the LPXTG motif have important roles in the virulence of L. monocytogenes. Lmo0159 is one such protein, but little is known about its role in L. monocytogenes virulence, motility, and biofilm formation. Here, we constructed and characterized a deletion ...
21 de nov. de 2019 · Concerns about food contamination by Listeria monocytogenes are on the rise with increasing consumption of ready-to-eat foods. Biofilm production of L. monocytogenes is presumed to be one of the ways that confer its increased resistance and persistence in the food chain. In this study, …
2 de oct. de 2022 · The aims of this study were: i) to assess the biofilm producing ability of 57 Listeria monocytogenes isolates previously subjected to whole-genome sequencing (WGS); ii) to compare the levels of biofilm formation with the presence or absence of biofilm associated genes.
