The resilience of listeria monocytogenes to environmental stressors

Introduction: listeria monocytogenes is a significant foodborne pathogen capable of causing severe listeriosis, particularly in vulnerable people [1]. To prevent its spread, effective disinfection strategies are essential. Quaternary ammonium compounds, like benzalkonium chloride, and peracetic acid are commonly used biocides in food processing environments. However, L. monocytogenes can exhibit remarkable resi...

In the quest for reliable tools to explore the virulence potential of Listeria ...

Introduction and objective: Listeria monocytogenes is a foodborne pathogen that causes human listeriosis. This pathogen is characterized by an intra-species heterogeneity so its strains can be grouped into clonal complexes (CCs) that are defined either as hypervirulent – mainly associated with clinical cases or hypovirulent – associated with food or food processing environments and with infections in susceptibl...

Unraveling listeria monocytogenes resilience: does it survive on metallic surfa...

Listeria monocytogenes is a Gram-positive pathogenic bacterium that can cause listeriosis in humans [1,2]. A primary cause of human listeriosis is the consumption of food contaminated with L. monocytogenes. This rare yet severe foodborne illness results in high rates of hospitalization and mortality, particularly in vulnerable groups: the elderly, immunocompromised individuals, and pregnant women [3,4,5]. It ex...

Comparing growth and survival kinetics of persistent and sporadic strains of li...

Motivation: L. monocytogenes is known to persist in food processing environments, with some strains being routinely isolated (persistent), while others are only occasionally found (sporadic). This raises the question: Are persistent strains more resistant to stress conditions compared to sporadic strains from similar sources? Objective: To investigate the effect of food processing related stresses (pH=6 and 8% ...

How resilient are different strains of listeria monocytogenes in cooking salt a...

Introduction: Listeria monocytogenes is a gram-positive pathogenic bacterium responsible for listeriosis in humans and other animals. Human listeriosis is primarily caused by the consumption of foods contaminated with L. monocytogenes. Although rare, this severe foodborne infection leads to high rates of hospitalization and mortality, particularly among vulnerable groups such as the elderly, immunocompromised i...

Current methodologies available to evaluate the virulence potential among Liste...

Listeria monocytogenes is a foodborne pathogen that causes listeriosis in humans, the severity of which depends on multiple factors, including intrinsic characteristics of the affected individuals and the pathogen itself. Additionally, emerging evidence suggests that epigenetic modifications may also modulate host susceptibility to infection. Therefore, different clinical outcomes can be expected, ranging from ...

Variability in Listeria monocytogenes susceptibility to benzalkonium chloride

Introduction: Listeria monocytogenes is a gram-positive pathogenic bacterium that causes severe foodborne listeriosis in humans, transmitted through contaminated foods, with high hospitalization and mortality rates, particularly affecting vulnerable groups: the elderly, immunocompromised individuals, and pregnant women [1]. Quaternary ammonium compounds, such as benzalkonium chloride, are widely used as biocide...

Anti-Listeria potential of bacteriocins from Lactic Acid Bacteria against persi...

Introduction: Listeria monocytogenes is a pathogen responsible for listeriosis, a severe foodborne infection. This bacterium is of particular concern in the food industry due to its ability to persist in food processing environments, increasing the risk of food contamination [1]. However, the mechanisms that facilitate its persistence are poorly understood. Research and development of new technologies, such as ...

Empowering deaf-hearing communication: exploring synergies between predictive a...

Communication between Deaf and hearing individuals remains a persistent challenge requiring attention to foster inclusivity. Despite notable efforts in the development of digital solutions for sign language recognition (SLR), several issues persist, such as cross-platform interoperability and strategies for tokenizing signs to enable continuous conversations and coherent sentence construction. To address such i...

Differentiation between persistent and sporadic Listeria monocytogenes through ...
