Probiotic Potential of Yeasts Isolated from Fermented Beverages: Assessment of Antagonistic Strategies Against Serovar Enteritidis.
J Fungi (Basel)
December 2024
Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET), Godoy Cruz 2290, Ciudad Autónoma de Buenos Aires 1425, Argentina.
Global concern about pathogenic resistance to antibiotics is prompting interest in probiotics as a strategy to prevent or inhibit infections. Fermented beverages are promising sources of probiotic yeasts. This study aimed to evaluate the antagonistic effects of , , and strains from kefir and wine against serovar Enteritidis in intestinal epithelial cells.

In May 2017, whole-genome sequencing (WGS) became the primary subtyping method for in Canada. As a result of the increased discriminatory power provided by WGS, 16 multi-jurisdictional outbreaks of associated with frozen raw breaded chicken products were identified between 2017 and 2019. The majority (15/16) were associated with , while the remaining outbreak was associated with Heidelberg.

Department of Biomolecular Health Sciences, Division of Infectious Diseases and Immunology, Faculty of Veterinary Medicine, Utrecht University, Utrecht, The Netherlands.
The intestinal mucosal barrier is a dynamic system that allows nutrient uptake, stimulates healthy microbe-host interactions, and prevents invasion by pathogens. The mucosa consists of epithelial cells connected by cellular junctions that regulate the passage of nutrients covered by a mucus layer that plays an important role in host-microbiome interactions. Mimicking the intestinal mucosa for assays, particularly the generation of a mucus layer, has proven to be challenging.
