Background And Objectives: The most common cause of severe foodborne salmonellosis is Typhimurium. Its interaction with intestinal epithelial cells is little known. Lactic acid bacteria (LAB) were recognized as a prominent probiotic gastrointestinal microbiota of humans and animals that confer health-promoting and protective effects.

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.

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.

Introduction: is a notorious foodborne pathogen, frequently contaminating powdered infant formula and causing life-threatening diseases in infants. The escalating emergence of antibiotics-resistant mutants has led to increased interest in using bacteriophage as an alternative antimicrobial agent.
Methods: Two phages, CR8 and S13, were isolated from feces and soil samples and their morphology, physiology, and genomics were characterized.
Electric field-induced alignment of Ag/Au nanowires for ultrasensitive in situ detection of Interleukin-6.

Interleukin-6 (IL-6) is a key parameter and critical role in cancer progression. However, for detection of IL-6 in colorectal cancer diagnosis, developing a sensitive biosensor is necessary and very important. In this paper, to enhance the sensitivity of IL-6 electrochemical biosensor, the electric field was used to orient arrangement of silver nanowires (AgNWs) to be free-standing AgNWs electrode.
