Norepinephrine and Serotonin Can Modulate the Behavior of the Probiotic Enterococcus faecium NCIMB10415 towards the Host: Is a Putative Surface Sensor Involved?

Rossella Scardaci et al.

Summary: This study explores the phenotypic and interactive responses of the probiotic Enterococcus faecium NCIMB10415 to the neuroactive molecules norepinephrine (NE) and serotonin (5HT) abundant in the gut, providing insights into the crucial relationship between human gut microbiota and humans. The results demonstrate that E. faecium NCIMB10415 can sense both NE and 5HT and respond accordingly.

Enterococcus spp.: Is It a Bad Choice for a Good Use-A Conundrum to Solve?

Mounir Ferchichi et al.

Summary: Enterococci face challenges in terms of virulence determinants and antimicrobial resistance, hindering their potential use as probiotics in food. The possible transmission of virulent strains through food consumption makes them unsuitable as probiotics. Selected enterococcal strains for use in food should lack virulence genes and be susceptible to clinically relevant antibiotics.

New Insights into the Virulence Traits and Antibiotic Resistance of Enterococci Isolated from Diverse Probiotic Products

Fengru Deng et al.

Summary: Enterococci, commonly used as probiotics, have not been officially recognized as safe, but have been increasingly used in human healthcare and animal husbandry. A study found that some commercial probiotic products contained undisclosed enterococci, with some showing hemolysis.

The Many Faces of Enterococcus spp.-Commensal, Probiotic and Opportunistic Pathogen

Beata Krawczyk et al.

Summary: Enterococcus spp. are Gram-positive, anaerobic cocci commonly found in the intestinal flora. While they play a role in modulating the immune system and have been used as probiotics, concerns arise over their antibiotic resistance and potential pathogenicity.
