Genetic Diversity and Epidemiological Overlap of Staphylococcus aureus at the Animal–Food–Environment–Human Interface Within a One Health Framework

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Integrating farm‐to‐fork and clinical surveillance, this study reveals distinct SCCmec distributions alongside shared spa types across human, animal, and food interfaces. The results of genetic diversity and epidemiological overlap underscore the critical need for coordinated One Health surveillance to monitor multi‐sectoral Staphylococcus aureus ...

Staphylococcal enterotoxins in the Etiopathogenesis of Mucosal Autoimmunity within the Gastrointestinal Tract

Toxins, 2014
The staphylococcal enterotoxins (SEs) are the products of Staphylococcus aureus and are recognized as the causative agents of classical food poisoning in humans following the consumption of contaminated food.

Mucosal‐Associated Invariant T Cells in Health and Disease

MedComm, Volume 7, Issue 10, October 2026.
The roles of MAIT cells in health and disease and their therapeutic applications. In healthy individuals, riboflavin metabolites secreted by commensal bacteria at mucosal sites are presented by MR1, leading to the activation of MAIT cells. Activated MAIT cells can maintain the barrier integrity of mucosal tissues in a steady state or migrate to the ...

Mast Cells in Host Defense Against Cutaneous Staphylococcus aureus Infection

Immunology &Cell Biology, Volume 104, Issue 9, Page 867-880, October 2026.
Impact of S. aureus epicutaneous sensitization models on mast cell function in vivo. D. farinae and Staphylococcal enterotoxin B (SEB) activate Trpv1+ Tac1+ nociceptors to trigger the release of substance P (SP), which promotes mast cell degranulation through Mrgprb2. S.

Engineering Human Donor Derived Germinal Center‐Like Organoids (GCLOs) for Studying Immune Response to Vaccination

Advanced Science, Volume 13, Issue 53, 24 September 2026.
We bioengineered a new approach methodology of generating Germinal Center Organoids that self‐organize from human blood‐derived immune cells. These immune organoids reproduce key features of humoral immunity, IgG production, and plasmablast emergence.

Evidence that staphylococcal superantigens promote within-patient bacterial persistence following post-operative surgical site infection

Infection and Immunity
Staphylococcus aureus is a predominant cause of post-operative surgical site infections and persistent bacteremia. Here, we describe a patient who experienced three episodes of S.

Determining the immunological characteristics of a novel human monoclonal antibody developed against staphylococcal enterotoxin B

Human Vaccines & Immunotherapeutics, 2020
Staphylococci are the main cause of nosocomial infections globally. The exotoxin staphylococcal enterotoxin B (SEB) produced by methicillin-resistant Staphylococcus aureus is a major cause of pathology after a staphylococcal infection.
