A mouse model of Staphylococcus aureus small intestinal infection.

ABSTRACT: Introduction. Staphylococcus aureus is a recognised cause of foodborne intoxication and antibiotic-associated diarrhoea (AAD), which are both mediated by staphylococcal enterotoxins. However, unlike foodborne intoxication, AAD appears to require infection of the host. While S. aureus intoxication is widely studied, little is known about S. aureus pathogenesis in the context of gastrointestinal infection.Aim. To develop a mouse model of S. aureus gastrointestinal infection.Methodology. An established AAD mouse model was adapted for S. aureus infection, and damage observed via histopathological analysis and immunostaining of intestinal tissues.Results. Various strains colonised the mouse model, and analysis showed that although c
