Development of 3 dimensional in vitro models of bone infection (Immunobact)
Background
Staphylococcus aureus is a prominent pathogen in bone-related infections where it can form staphylococcal abscess communities (SACs). SACs are a dense population of S. aureus within a fibrin pseudocapsule and are implicated in fracture related infection.
Goal
To establish an in vitro SAC model that resembles in vivo SACs.
