    “…In this observational retrospective study, an outbreak of Staphylococcus aureus abscesses was correlated with the presence of sharp edges in damaged plastic environmental enrichment within the cages. In 2010, Lawson reported cases of S. aureus mandibulofacial and maxillofacial abscess in mice and proposed excessive barbering or grooming, leading to the mastication and fragmentation of hair, as an aetiopathogenesis of S. aureus abscesses. …”
