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. In contrast, in this study, the presence of hair was not found in any of the histopathology, and abscesses were present in the periorbital area. S. aureus colonises the skin, nasopharynx and intestines, and may cause pyogenic infections if a breach in local defences promotes staphylococcal invasion. Whole genome sequencing and analysis supported the hypothesis that this outbreak resulted from clonal expansion of S. aureus infected C57BL6\/J mice imported into the area and infection transmission from humans to mice was ruled out. An additional aetiopathogenesis is proposed for S. aureus abscesses with the sharp edges of damaged plastic environmental enrichment items leading to oral mucosal injury allowing S. aureus entrance into tissues, its carriage into the submucosa, followed by abscess formation.<\/jats:p>","DOI":"10.1177\/00236772221146844","type":"journal-article","created":{"date-parts":[[2023,1,13]],"date-time":"2023-01-13T02:48:46Z","timestamp":1673578126000},"page":"341-349","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["The role of environmental enrichment in the aetiopathogenesis of\n                    <i>Staphylococcus aureus<\/i>\n                    facial, periorbital and retroorbital abscesses in mice"],"prefix":"10.1177","volume":"57","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6135-3278","authenticated-orcid":false,"given":"Jos\u00e9 M","family":"S\u00e1nchez-Morgado","sequence":"first","affiliation":[{"name":"Bioresearch and Veterinary Services, The University of Edinburgh, Edinburgh, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2023,1,12]]},"reference":[{"key":"bibr1-00236772221146844","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-12-409527-4.00003-1"},{"key":"bibr2-00236772221146844","doi-asserted-by":"publisher","DOI":"10.17265\/2159-5313\/2016.09.003"},{"key":"bibr3-00236772221146844","doi-asserted-by":"publisher","DOI":"10.1016\/j.tim.2011.01.007"},{"key":"bibr4-00236772221146844","volume-title":"Manual of microbiologic monitoring of laboratory animals","author":"Shimizu A.","year":"1994"},{"key":"bibr5-00236772221146844","first-page":"200","volume":"60","author":"Lawson GW.","year":"2010","journal-title":"Comp Med"},{"key":"bibr6-00236772221146844","first-page":"25","volume":"31","author":"Grant N","year":"2002","journal-title":"Lab Anim"},{"key":"bibr7-00236772221146844","doi-asserted-by":"publisher","DOI":"10.1258\/002367778780936296"},{"key":"bibr8-00236772221146844","first-page":"270","volume":"31","author":"McBride DF","year":"1981","journal-title":"Lab Anim Sci"},{"key":"bibr9-00236772221146844","first-page":"359","volume":"150","author":"Shapiro RL","year":"1997","journal-title":"Am J Pathol"},{"key":"bibr10-00236772221146844","first-page":"280","volume":"44","author":"Wardrip CL","year":"1994","journal-title":"Lab Anim Sci"},{"key":"bibr11-00236772221146844","doi-asserted-by":"publisher","DOI":"10.1258\/002367794781065933"},{"key":"bibr12-00236772221146844","doi-asserted-by":"publisher","DOI":"10.1258\/002367796780684881"},{"key":"bibr13-00236772221146844","author":"M\u00e4hler M","year":"2014","journal-title":"Lab Anim"},{"key":"bibr14-00236772221146844","doi-asserted-by":"publisher","DOI":"10.1258\/0023677021911740"},{"key":"bibr15-00236772221146844","doi-asserted-by":"publisher","DOI":"10.1016\/j.molmed.2018.12.010"},{"key":"bibr16-00236772221146844","unstructured":"Health Products Regulatory Authority.
