To model and study the various complexities of AOM, common human otopathogens are injected directly into the middle ear bullae of rodents or are delivered with viral co-infections which contribute to the access to the middle ears in complex and partially understood ways. Here, we present the novel observation that <jats:italic>Bordetella bronchiseptica<\/jats:italic>, a well-characterized respiratory commensal\/pathogen of mice, also efficiently ascends their Eustachian tubes to colonize their middle ears, providing a flexible mouse model to study naturally occurring AOM. Mice lacking T and\/or B cells failed to resolve infections, highlighting the cooperative role of both in clearing middle ear infection. Adoptively transferred antibodies provided complete protection to the lungs but only partially protected the middle ears, highlighting the differences between respiratory and otoimmunology. We present this as a novel experimental system that can capitalize on the strengths of the mouse model to dissect the molecular mechanisms involved in the generation and function of immunity within the middle ear.<\/jats:p>","DOI":"10.3389\/fcimb.2021.815627","type":"journal-article","created":{"date-parts":[[2022,1,24]],"date-time":"2022-01-24T05:42:58Z","timestamp":1643002978000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":8,"title":["Probing Immune-Mediated Clearance of Acute Middle Ear Infection in Mice"],"prefix":"10.3389","volume":"11","author":[{"given":"Kalyan K.","family":"Dewan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Colleen","family":"Sedney","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amanda D.","family":"Caulfield","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yang","family":"Su","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Longhuan","family":"Ma","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Uriel","family":"Blas-Machado","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eric T.","family":"Harvill","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2022,1,24]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"12","DOI":"10.1001\/archotol.125.1.12","article-title":"Measuring the Indirect and Direct Costs of Acute Otitis Media","volume":"125","author":"Alsarraf","year":"1999","journal-title":"Arch.
