These bacteria enter the middle ear via the eustachian tube. OM may occur following a viral upper respiratory tract infection. The viral infection impairs the eustachian tube\u2019s function, increases mucous production, and helps the bacteria establish an infection in the middle ear. These bacteria may form biofilms making the infection difficult to treat.<\/p>\n\n\n\n<p>The role of&nbsp; Turicella otitidis (Alloiococcus otitidis) in otitis media is not established \u2013 a recent review suggested that it is possible that these organisms are co-pathogens and may contribute to the persistence and recurrence of otitis media.<\/p>\n\n\n\n<p>They probably enter the middle ear through minor tympanic membrane perforations.
