Acute otitis media (AOM) is an ascending infection associated with Eustachian tube dysfunction during respiratory viral infection, allowing otopathogens to ascend from the nasopharynx to the middle ear. Prevention of AOM plays a significant role in reducing the overall use of antibiotics in children.Lactobacilli, which mainly belong to the microbiome of the gastrointestinal tract, only marginally colonize the nasopharyngeal microbiome and have largely proven ineffective in preventing AOM.
