The primary pathogens responsible for acute otitis media (AOM) include:
- Streptococcus pneumoniae: This is the most common bacterial cause of AOM.
- Haemophilus influenzae (non-typeable): Another frequent bacterial pathogen.
- Moraxella catarrhalis: Less common but still a significant cause.
- Group A Streptococcus: Can also cause AOM, though less frequently than the above pathogens.
These bacteria often follow viral upper respiratory tract infections, which can set the stage for secondary bacterial infections in the middle ear oai_citation:1,Otitis Media: Rapid Evidence Review | AAFP oai_citation:2,Clinical Practice Guidelines : Acute otitis media.

extremities of growing active children.
children between 2 and 12 years with the peak
incidence in preschool children.
mostly felt in the thighs, calves and
behind the knee.
intermittent and in mostly present in the afternoon and evening after activity during the day.

- antalgic gait with limited hip motion, or a Trendelenburg gate (abductor lurch).
- Pain may be present with passive range of motion and
limited hip movement, especially internal rotation and abduction
