In brief: Bacteria

The 3 most common bacteria to cause middle ear infections (otitis media) are streptococcus pneumoniae, haemophilus influenzae and moraxella catarrhalis.
Otitis media can also be a viral infection. Swimmer's ear or otitis externa is mostly from pseudomonas aeruginosa. Other swimmer's ear germs include staph aureus, enterobacter aerogenes, proteus mirabilis, klebsiella pneumoniae and fungi.
