"Acute otitis externa, also known as swimmer's ear, is the acute form of otitis externa, an inflammation of the external auditory canal (EAC) with or without involvement of the pinna. Bacterial infection, most commonly with Pseudomonas aeruginosa, is responsible for the overwhelming majority of cases. It is a common condition."
"Pseudomonas aeruginosa, Staphylococcus epidermidis, and Staphylococcus aureus are the most common isolates in descending order in bacterial otitis externa."
"Otomycosis is primarily caused by Aspergillus and Candida spp. It is a common problem in patients with hearing aids or cerumen impaction, which creates a moist environment, facilitating fungal colonisation, but can also result from primary antibiotic therapy for bacterial otitis externa. Pruritus, discharge, and pain are presenting symptoms."

"Acute bacterial otitis externa is common in swimmers; swimming in contaminated lakes and rivers increases the risk of pseudomonal otitis externa."
"Progression of acute bacterial otitis externa to necrotising (a.k.a. malignant) otitis externa is rare; however, of the patients who develop necrotising otitis externa, more than 90% are reported to have glucose intolerance."
