Otomycosis is a fungal ear infection, [1] a superficial mycotic infection of the outer ear canal caused by micro-organisms called fungi which are related to yeast and mushrooms. It is more common in tropical or warm countries.
Fungal ear canal infections, also known as otomycosis, range from inconsequential to extremely severe. Fungi can be saprophytic, in which there are no symptoms and the fungus simply co-exists in the ear canal in a commensal relationship with the host, in which case the only physical finding is the presence of a fungus. If the fungus begins ...
[1] [7] Systemic fungal infections are more serious and include cryptococcosis, histoplasmosis, pneumocystis pneumonia, aspergillosis and mucormycosis. [3] Signs and symptoms range widely. [3] There is usually a rash with superficial infection. [2] Fungal infection within the skin or under the skin may present with a lump and skin changes. [3]
Otomycosis is the fungal form of Otitis Externa that is more common in coastal regions. Otitis media, or middle ear infection, involves the middle ear. In otitis media, the ear is infected or clogged with fluid behind the ear drum, in the normally air-filled middle-ear space. This is the most common infection and very common in babies younger ...
OTA has been isolated from plant acquired foods products like cereal, vegetables, coffee, wine, liquorice and also animal acquired food products like pork and poultry. [5] Apart from being found in human food products from farm animals, this fungus was also isolated from the poultry feed. [24]
Diagnosing bullous myringitis involves using an otoscope to spot distinctive white sack-like structures on the eardrum.Ear pain is the primary complaint. However, differentiating it from acute otitis media can be difficult, leading to early misdiagnosis.The rarity of bullous myringitis, especially compared to acute otitis media, can result in common misdiagnoses.
Infections can be caused by both bacterial and fungal origin, as well as small organisms such as ear mites. Malassezia pachydermatis is a common fungal agent for ear infections in dogs. Staphylococcus intermedius is the most common bacterial infection. A more serious ear infection, with pus in the ear, may be caused by Pseudomonas aeruginosa.
Aspergillus terreus infection can lead to superficial infections in humans. These affect the outside layer of the body. It is commonly isolated from onychomycosis which is infection of human skin and nails. [9] [10] The incidence of onychomycosis as a result of A. terreus (not the common agent dermatophyte) is increasing.
