Rhinosporidiosis

 

a serious chronic mycosis in animals and man characterized by the formation of polypous growths on the mucosa of the nose, eyes, ears, larynx, and other organs. Rhinosporidiosis was first described in animals in 1892 in Argentina. The causative agent is the fungus Rhinosporidium seeberi.

Many researchers believe that rhinosporidiosis is a disease that affects fish, and that man and mammals are accidental hosts of the parasite. The fungus invades the organism with dust or water. Diagnosis is based on clinical symptoms and the results of laboratory tests. Treatment includes cauterization and the excision of the polyps. No specific preventive measures have been developed.
