Fungal infections, e.g. aspergillosis, may form fungal balls, cause sinusitis, or rarely be invasive. Other fungi may affect this region, but they are more commonly seen in Asia and Africa. Rhinosporidiosis, caused by Rhinosporidium seeberi, is transmitted by cattle and horses, and causes granulomatous nasal polyps.

Rhinosporidiosis is an infectious disease caused by an aquatic protozoan previously considered to be a fungus. The aetiologic agent of rhinosporidiosis, Rhinosporidium seeberi, is closely related to several protoctistiae fish pathogens. The infection affects nasal mucous membranes and ocular conjunctivae of humans and animals, producing slowly growing masses that degenerate into polyps. As this is no longer considered to be a fungal pathogen it will be considered no further in this chapter.

Rhinosporidiosis [Greek: rhin, nose + sporos, seed] Involving the mucocutaneous tissue of the nose, was noted in Argentina by Alejandro Posadas (1870–1920) of Buenos Aires in 1903. This diseases is also common in India and was described by O’Kinealy in the same year. James Hartley Ashworth (1874–1936) of Edinburgh proposed the genus Rhinosporidium as the causative fungus of the disease in 1923.

Rhinosporidiosis is a chronic granulomatous infection of the mucous membranes of the nose or external structures of the eye that usually manifests as vascular friable polyps. Rhinosporidiosis is endemic in India, Sri Lanka, South America, and Africa.4 Molecular biological techniques have more recently demonstrated the causative organism Rhinosporidium seeberi to be an aquatic protistan parasite, and it has been placed into a new class, the Mesomycetozoea, along with organisms that cause similar infections in amphibians and fish.5 However, another molecular study has demonstrated evidence that R seeberi may have host-specific strains (e.g., human vs dog vs swan).6
