Phycomycosis(redirected from Pythiosis)
Also found in: Dictionary, Thesaurus, Medical.
an infectious disease of farm animals (mainly the young), as well as mink and fish, caused by pathogenic fungi of the family Mucoraceae. The disease also affects humans. Infection takes place through the respiratory organs, the alimentary canal, injured skin, or mucous membranes, in which nodules of tissue (granulomas) and suppurative ulcers form. The disease affects the viscera, mainly the intestine and lungs, the skin of the extremities and head, and the mucous membranes of the nose and its accessory sinuses. Depending on the site of infection, animals may suffer from diarrhea, exhaustion, swelling of the subcutaneous lymph nodes, ulceration of the skin and nasal septum, and miscarriage.
An effective means of treating phycomycosis has not been developed. Prevention mainly includes the observance of sanitary conditions in housing and feeding animals. Supervising the quality of feed is especially important.
