Pertaining to a mycosis; caused by fungi. Fungal infections occur in most organs of the body, e.g. mycotic mastitis, keratitis, hepatitis, rumenitis, colitis.
- m. abortion — is common only in cattle and is caused by Mortierella wolfii, Mucor and Aspergillus spp. Petriellidium boydii (Allescheria boydii) is also recorded as a cause.
- m. dermatitis — the name is a misnomer because it is caused by a bacterium Dermatophilus dermatonomus. It occurs in all species but is a disease of high prevalence only in cattle and sheep. Lesions are worst on the dorsal parts of the body. They are thick, tenacious scabs, difficult to remove, underrun by granulation tissue. Continual wetness is an exacerbant. In sheep the lesions are in the woolled parts and damage the fleece badly. There is often vivid discoloration.
- m. granuloma — see swamp cancer.
- m. lymphangitis — see bovine farcy.
- m. nasal granuloma — a disease of cows, characterized by noisy and distressed breathing and nasal discharge. There are large polyps containing yellow-green granulation tissue in the nasal cavities. Histologically the lesions are eosinophilic granulomas containing fungal elements. Drechslera rostrata has been isolated from the lesions. Rhizobium spp. fungus is also recorded as a cause in cattle.
- m. stomatitis — is regarded as a secondary lesion produced by the invasion of devitalized tissue or existing mucosal lesions by fungi, especially Candida spp. Characterized by a growth of soft, white, elevated patches, which are felted masses of mycelia on an inflamed or ulcerated mucosa. Occurs especially in very young animals still drinking milk. The lesions usually extend into the pharynx and in fatal cases further still down the alimentary tract.
