'''Mycoses'''
<br />
<br />
If the mycosis is restricted to superficial tissues, this can be classified as either dermatomycoses or dermatophytoses. Dermatomycoses are usually opportunistic infections of the skin or muco-cutaneous junctions. Often this is caused by ''Candida'' species or ''Malassezia pachydermatis''. Dermatophytoses are clinically more important than dermatomycoses as they are zoonotic and are often associated with the invasion and destruction of keratinised structures such as ''Microsporum'' species and ''Trichophyton'' species.

<br />
Subcutaneous often result following penetration of a foreign body through the superficial layers of the dermis. Systemic mycoses often originate in the respiratory or digestive tracts from opportunistic infections. Factors such as antimicrobial therapy, viral infection or other immuno-suppressors increase the predisposing rick factors to fungal infection.

'''Mycotoxicosis'''
<br />
Mycotoxicoses represent a group of diseases that result from the ingestion of fungal toxins that have been pre-formed in stored food or standing crops.
<br />
<br />
'''Hypersensitivity'''
<br />
Hypersensitivity reactions to to fungal infections are rare but are associated with chronic pulmonary disease in cattle and horses.

===Diagnosis of Fungal Infection===
The main method used to determine the species of mycological infection is by culture. Any culturing procedures should be carried out in a biohazard cabinet due to the zoonotic effect of spores aerosols.
