Mycosis is a fungal infection of animals,including humans.mycoses are common and a variety of physiological and environmental conditions can contribute to the development of fungal diseases.Inhalation of fungal spores or localized colonization of the skin may initiate persistent infections,therefore mycoses often start in the lungs or on the skin.
Systemic mycosis due to opportunistic pathogens are infections of patients with immune deficiencies who would otherwise not be infected..Examples of immunocompromised conditions include AIDS, alteration of normal flora by antibiotics ,immunosuppressive therapy, and metastatic cancer.Examples of opportunistic mycoses include Candidiasis, Cryptococcosis and Aspergillosis.
Causes of immunodeficiency commonly encountered are:
1.Malignancies(Leukemias ,lymphomas,Hodgkin's disease)
2. Drug therapies:Anti-neoplastic substances,steroids,immuno-suppressive drugs
3.Antibiotics:Overuse or inappropriate use of antibiotics can also contribute to the development of fungal infections by altering the normal flora of host and facilitating fungal overgrowth or by selecting for resistant organisms.
Other factors associated with increased frequency of mycotic infections are:
Severe burns
Diabetes
Tuberculosis
I. V. Drug use
AIDS
