What are the four typical types of opportunistic mycoses?
Opportunistic Mycoses
- Candidiasis. Candidiasis (due to C albicans and other Candida spp.) is the most common opportunistic fungal infection.
- Aspergillosis. Invasive aspergillosis most frequently involves the lungs and paranasal sinuses.
- Zygomycosis.
- Cryptococcosis.
- Phaeohyphomycosis.
- Hyalohyphomycosis.
What are systemic mycoses and opportunistic mycoses?
Systemic fungal infections can be primary or opportunistic. The mycoses caused by opportunistic pathogens become increasingly more important. These infections are mainly caused by Candida species, Aspergillus species, Cryptococcus neoformans, Mucor etc.
Which of the following are opportunistic fungi?
Aspergillus and Candida spp. are the main organisms isolated most frequently from immunocompromised patients. The other most relevant aetiologic agents are Cryptococcus spp., Fusarium spp., Zygomycete, Dematiaceous fungi and opportunistic yeast-like fungi9.
Which factors increase risk for opportunistic mycoses?
Conditions that predispose patients to any of the opportunistic fungal pathogens are as follows:
- Acute leukemia or lymphoma during myeloablative chemotherapy.
- Bone marrow or peripheral blood stem cell transplantation.
- Solid organ transplantation on immunosuppressive treatment.
- Prolonged corticosteroid therapy.
Which of the following diseases is the example of opportunistic mycoses?
Examples of opportunistic mycoses include Candidiasis, Cryptococcosis and Aspergillosis.
What are systemic mycoses?
Systemic mycoses are fungal infections affecting internal organs. In the right circumstances the fungi enter the body via the lungs, through the gut, paranasal sinuses or skin.
Which of the following disease is the example of opportunistic mycoses?
Why are fungi called opportunistic?
Opportunistic fungi refers to those fungi that normally would not cause infections in otherwise healthy people but are able to cause infection under certain circumstances such as immunodefficiency, cancer, organ transplant, neutropenic patients, diabetes, debilitated patients and patients on long term antibiotics.
Are all fungi opportunistic?
Many fungi are opportunists and are usually not pathogenic except in an immunocompromised host.
What medical conditions predispose to opportunistic mycoses?
Predisposing factors include prolonged neutropenia, especially in leukemia patients or in bone marrow transplant recipients, corticosteroid therapy, cytotoxic chemotherapy and to a lesser extent patients with AIDS or chronic granulomatous disease.
