Mucorales: An order of zygomycetous fungi, usually saprophytic, causing damage to food in storage, but which may cause respiratory infection or MUCORMYCOSIS in persons suffering from other debilitating diseases.Mucormycosis: Infection in humans and animals caused by any fungus in the order Mucorales (e.g., Absidia, Mucor, Rhizopus etc.) There are many clinical types associated with infection of the central nervous system, lung, gastrointestinal tract, skin, orbit and paranasal sinuses. In humans, it usually occurs as an opportunistic infection in patients with a chronic debilitating disease, particularly uncontrolled diabetes, or who are receiving immunosuppressive agents. (From Dorland, 28th ed)Rhizopus: A genus of zygomycetous fungi of the family Mucoraceae, order MUCORALES, a common saprophyte and facultative parasite of mature fruits and vegetables. It may cause cerebral mycoses in diabetes and cutaneous infection in severely burned patients.Zygomycosis: Infection in humans and animals caused by fungi in the class Zygomycetes. It includes MUCORMYCOSIS and entomophthoramycosis. The latter is a tropical infection of subcutaneous tissue or paranasal sinuses caused by fungi in the order Entomophthorales. Phycomycosis, closely related to zygomycosis, describes infection with members of Phycomycetes, an obsolete classification.Absidia: A genus of zygomycetous fungi, family Mucoraceae, order MUCORALES, which sometimes causes infection in humans.Mucor: A genus of zygomycetous fungi of the family Mucoraceae, order Mucorales. It is primarily saprophytic, but may cause MUCORMYCOSIS in man from spores germinating in the lungs.Fungi: A kingdom of eukaryotic, heterotrophic organisms that live parasitically as saprobes, including MUSHROOMS; YEASTS; smuts, molds, etc. They reproduce either sexually or asexually, and have life cycles that range from simple to complex. Filamentous fungi, commonly known as molds, refer to those that grow as multicellular colonies.Mycology: The study of the structure, growth, function, genetics, and reproduction of fungi, and MYCOSES.Antifungal Agents: Substances that destroy fungi by suppressing their ability to grow or reproduce. They differ from FUNGICIDES, INDUSTRIAL because they defend against fungi present in human or animal tissues.Spores, Fungal: Reproductive bodies produced by fungi.TriazolesOpportunistic Infections: An infection caused by an organism which becomes pathogenic under certain conditions, e.g., during immunosuppression.MycosesDNA, Fungal: Deoxyribonucleic acid that makes up the genetic material of fungi.Amphotericin B: Macrolide antifungal antibiotic produced by Streptomyces nodosus obtained from soil of the Orinoco river region of Venezuela.
