Aspergillosis: Infections with fungi of the genus ASPERGILLUS.Invasive Pulmonary Aspergillosis: Lung infections with the invasive forms of ASPERGILLUS, usually after surgery, transplantation, prolonged NEUTROPENIA or treatment with high-doses of CORTICOSTEROIDS. Invasive pulmonary aspergillosis can progress to CHRONIC NECROTIZING PULMONARY ASPERGILLOSIS or hematogenous spread to other organs.Aspergillosis, Allergic Bronchopulmonary: Hypersensitivity reaction (ALLERGIC REACTION) to fungus ASPERGILLUS in an individual with long-standing BRONCHIAL ASTHMA. It is characterized by pulmonary infiltrates, EOSINOPHILIA, elevated serum IMMUNOGLOBULIN E, and skin reactivity to Aspergillus antigen.Pulmonary Aspergillosis: Infections of the respiratory tract with fungi of the genus ASPERGILLUS.

It occurs naturally via the excision of a copy of the repeating sequence from the chromosome and its extrachromosomal replication in a plasmid, or via the production of an RNA transcript of the entire repeating sequence of ribosomal RNA followed by the reverse transcription of the molecule to produce an additional copy of the original DNA sequence. Laboratory techniques have been introduced for inducing disproportional replication by unequal crossing over, uptake of DNA from lysed cells, or generation of extrachromosomal sequences from rolling circle replication.Aspergillus niger: An imperfect fungus causing smut or black mold of several fruits, vegetables, etc.Azoles: Five membered rings containing a NITROGEN atom.Spores, Fungal: Reproductive bodies produced by fungi.Candidiasis: Infection with a fungus of the genus CANDIDA.

Sphenoid sinus communicates with the posterosuperior part of NASAL CAVITY on the same side.Immunosuppression: Deliberate prevention or diminution of the host's immune response. It may be nonspecific as in the administration of immunosuppressive agents (drugs or radiation) or by lymphocyte depletion or may be specific as in desensitization or the simultaneous administration of antigen and immunosuppressive drugs.Tomography, X-Ray Computed: Tomography using x-ray transmission and a computer algorithm to reconstruct the image.Meningitis, Fungal: Meningitis caused by fungal agents which may occur as OPPORTUNISTIC INFECTIONS or arise in immunocompetent hosts.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.Carbenoxolone: An agent derived from licorice root. It is used for the treatment of digestive tract ulcers, especially in the stomach. Antidiuretic side effects are frequent, but otherwise the drug is low in toxicity.Chemotherapy-Induced Febrile Neutropenia: FEVER accompanied by a significant reduction in NEUTROPHIL count associated with CHEMOTHERAPY.Sensitivity and Specificity: Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives. Specificity is the probability of correctly determining the absence of a condition. (From Last, Dictionary of Epidemiology, 2d ed)Bronchiectasis: Persistent abnormal dilatation of the bronchi.Granulomatous Disease, Chronic: A defect of leukocyte function in which phagocytic cells ingest but fail to digest bacteria, resulting in recurring bacterial infections with granuloma formation. When chronic granulomatous disease is caused by mutations in the CYBB gene, the condition is inherited in an X-linked recessive pattern. When chronic granulomatous disease is caused by CYBA, NCF1, NCF2, or NCF4 gene mutations, the condition is inherited in an autosomal recessive pattern.Rhizopus: A genus of zygomycetous fungi of the family Mucoraceae, order MUCORALES, a common saprophyte and facultative parasite of mature fruits and vegetables.
