Fungi | Disease | Source of Infection | Pathological Manifestations | Diagnosis | Antifungals |
---|---|---|---|---|---|
Endemic | |||||
Blastomyces dermatitidis | Blastomycosis | Soil | Mild flu-like symptoms; chronic cutaneous disease with subcutaneous lesions on the face and hands | Microscopic observation of sputum samples; urine antigen test; enzyme immunoassay | Amphotericin B, ketoconazole |
Coccidioides immitis | Coccidioidomycosis (valley fever) |
Soil | Granulomatous lesions on the face and nose; meningitis in severe cases | Serological tests | Amphotericin B |
Histoplasma capsulatum | Histoplasmosis | Soils with bird or bat droppings | Fever, headache, and weakness with some chest discomfort | Chest X-ray; cultures grown on fungal selective media; direct fluorescence antibody and Giemsa staining | Amphotericin B, ketoconazole, itraconazole |
Paracoccidioides sp. | Paracoccidioidomycosis | Soil near armadillo burrows | Adults: affects lungs and causes lesions in the mouth and throat; Children: swollen lymph nodes and skin lesions |
Chest X-ray, biopsy for fungal culture or to be examined under the microscope and blood tests | Itraconazole and amphotericin B; trimethoprim/sulfamethoxazole |
Talaromyces marneffei (formerly Penicillium marneffei) | Talaromycosis (formerly Penicilliosis) |
Plants and farmed animals | Fever, weight loss, hepatosplenomegaly, lymphadenopathy, skin lesions | Microscopy, histology, and culture | Amphotericin B or voriconazole followed by itraconazole |
Sporothrix schenckii | Sporotrichosis (rose gardener’s disease) |
Soil, Sphagnum moss, rose bushes and hay | Cutaneous nodules that spread and break down into abscesses and ulcers, with rare pulmonary involvement | Culture | Itraconazole, amphotericin B |
Opportunistic | |||||
Aspergillus fumigatus | Aspergillosis | Soils and organic debris | Asthma-like allergic reactions; shortness of breath, wheezing, coughing, runny nose and headaches | Chest X-ray; microscopic examination of tissue and respiratory fluid samples | Itraconazole, voriconazole |
Candida spp. | Candidiasis | Skin and inside the body | Localized or diffuse pneumonia, nodular lesions, abscesses, and empyema | Isolation of the organism from lung tissue samples | Fluconazole (milder cases), amphotericin B deoxycholate, lipid formulations |
Cryptococcus neoformans | Cryptococcosis | Soil, pigeon guano and tropical and subtropical trees | Fever, fatigue, and a dry cough; when spreading to the brain causes meningitis (headaches, sensitivity to light, and confusion) | Microscopic examination of lung tissues or cerebrospinal fluids | Amphotericin B combined with flucytosine followed by fluconazole for up to 6 months |
Nonpigmented fungi (other than Aspergillus and Penicillium or Zygomycetes) * | Hyalohyphomycosis | Soil, water or on decomposing organic debris | Lesions from local cutaneous, subcutaneous, corneal, or nasal mucosal disease to disseminated disease involving multiple organs | Culture isolation and/or PCR | Surgical removal with or without azole antifungal therapy |
Rhizopus spp. and Mucor spp. | Mucormycosis (formerly zygomycosis) |
Throughout the environment | Fever, cough, chest pain, and shortness of breath | Tissue biopsy specimens | Amphotericin B and surgical debridement removal in superficial infections |
Dark melanin-pigmented dematiaceous fungi ** | Phaeohyphomycosis | Soil | Sinusitis, subcutaneous nodules or abscesses, keratitis, lung masses, osteomyelitis, mycotic arthritis, endocarditis, brain abscess, and disseminated infection | Examination using Masson-Fontana staining; culture to identify causative species | Surgery and/or itraconazole |
Pneumocystis jirovecii | Pneumocystis pneumonia (PCP) | Person to person through the air | Fever, cough, and shortness of breath | Microscopic examination of tissue and fluid samples from the lungs | Trimethoprim-sulfamethoxazole combination |
