The hyphae of Aspergillus species range in diameter from 2.5 to 4.5 μm. They have septate hyphae, [28] but these are not always apparent, and in such cases they may be mistaken for Zygomycota. [27] Aspergillus hyphae tend to have dichotomous branching that is progressive and primarily at acute angles of around 45°. [27]
Aspiration pneumonia; Microscopic image of aspiration pneumonia in an elderly person with a neurologic illness. Note foreign-body giant cell reaction. Specialty: Emergency medicine, pulmonology: Symptoms: Fever, cough [1] Complications: Lung abscess and pneumonia [1] Usual onset: Elderly [2] Risk factors
Viewing the fungi under a microscope, Micheli was reminded of the shape of an aspergillum (holy water sprinkler), from Latin spargere (to sprinkle), and named the genus accordingly. [2] [3] Aspergillum is an asexual spore-forming structure common to all Aspergillus species; around one-third of species are also known to have a sexual stage. [4]
[1] [7] Systemic fungal infections are more serious and include cryptococcosis, histoplasmosis, pneumocystis pneumonia, aspergillosis and mucormycosis. [3] Signs and symptoms range widely. [3] There is usually a rash with superficial infection. [2] Fungal infection within the skin or under the skin may present with a lump and skin changes. [3]
Fungal pneumonia is an infection of the lungs by fungi. It can be caused by either endemic or opportunistic fungi or a combination of both. Case mortality in fungal pneumonias can be as high as 90% in immunocompromised patients, [ 1 ] [ 2 ] though immunocompetent patients generally respond well to anti-fungal therapy.
Chronic pulmonary aspergillosis is a long-term fungal infection caused by members of the genus Aspergillus—most commonly Aspergillus fumigatus. [8] The term describes several disease presentations with considerable overlap, ranging from an aspergilloma [12] —a clump of Aspergillus mold in the lungs—through to a subacute, invasive form known as chronic necrotizing pulmonary aspergillosis ...
Aspergillus candidus is a member of the genus Aspergillus in the family Trichocomaceae, phylum Ascomycota. [8] [9] A number of subspecies and varieties have been recognised including: A. candidus subsp. tjibodensis, A. candidus var. amylolyticus, A. candidus var. candidus, A. candidus var. densior, and A. candidus var. tenuissima.
This species is second in prevalence after Aspergillus fumigatus as a fungal pathogen in cystic fibrosis patients. It causes allergic bronchopulmonary disease and chronic lung lesions that resemble aspergillosis. [15] Infections can also occur in immunocompetent individuals, usually in the lungs and upper respiratory tract. [10]
