SEM of the fungus Alternaria alternata
Bildnummer 11525280
| Scanning electron micrograph (SEM) of the fungus Alternaria alternata,a causative agent of respiratory allergies. Here,fungal threads of the vegetative mycelium are seen,each thread is called a hypha,with a spore-producing fruiting body at centre right. Large amounts of spores are produced by this fungus,leading to its allergic properties. Alternaria alternata is a cause of both allergic rhinitis (hay fever) in which inflammation of the mucous membrane of the nose occurs; and of allergic asthma. Asthma is the more serious condition,affecting the lungs. Repeated inhaling of fungal spores may cause hypersensitivity reactions. Magnification: x685 at 6x7cm size | |
