State the characteristic features of Coprophilous Fungi ?
Answers
Coprophilous fungi also known as Panaeolus semiovatus var, is responsible for the disorder in the respiratory system. It generally grows in marshy lands and on animal dungs.
The are generally of light golden in colour and with a inverse bowl like-shape in the top, quite similar to the mashroom. They are popularly known as dung fungi because the grazing animals act as the vector of this fungi by eating their spores and help in reproduction. Even the name 'Coprophilous fungi' is derived from the Greek word 'Coprophilous' which means 'dung'.
The mycelium of Coprophilous fungus is found in the vegetative part of the fungi-body. They are consisted of a branch of hyphae, which is thread like in shape. The fungal colonies are generally found in the soil.
Coprophilous fungi are considered as one of the most ideal organism for the purposes of teaching biodiversity and also for teaching an researching in ecology, for example, Pilobolus, which is one the 175 genera, found in dung.
Answer:
Many fungi isolated from vertebrate animals are neither commensals nor pathogens. They are contaminants, pathologically insignificant organisms of external origin, often isolated from environmentally exposed materials such as lung tissue or other parts of the respiratory tract, the gut, and the skin. Categories of association (commensalism, pathogenicity, contamination) overlap to some extent because a commensal or ordinarily harmless environmental fungus may become pathogenic with changes in the immunological or ecological status of the animal host. Isolation of an associated fungus is often easier than the correct evaluation of its status.
