The rust is distinguished by the typical rust-like marks on the stem and leaves, causing defoliation and loss of photosynthetic surface along with reduction in yield. The disease is fungal and is autoecious meaning it has one plant host. The rust of faba beans is macrocyclic, or contains 5 spores during its life cycle.
Rust fungi grow intracellularly, and make spore-producing fruiting bodies within or, more often, on the surfaces of affected plant parts. [3] Some rust species form perennial systemic infections that may cause plant deformities such as growth retardation, witch's broom, stem canker, galls, or hypertrophy of affected plant parts.
Human interactions with fungi include both beneficial uses, whether practical or symbolic, and harmful interactions such as when fungi damage crops, timber, food, or are pathogenic to animals. Yeasts have been used since ancient times to leaven bread and to ferment beer and wine .
In humans, oral candidiasis is the most common form of candidiasis, [17] by far the most common fungal infection of the mouth, [5] and it also represents the most common opportunistic oral infection in humans [40] with lesions only occurring when the environment favors pathogenic behavior.
The genus is the second-largest plant pathogenic rust genus, which is responsible for various plant affecting diseases, and it has major effects on both agricultural and non-agricultural plants. The genus is generally characterized by its unicellular teliospores (thick-walled resting spores) that help to characterize it and distinguish it from ...
Bean rust is a disease of the green bean that causes rust-colored pustules on the leaves. These pustules eventually rupture and eject thousands of spores into the air to be carried to other plants. [64] Each individual spore can produce a fresh pustule on a plant within a week; therefore untreated rust can rapidly reach epidemic levels. [64]

The environment present in the human mouth allows the growth of characteristic microorganisms found there. It provides a source of water and nutrients, as well as a moderate temperature. [ 2 ] Resident microbes of the mouth adhere to the teeth and gums to resist mechanical flushing from the mouth to stomach where acid-sensitive microbes are ...
