Mange (/ ˈmeɪndʒ /) is a type of skin disease caused by parasitic mites. [1] Because various species of mites also infect plants, birds and reptiles, the term "mange", or colloquially "the mange", suggesting poor condition of the skin and fur due to the infection, is sometimes reserved for pathological mite-infestation of nonhuman mammals.
Phytophotodermatitis, also known as berloque dermatitis, [1] [2] [3] margarita photodermatitis, [4] [5] lime disease [6] or lime phytodermatitis [6] is a cutaneous phototoxic inflammatory reaction resulting from contact with a light-sensitizing botanical agent (such as lime juice) followed by exposure to ultraviolet A (UV-A) light (from the sun, for instance).
Photoprotection is the biochemical process that helps organisms cope with molecular damage caused by sunlight. Plants and other oxygenic phototrophs have developed a suite of photoprotective mechanisms to prevent photoinhibition and oxidative stress caused by excess or fluctuating light conditions. Humans and other animals have also developed ...
Photodermatitis, sometimes referred to as sun poisoning or photoallergy, is a form of allergic contact dermatitis in which the allergen must be activated by light to sensitize the allergic response, and to cause a rash or other systemic effects on subsequent exposure. The second and subsequent exposures produce photoallergic skin conditions ...
Sporothrix schenckii, a fungus that can be found worldwide in the environment, is named for medical student Benjamin Schenck, who in 1896 was the first to isolate it from a human specimen. [1] The species is present in soil as well as in and on living and decomposing plant material such as peat moss. It can infect humans as well as animals and ...
Protozoan infections are parasitic diseases caused by organisms formerly classified in the kingdom Protozoa. These organisms are now classified in the supergroups Excavata, Amoebozoa, Harosa (SAR supergroup), and Archaeplastida. They are usually contracted by either an insect vector or by contact with an infected substance or surface.
The itching is accompanied by red, pimple-like bumps or hives and skin rash or lesions on a sun-exposed area. For humans, itching usually occurs after the larvae detach from the skin. [15] After feeding on their hosts, the larvae drop to the ground and become nymphs, then mature into adults, which have eight legs and are harmless to humans.
Sporotrichosis is caused by fungi of the S. schenckii species complex. [5] [6] Because S. schenckii is naturally found in soil, hay, sphagnum moss, and plants, it most often affects farmers, gardeners, and agricultural workers. [7] It enters through small cuts in the skin to cause a fungal infection. [1]
