Demodex / ˈ d ɛ m ə d ɛ k s / is a genus of tiny mites that live in or near hair follicles of mammals.Around 65 species of Demodex are known. [2] Two species live on humans: Demodex folliculorum and Demodex brevis, both frequently referred to as eyelash mites, alternatively face mites or skin mites.
Gongylonema pulchrum was first named and presented with its own species by Molin in 1857. The first reported case was in 1850 by Dr. Joseph Leidy, when he identified a worm "obtained from the mouth of a child" from the Philadelphia Academy (however, an earlier case may have been treated in patient Elizabeth Livingstone in the seventeenth century [2]).
Demodex folliculorum is a microscopic mite that can survive only on the skin of humans. [2] [3] Most people have D. folliculorum on their skin.Usually, the mites do not cause any harm, so are considered an example of commensalism rather than parasitism; [4] but they can cause disease, known as demodicosis.
Symptoms to note: Bed bug bites aren’t too painful, but they can be very itchy and swollen. The parasites don’t spread diseases like ticks do; however, they’re difficult to remove and won ...
Pediculosis pubis (also known as "crabs" and "pubic lice") is an infestation by the pubic louse, Pthirus pubis, a wingless insect which feeds on blood and lays its eggs (nits) on mainly pubic hair.
Whole blood with microfilaria worm, giemsa stain. L. loa worms have a simple structure consisting of a head (which lacks lips), a body, and a blunt tail. The outer body of the worm is composed of a cuticle with three main layers made up of collagen and other compounds which aid in protecting the nematodes while they are inside the digestive system of their host.
Benznidazole and nifurtimox often cause side effects, including skin disorders, digestive system irritation, and neurological symptoms, which can result in treatment being discontinued. [ 2 ] [ 8 ] New drugs for Chagas disease are under development, [ 9 ] and while experimental vaccines have been studied in animal models, [ 10 ] [ 11 ] a human ...
Adults live in the subcutaneous tissues of humans, where they mate and produce wormlike eggs called microfilariae. These microfilariae are 250–300 μm long, 6–8 μm wide, and can be distinguished morphologically from other filariae, as they are sheathed and contain body nuclei that extend to the tip of the tail.
