Ornithonyssus is a mite genus of the family Macronyssidae.
The Acaridae are a family of mites. Common forms include some mold mites, for example the grain mite. Genera in the family include:
Dermanyssus gallinae is a haematophagous ectoparasite of poultry. It has been implicated as a vector of several major pathogenic diseases. Despite its common names, it has a wide range of hosts including several species of wild birds and mammals, including humans. In both size and appearance, it resembles the northern fowl mite, Ornithonyssus sylviarum.
Mesostigmata is an order of mites belonging to the Parasitiformes. Unlike most members of that group, many of these mites are not parasitic but free-living and predatory. They can be recognized by the single pair of spiracles positioned laterally on the body.
Amblyseius is a large genus of predatory mites belonging to the family Phytoseiidae. Many members of this genus feed on other mites such as red spider mites, and also on thrips. Several species are popular as biological control agents to control these pests.
The Holothyrida are a small order of mites in the superorder Parasitiformes. No fossils are known. With body lengths of more than 2 mm they are relatively large mites, with a heavily sclerotized body. They mainly feed on the body fluids of dead arthropods. This was possibly the common way of feeding for ticks before they adapted for feeding on the blood of live animals.
Histiostomatidae is a family of astigmatid mites and branches basically in a phylogenetic tree of the Astigmata.
Human parasites include various protozoa and worms that may infect humans that cause parasitic diseases.
Gamasoidosis or dermanyssosis is a frequently unrecognized ectoparasitosis and source of growing concern in human medicine, occurring after contact with avian mites which infest canaries, sparrows, starlings, pigeons and poultry and caused by two genera of mites, Ornithonyssus and Dermanyssus. Avian mite species implicated include the red mite, tropical fowl mite and northern fowl mite . Mite dermatitis is also associated with rodents infested with the tropical rat mite, spiny rat mite and house-mouse mite, where the condition is known as rodent mite dermatitis. Urban gamasoidosis is associated with window-sills, ventilation and air-conditioning intakes, rooves and eaves, which serve as shelters for nesting birds. Humans bitten by these mites experience a non-specific dermatitis with intense itching.
Ornithonyssus bacoti is a hematophagous parasite. It feeds on blood and serum from many hosts. O. bacoti can be found and cause disease on rats and wild rodents most commonly, but also small mammals and humans when other hosts are scarce. Outbreaks tend to occur in older, less maintained buildings. The mite, however, can travel several hundred feet on its own if necessary to find a host and can survive for extended periods of time without a host. This, along with the nonspecific dermatitis it causes, can prevent accurate and fast diagnosis of rat mite dermatitis. The scarcity of reports, due in part to misdiagnosis and also the mildness of its symptoms, makes the disease seem less common than it is. The tropical rat mite can be found in both temperate and tropical regions or rather all continents except the Arctic and Antarctic.
Dermanyssus is a genus of mites in the family Dermanyssidae. The etymology of the word Dermanyssus is from the Greek: derma, meaning skin, and nyssein, meaning bite.
Androlaelaps is a genus of mites in the family Laelapidae.
The Macronyssidae are a family of parasitic mites in the order Mesostigmata.
The Laelapidae are a family of mites in the order Mesostigmata. The family is also referred to in the literature as Laelaptidae, which may be the correct spelling.
Dermanyssidae is a family of mites in the order Mesostigmata.
Ornithonyssus bursa is a species of mite. It is most often a parasite of birds, but also has been found to bite humans and two species of mammals. It usually lives in birds' feathers, but for laying its eggs, it more often uses their nests rather than their feathers. Tropical fowl mites undergo five stages during their development: egg, larva, protonymph, deutonymph, and adult. During the last two stages, they suck blood from their host for food. They are often diurnal, whereas northern fowl mites are nocturnal in nature.
Ornithonyssus sylviarum is a haematophagous ectoparasite of poultry. In both size and appearance, it resembles the red mite, Dermanyssus gallinae.
Haemogamasus is a genus of mites in the family Haemogamasidae. In North America, they mostly infect rodents, in addition to other small mammals such as shrews, talpids, and Virginia opossums.
Ameroseiidae is a family of mites in the order Mesostigmata.
Rhinonyssidae is a family of mites in the order Mesostigmata.
Mites are small crawling animals related to ticks and spiders. Most mites are free-living and harmless. Other mites are parasitic, and those that infest livestock animals cause many diseases that are widespread, reduce production and profit for farmers, and are expensive to control.
