The diagram Mite infestation sites on skin shows where typical infestations of different taxonomic groups mites on livestock animals occur on or in the host's skin. [9] The position of these mites in relation to the skin or other organs is crucial for their feeding and also for their veterinary diagnosis and options for treatment.
Sarcoptes is a genus of skin parasites, and part of the larger family of mites collectively known as "scab mites". They are also related to the scab mite Psoroptes, also a mite that infests the skin of domestic animals. Sarcoptic mange affects domestic animals and similar infestations in domestic fowls cause the disease known as "scaly leg".
The microscopic mite Lorryia formosa (). The mites are not a defined taxon, but is used for two distinct groups of arachnids, the Acariformes and the Parasitiformes.The phylogeny of the Acari has been relatively little studied, but molecular information from ribosomal DNA is being extensively used to understand relationships between groups.
Aceria guerreronis, the coconut mite, is an eriophyid mite which infests coconut plantations. [1] It is economically devastating, and can destroy up to 60% of coconut production. The immature nuts are infested and injured by mites feeding in the portion covered by the perianth of the immature nut.
A diagram of the stylostome, or the hardened tube of dead cells formed by the larval form of the Trombiculidae when feeding. Chiggers attach to the host, pierce the skin, inject enzymes into the bite wound that digest cellular contents, [ 23 ] and then suck up the digested tissue through a tube formed by hardened skin cells called a stylostome ...
Dermanyssus gallinae (also known as the red mite) is a haematophagous ectoparasite of poultry.It has been implicated as a vector of several major pathogenic diseases. [1] [2] Despite its common names, it has a wide range of hosts including several species of wild birds and mammals, including humans, where the condition it causes is called gamasoidosis.
The individual mites remain external to the epidermis within the follicle, but appear to be within the skin because they are below the general outer surface of the host. The mite Demodex canis is a common cause of demodicosis in dogs. Demodex mites are microscopic, cigar-shaped and have very short legs. These mites seem to feed on epidermal cells.
Three species of mite are a threat to honey bees and one of these, Varroa destructor, has become the largest single problem faced by beekeepers worldwide. [117] Mites cause several forms of allergic diseases, including hay fever , asthma and eczema , and they aggravate atopic dermatitis . [ 118 ]
