	==Overview==		==Overview==
	Knemidocoptes are [[Burrowing Mites\|burrowing mites]] of avian species. There are a number of important species infecting both production birds and pet animals. The mites tend to infect unfeathered areas of birds and so commonly cause scale as a clinical sign. Spread of these mites occurs from prolonged close contact between birds, such as occurs between a mother and unfeathered young.		''Knemidocoptes'' are [[Burrowing Mites\|burrowing mites]] of avian species. There are a number of important species infecting both production birds and pet animals. The mites tend to infect unfeathered areas of birds and so commonly cause scale as a clinical sign. Spread of these mites occurs from prolonged close contact between birds, such as occurs between a mother and unfeathered young.

			''Knemidocoptes'' is the ''' only''' genus of burrowing mite found in birds. There are three main species of Knemidocoptes that affect birds and these are ''K. mutans, K. gallinae'' and ''K. pilae'', which all cause different disease manifestations and clinical signs.


	==Identification==		==Identification==
	''Knemidocoptes'' are small round mites found in different locations on avian species dependent on the species of mite present. They have a stumpy legged appearance as their coxa are sunk into the body. Unlike other burrowing mites, that have pediculated suckers, the tarsal portions of ''Knemidocoptes'' mites have claw like structures and tactile hairs. They may look similar to ''[[Sarcoptes]] spp.'' however they lack pegs and have dorsal striations instead. The mites breath through their cuticles and therefore are astigmata. The presence of a terminal anus can also be used as a distinguishing feature.		''Knemidocoptes'' are small round mites found in different locations on avian species dependent on the species of mite present. They have a stumpy legged appearance as their coxa are sunk into the body and a U-shaped chitinous bar found behind the head.

			Unlike other burrowing mites, that have pediculated suckers, the tarsal portions of ''Knemidocoptes'' mites have claw like structures and tactile hairs. They may look similar to ''[[Sarcoptes]] spp.'' however they lack pegs and have dorsal striations instead. The mites breath through their cuticles and therefore are astigmata. The presence of a terminal anus can also be used as a distinguishing feature.

	~~==Detection==~~
	The method of detection is a combination of the presence of clinical signs as well as identification of mites on a skin scrape or feather pluck. Not all infections of ''Knemidocoptes'' mite result in clinical signs, some may lay dormant for until the animal is stressed or is otherwise immunocompromised.

	==Life Cycle==		==Life Cycle==
Line 32:		Line 34:
	''Knemidocoptes'' mites have hexapod larvae. They burrow into the skin creating moulting pockets and undergo two nymphal stages before reaching maturity.

	~~==Important Species==~~
	*''K. mutans''
	::This species is the cause of '''scaly leg''' in poultry species as the mite burrows beneath scales on the leg and foot. This causes lameness as well as the presence of ragged legs and feed and distorted claws.

	*''K. gallinae''		== Clinical Signs ==
	:~~:This species is a depluming itch mite in poultry. The mite burrows into feather shafts and causes pain and pruritus causing birds to pull out their own body feathers.~~		Signs are dependent on which mite is present:

	*''K. ~~pilae~~''		===''K. gallinae''===
	~~::This species~~ is the cause of '''scaly face''' psittacine birds~~. The mite attacks~~ the ~~bare~~ areas of the face~~, beak, cere~~ and body ~~causing~~ scaliness but ~~little pruritus~~.
			The disease associated with this mite is called '''depluming itch'''. Mites burrow into the feather shafts and cause intense pruritus and pain, so much so that the bird will pull out its feathers. Therefore clinical signs include loss of feathers by self trauma, depression, intense pre-occupation in pulling out feathers. The bird will often not eat and will appear to lose weight.


			===''K. mutans''===

			The disease caused by this mite is called '''scaly leg'''. This specie of mite burrows beneath leg scales and causes them to loosen and rise. Clinical signs will include the bird having distorted legs and claws and may appear lame. The bird may also be paying particular attention to their legs and may show signs of pruritus.


			===''K. pilae''===

			The disease associated with this mite is called '''scaly beak''' ('''scaly face''' in psittacine birds) and is caused when the mites burrow into feathered parts of the beak and into the lightly feathered areas of the face and body. Clinical signs will include loss of feathers and scaliness around the base of the beak and spreading over the face. There may be mild pruritus but not as severe as other forms in the genus.

			Not all infections of ''Knemidocoptes'' mite result in clinical signs, some may lay dormant for until the animal is stressed or is otherwise immunocompromised.


			== Diagnosis ==
			History and clinical signs are very suggestive of the disease. A deep skin scraping is required to identify the mites and this should be performed by scraping the skin until capillary blood is seen. Feather pluck may also prove useful.


			== Treatment and Control ==

			There are few licensed [[Ectoparasiticides\|acaracidal]] treatments for poultry. Repeated treatment with one of the licensed treatments is necessary to cure this disease. Prophylactic acaracidal treatment can be used for prevention.

	~~===Treatment===~~
	~~Treatment requires repeated use of [[Ectoparasiticides\|acaricides]] however there are few of these products licensed for use in poultry.~~
