Known as feline scabies

Also common ectoparasite of tropical bats

Parasite of cats, rats, man and rabbits

Recognition

Similar to Sarcoptes

Less distinct angles on body surface

Females have suckers on legs 1 and 2

Females are about 225μm in length and males 150μm

Anal opening is distinctly dorsal (not posterior)

Pathogenesis

Infection begins on the ear tips and spreads over the body

Notoedres cati in notoedric skin infestation

Causes dermatitis

Burrowing of females damages keratinocytes leading to cytokine release

Hypersensitivity reaction may occur

Diagnosis

Superficial skin scraping

A single nest in a scraping may yield many mites

-==Introduction==
+*Also common ectoparasite of tropical bats
-''Notoedres'' are [[Burrowing Mites|burrowing mites]] of cats, rats, man and rabbits. They are also common ectoparasites of tropical bats.
-==Identification==
+*Parasite of cats, rats, man and rabbits
-The Notoedres mite is similar to [[Sarcoptes]] although it has less distinct angles on its body surface. The female mites have suckers on legs 1 and 2 and are about 225μm in length. Males are 150μm in length. The anal opening of the Notoedres is distinctly dorsal, not posterior.
-==Lifecycle==
+'''Recognition'''
+*Similar to ''Sarcoptes''
-The entire life cycle takes place on a single host and takes between 14 and 21 days to complete. The female mite burrows into the skin and lays eggs in the created tunnels. After the female deposits the eggs, she dies.
+*Less distinct angles on body surface
-'''Eggs'''<br/>
+*Females have suckers on legs 1 and 2
-Laid into the stratum corneum by the burrowing female.<br/>
-'''Larvae'''<br/>
-Burrow into the skin and go through two nymphal stages before reaching maturity.
-==Diagnosis==
+*Females are about 225μm in length and males 150μm
-The method of detection for Notoedres is usually via a superficial skin scraping. A single nest in a scraping may yield many mites.
+*Anal opening is distinctly dorsal (not posterior)
-==Important Species==
-''Notoedres cati''- This species causes [[Feline Scabies|feline scabies]], an example of a notoedric skin infestation.
