This disease page is currently being used in Wildpro to link different data types and demonstrate inter-relationships. Whilst basic information is available, it does not contain comprehensive information.
See also other mite infections:
- Chorioptes sp. mites. These mites live on the surface and feed only superficially, on shed scales of skin and other debris. (B24, B46)
- N.B. It has been suggested that Chorioptes sp. mange may be diagnosed in hedgehogs which have Caparinia sp. mange (See: Caparinia Mange in Hedgehogs).(J204.59.w1)
- Chorioptes sp. - Psoroptidae (Family)
Clinical Signs
Chorioptic mange is associated with pruritic scaly lesions. The area of the body affected varies depending on the host: in horses the legs (below the knees and hocks); in cattle, wild ruminants and camels often the tail root, spreading if untreated to the sacral area and other areas (may affect the neck, tail-head, udder and legs); in sheep on the lags and (in rams) the scrotum). (B24, B46)
In Hedgehogs:
- "Chorioptes spp. have been isolated from the skin of the hedgehog." (B16.13.w13)
- Clinical signs reported of crusty skin lesions, particularly on the ears, but with little scratching by the hedgehog. (B16.13.w13)
- Loss of quills/hairs, skin thickening and scaling. Lesions most prominent on the lateral muzzle and on the ear tips. No apparent pruritus. (J2.19.w1)
In Bears:
- In Ursus maritimus - Polar bear
at Rostock Zoo, hair and skin problems, worse in winter, with
behaviour suggesting severe pruritus. From just behind the ears all
the way to the base of the tail, a broad strip where the hair was thin
and in areas the skin was hairless, or hair was broken. Sometimes the
shoulders and upper parts of the forelimbs were affected and rarely
the hindlegs were also affected. On the sides, lesions were
bilaterally symmetrical. Where the bears were alopecic, they looked
dirty and grey due to the black skin showing, while where more hair remained it looked dirty red-yellow. When the bears bathed, they
looked black. (P5.28.w2)
- Histological examination of skin biopsies showed dermatitis with secondary complications, including hyperaemia, hyperplasia and hypertrophy, crusts erosions, pustules, ulcerations and excoriations. Choriotes sp. mites were eventually detected in biopsies. (P5.28.w2)
In Bears:
- Chorioptic mites were found at necropsy of an Ursus arctos - Brown bear cub at Rostock zoo. (P5.29.w5)
Diagnosis:
- Diagnosis of chorioptic mange is by examination of skin scrapings. (B24)
- In Hedgehogs:
- In Bears:
- Mites were eventually isolated from skin biopsies and identified as Chorioptes sp. (P5.28.w2)
Differential Diagnosis:
- In Hedgehogs: N.B. It has been suggested that Chorioptes sp. mange may be diagnosed in hedgehogs which have Caparinia sp. mange (See: Caparinia Mange in Hedgehogs).(J204.59.w1)
- In Bears: Other mite infections, dermatophilosis, ringworm and vitamin A deficiency. See:
Treatment:
- Washing with a suitable acaricide (scrubbed onto lesions). (B46)
- In Hedgehogs:
- Clinical disease reduced by ivermectin, 0.2 mg/kg intramuscular every 21 days. (J2.19.w1)
- Skin infection, but not ear infection, in Atelerix albiventris - Four-toed hedgehog was eliminated by Amitraz, 0.03%, two washes (by spraying from an atomiser bottle) seven days apart. (J2.19.w1)
- In Bears:
- Ivermectin by subcutaneous injection [dose not stated]; this resulted in a decrease in clinical signs. (P5.28.w2)

- Chorioptic mange (Chorioptes sp. infection) was diagnosed in an adult male Atelerix albiventris - Four-toed hedgehog in Canada. (J14.41.w1)
- Chorioptes sp. identified in skin scrapes from a group of Atelerix albiventris - Four-toed hedgehog with mange lesions in a zoo. (J2.19.w1)
