Ferret, Rabbit and Rodent Dermatology Flashcards
What disease are ferrets prone to and why?
Adrenal disease b/c they are spayed/neutered at a very young age
- early spay/neuter inhibits sex hormone production (by the testicles, uterus -> over-functioning of the adrenal glands to produce these missing sex hormones
sex hormones: estrogens, androgens, progestagens
Clinical signs of Ferret Adrenal Disease
alopecia, pruritis, swollen vulva, stranguria of prostate gland, behavioral changes
What ectoparasites are ferrets susceptible to?
Fleas, ear mites, warbles (cuterebra larva)
Sarcoptic mites = rare in U.S.
Demodectic mites = immunosuppressed ferrets
Chordoma
- Thought to develop from intraosseous remnants of the fetal notochord
- Occur @ tip of tail
Malignant skin tumor in ferrets
Cutaneous lymphosarcoma
Common skin disorders in rabbits
- Cheyletiella fur mties (patchy alopecia)
- Fleas (tx = revolution or advantage)
- myiasis (cuterebra - outdoor exposure)
- moist dermatitis (“slobbers” – pseudomonas aeruginosa)
- SC facial abscesses (dental disease)
- ulcerative pododermatitis (poor husbandry)
pododermatitis = inflammation of foot/paw
What can cause alopecia without dermatitis in Guinea Pigs?
Ovarian cysts
What nutritional condition are guinea pigs susceptible to? Clinical sign?
Scurvy (vitamin C deficiency) -> scaling of pinna; rough hair coat; white, crusty discharge around the eyes
What causes dermatophytosis in ferrets, rabbits and rodents?
Trichophyton mentagrophytes; is zoonotic!
- patches/focal areas of alopecia
Rabbit Venereal Spirochetosis (“Rabbit Syphillis”)
- transmission
- lesion locations
- clincal signs
RABBIT STD
- transmitted via sexual contact or at birth
- lesion locations = external genitalia and the face
- signs: hyperemia and edema -> macules, papules, erosions ulcers, crusts
