If nothing fluoresces, use the “sterile toothbrush” technique! “Comb” pet with toothbrush to collect hair/scales used to inoculate media.

Primary is the initial spontaneous lesions that reflect the underlysing disease; often appear & disappear quickly
Secondary evolve from primary lesions or are induced by patient or external factors; often what we or owners see
What are the Secondary Lesions?
Epidermal collarette
Lichenification
Scar
Excoriation
Erosion
Ulcer
Fissure
Callus
Name this lesion!
Cyst
Explain how to do a superficial skin scrape.
Moisten a dulled scalpel blade with liquid paraffin or KOH or mineral oil.
Scrape a larger area because mites are fewer in number
Name this lesion!
Nodule

What are the indications for doing a skin biopsy (6)?
Nodules/tumors
Ulcer/vesicles
Severe acute generalized disease
Mucosal lesions
Lesions unresponsive to rational treatment
Name this lesion!
Lichenification
Name this lesion!
Vesicle
True or False: After performing a deep skin scrape you do not see any demodex mites. You tell the client that even though you did not see any does not mean they do not have any mites.
True!
If negative, may not rule out follicular parasites
*scrape multiple areas to help with accuracy
