Scoring system used for classification of sarcoptic mange skin lesions determined by histologic assessment of skin sections from affected chamois.

Feature	Measure	Attributed scores
		Absent (0)	Mild (1)	Moderate (2)	Severe (3)
Crusts	Thicknessa	No crust	<2.5	2.5–3.5	>3.5
Alopecia	Percent of hair follicles containing hairs in histologic section	Normal hair	>55	45–55	<45
Mites	Average counts at 10x HPFb	0	1-2	3–6	>6
Eosinophils	Average counts at 40x HPFc	0-1	2–10	11–20	>20
Lymphocytes	Average counts at 40x HPFc	0	1–15	16–50	>50
Mast cells	Average counts at 40x HPFc	0	1–15	16–40	>40

^aThickness (mm) determined in eight randomly selected microscopic cross sections of skin. ^bCounts of mites in eight randomly selected fields. ^cCell number in eight randomly selected fields. HPF: high-powered field.
