FIG. 2.

Disease parameters for EIAV lipopeptide-immunized (a) and control lipopeptide-immunized (b) horses following EIAV challenge. Morning rectal temperatures (in °F) are on the left scale (closed squares) and periodic platelet counts × 1,000 per μl blood are on the right scale (open circles). Rectal temperatures above the dark solid horizontal line were considered fevers, and platelet counts below the lighter dotted horizontal line were considered thrombocytopenic.
