Toxoplasma gondii-specific IgG antibodies in Swedish reindeer samples (n = 528), expressed as sample to positive ratio percentage (S/P%) (y-axis). Serum samples were considered to test positive at S/P% ≥ 50% (solid line), inconclusive at S/P% values between ≥ 40% (dotted line) and < 50%, and negative at S/P% < 40%
