IFAT+++: 1280–2560 (IgG). IFAT++: 320–640 (IgG). IFAT+: 80–160 (IgG). IFAT−: negative reaction. LST: Leishmanin skin test (= DTH). LST++++: exacerbate reaction (≥16 mm). LST+++: strong reaction (13–15 mm). LST++: moderate reaction (9–12 mm). LST+: weak reaction (5–8 mm). LST−: negative reaction. AI: asymptomatic infection. SI: symptomatic infection (= AVL).
