Western blotting profile of crude soluble antigens of L. donovani promastigotes hybridized with sera from different groups. Shown in each panel are sera from patients with parasitologically confirmed VL before (D 0) and after (D 30) treatment and at the 6-month follow-up visit (D 180), healthy controls not from an area of endemicity (HC), and healthy controls from an area of endemicity (EC). Arrows indicate the BHUP2 protein, which was recognized by the sera of VL patients pre- and posttreatment but not by the sera of our control groups.
