Absence or Presence of PGL-I in the Lesional Skin of Leprosy Patients (n = 41; BI: 0–1+) Combined with the Presence or Absence of High Anti-PGL-I Antibody Titer (OD >0.500) in the Corresponding Serum

Number of patients	In situ PGL-I*	High anti-PGL-I antibody titer in serum†
12	+	+
18	−	−
8	+	−

*In situ presence of PGL-I was determined by immunohistochemical analysis using MAb DZ-1.

^†Anti-PGL-I antibodies in serum were determined by ELISA. Serum values were considered high when OD was >0.500.
