The Leishmania HSP20 Is Antigenic during Natural Infections, but, as DNA Vaccine, It does not Protect BALB/c Mice against Experimental L. amazonensis Infection
Figure 4
Antigenicity of Leishmania HSP20 in VL human patients and dogs. (a) Reactivity of 16 serum samples
from VL dogs against total L. infantum proteins
(LAg) or L. amazonensis recombinant HSP20 (rHSP20). (b) Reactivity of 12 sera from patients with VL against LAg or rHSP20. Horizontal lines represents the cut-off value of negative sera for the LAg antigen (0.122 for canine sera and 0.232 for human sera). All sera were tested in duplicate at a 1 : 200 dilution.
