Figure 2.

Immunoelectrotransfer of somatic antigens separated by sodium dodecyl sulfate–polyacrylamide gel electrophoresis against serum samples from A, 16 patients with gnathostomiasis (arrows indicate specific protein bands); B, 2 patients infected with Strongyloides stercoralis; and C, 5 healthy persons (arrow indicates the protein with 100% cross-reactivity). D, Positive and negative results according to molecular weight (MW). Asterisks indicate specific peptides and the dotted line indicates the minimum value for considering a result specific for gnathostomiasis. kDa = kilodaltons.
