Fig 2. Overall Chagas-Flow ATE-IgG2a reactivity at early and late stages of single and dual T. cruzi infections.

Fig 2

(A) Panoramic reactivity profile of sera samples at early stage of single (Triangle, n = 50) and dual (Cross, n = 60) as well as at late stage of single (Square, n = 93) and dual (Asterisk, n = 107) T. cruzi infections. The IgG2a reactivity was evaluated along the titration curve with each target-antigens amastigote (AMA = green), trypomastigote (TRYPO = red) and epimastigote (EPI = yellow) from TcI, TcVI and TcII genotypes of T. cruzi. The results are shown in radar charts and expressed as mean of percentage of positive fluorescent parasites (PPFP). (B) Titration curves at eight serum dilutions (1:500 to 1:64,000) using target-antigens AI, AVI and AII; TI, TVI and TII and EI, EVI and EII were assessed at early and late stages of single and dual T. cruzi infections.
