Comparing normalised optical densities (OD) from from sera evaluated for TcHSP-70T and TrHSP-70 recombinant proteins. The ELISA for the TcHSP-70T recombinant protein was performed with sera diluted 1/50 and 1/100 for the TrHSP-70 antigen. Data was normalised by subtracting the mean OD of the healthy group for each protein and, when mean OD obtained was lower than 0, it was fixed as 0.
