Antigenicity of TcG1, TcG2 and TcG4 in inhabitants of Salta Argentina.

<p>Sera (A–C) and plasma (D–I) samples obtained in year 2010 (A–F) and year 2009 (G–I) from volunteers in Salta Argentina were identified as seropositive (+ve) or seronegative (−ve) in 1^st-phase screening by using conventional approaches. The 2^nd-phase screening for antigen-specific antibody response was conducted by an ELISA using the recombinant TcG1, TcG2 and TcG4 proteins. Data (mean of four observations from each sample) are presented as box plot. The horizontal lines of the box (bottom to top) depict the lower quartile (Q1, cuts off lowest 25% of the data), median (Q2, middle value), and upper quartile (Q3, cuts off the highest 25% of the data). The lower and upper whiskers depict the smallest and largest non-outlier observations, respectively, and solid dots represent the outliers. The spacing between the different parts of the box indicates the degree of dispersion (spread). Standard deviation for all samples was <12%.
