Comparison of baseline expression levels among studied isolates.

<p>(A) Gene expression analysis among <u>promastigotes</u>: PRO constant term, measure of the baseline expression of a given gene in the promastigote stage (highlighted in black if significantly higher –by at least 2-fold– than the lowest constant term in the series). (B) Gene expression analysis among <u>amastigotes</u>: AMA constant term, measure of the baseline expression of a given gene in the amastigote stage (highlighted in black if significantly different –by at least 2-fold– from the lowest constant term in the series).
