Stress response to high osmolarity in Trypanosoma cruzi epimastigotes.

Trypanosoma cruzi undergoes differentiation in the rectum of triatomine, where increased osmolarity is caused mainly by elevated content of NaCl from urine. Early biochemical events in response to high osmolarity in this parasite have not been totally elucidated. In order to clarify the relationship between these events and developmental stages of T.
