Abstract:
:The fatty acid composition during the transformation of Trypanosoma cruzi epimastigotes into metacyclic trypomastigotes (metacyclogenesis) was analysed by gas-liquid chromatography and mass spectrometry. Significant qualitative and quantitative changes in the fatty acid composition occurred during incubation of epimastigotes derived from LIT medium in the triatomine artificial urine (TAU). Metacyclogenesis was also followed by alterations in the fatty acid pattern but these were considerably less pronounced when compared to the pattern obtained for TAU-incubated epimastigotes. These results suggest that changes in the lipid composition precede the morphological transformation of epimastigotes into metacyclic trypomastigotes.
