Abstract

Transformation ofTrypanosoma brucei bloodstream forms to procyclic forms can be stimulated in vitro by adding 2–10 mM citrate and/or cis-aconitate to the culture medium for at least 3 h. Optimal transformation was obtained in the presence of 3 mM cis-aconitate for 48 h. Citrate and cis-aconitate may activate isocitrate dehydrogenase and/or other Krebs' cycle enzymes and thus act as a metabolic trigger for the morphological changes involved in transformation.
