Abstract
SINCE Werbitzki's1 observations that organic dyes having Ehrlich's orthoquinoid constitution caused disappearance of the kinetoplast in trypanosomes, several workers have, from time to time, reported the occurrence of both spontaneous and chemically induced strains of akinetoplastic T. evansi. Hoare2 has fully discussed the early literature on the subject. Recently, Muhlpfordt3 has published his observations on the effect of trypaflavin on the kinetoplast of various trypanosomes, and has shown that repeated administration of trypaflavin caused the complete disappearance of kinetoplast in T. evansi in 81 days. With other trypanosomes such as T. equiperdum, T. brucei and T. gambiense it took 54, 121 and 122 days, respectively, for the complete disappearance of this organelle.
