Absence of kinetoplast DNA in a late antigenic variant of Trypanosoma equiperdum.
We have analysed by several biochemical techniques the DNA components of two antigenic variants isolated from Trypanosoma equiperdum. We did not observe any kinetoplast DNA (kDNA) structures or networks in the late antigen variant BoTat 28. Furthermore, the results of reassociation kinetics of in vitro labelled kDNA show that neither kDNA minicircle sequences nor kDNA maxicircle sequences of BoTat 1, the basic antigen type, can be detected in the total DNA of BoTat 28.
