A high level of mixed Trypanosoma brucei infections in tsetse flies detected by three hypervariable minisatellites.

abstract：:We have characterised the organisation of genes encoding the glutamate and alanine rich protein (GARP) surface coat of the procyclic and epimastigote stages of Trypanosoma congolense in the tsetse fly. The GARP genes are arranged at two, possibly physically linked, loci, one of which exhibits allelic variation. One lo...

We now show that chloroquine binds more avidly to poly(dG-dC).poly(dG-dC) than to other synthetic polynucleotides and that this binding inhibits both salt- and cobalt-induced transitions to Z-DNA. These data are consistent ...
