Studies on mitochondrial ATPase of Leishmania donovani using digitonin-permeabilized promastigotes.

abstract：:The karyotype and chromosomes of the human malaria parasite Plasmodium falciparum have been well characterized in recent years. Here we present karyotype maps of the three other human malaria species, P. vivax, P. malariae and P. ovale. Chromosomes of these species were found to be of significantly higher molecular we...
