Phylogenetic taxonomy of Leishmania (Viannia) braziliensis based on isoenzymatic study of 137 isolates.

abstract：:A distinct 8 kDa calcium-binding protein (CaBP) is preferentially expressed at the cercarial stage during the life-cycle of the schistosome. Available data indicate that this CaBP may be associated with tissue/organ remodelling (involving protein degradation and synthesis of new proteins) during transformation of the ...
