We investigated the occurrence of antigenic and biochemical variability among Paracoccidioides brasiliensis antigen batches prepared according to the same protocol. Initially (experiment 1), we analyzed two antigen lots ...

Giardia lamblia trophozoites undergo antigenic variation, whereone member of the Variant-specific Surface Protein (VSP)family is expressed on the surface of proliferating trophozoitesand periodically replaced by another ...

Giardia lamblia is a human intestinal pathogen. Like many protozoan microorganisms, Giardia undergoes antigenic variation, a mechanism assumed to allow parasites to evade the host's immune response, producing chronic and/or ...
