摘要

Expression of TSA 417, the predominant cysteine-rich variable surface protein of Giardia lamblia WB clone C6 trophozoites, did not change during encystation in vitro. However, in vitro excystation of cysts derived in vitro or in vivo consistently produced TSA 417 nonexpressing trophozoite populations, suggesting that completion of the life cycle leads to antigenic switching.
