Abstract
Methods of bulk cryopreservation ofoocysts by vitrification using high aspect ratio cryopreservation devices are disclosed. Cryopreserved oocysts exhibit high viability, maintain infectivity in vitro, and are infectious to interferon-γ knockout mice. The course of the infection is comparable to that observed with unfrozen oocysts.
