Induced encystment improves resistance to preservation and storage of Acanthamoeba castellanii [PDF]

, 2008
Several conditions that allow the preservation, storage and rapid, efficient recovery of viable Acanthamoeba castellanii organisms were investigated. The viability of trophozoites (as determined by time to confluence) significantly declined over a period
