Abstract : Investigations are reported on the adaptation of Entamoeba histolytica strains to low temperature conditions. Nine strains of E. histolytica which have been collected in Korea were subjected to low temperatures (30-32C). The lowest critical temperature of these strains was found to be 30C. Electron microscopy of Entamoeba histolytica in culture and in intestinal mucosa are described. The ultrastructural differences among E. histolytica trophozoites and precyst-like forms cultivated in vitro and trophozoites in intestinal mucosa of experimentally infected rabbit, using YS 27 strain were studied.
