PROTOZOA

The pathogenic protozoa include Entamoeba histolytica (causing amoebic dysentery), and members of the Hartmanella-Naegleria group (causing meningo-encephalitis) (see Table 7.5). The cyst stage in the life cycle of protozoa is the primary means of dissemination as the amoeba die quickly once outside the human body. Cysts must be kept moist in order to remain viable for any extended period.¹⁷
