[Cytochemical study on the activity of enzymes in trophozoites of Entamoeba histolytica from the cecum of guinea pigs with invasive and non-invasive amebiasis].

Experimental amoebiasis was inflicted on guinea pigs using the PS-2 strain of Entamoeba histolytica. Cytoenzymatic studies were conducted on the trophozoites sampled from the caecum of hosts with non-invasive and invasive amebiasis. The results show higher intensity of the processes of intracellular digestion, transportation, and anaerobic respiration in the amoebae originating from intestine of the host with infective amoebiasis.
