Popis:	Using a closed-circuit television system, Entamoeba histolytica strain IP-106 was observed to penetrate through a meniscus separating a medium–nitrogen gas interface. Both the forces exerted on the amoeba by the surface tension of the liquid medium and the resultant forces applied by the amoeba, at various stages during penetration, were calculated. During penetration the force applied increased to a maximum of 3.3 × 10−6 N. However it was found that the shape of the amoeba allowed it to penetrate with a constant pressure. Intercellular movement due to active pseudopodial motion may play an important role in the process of penetration.
