ABSTRACT
We are investigating the structure and biosynthesis of glycosyl-phosphatidylinositols (GPI) in the protozoa Toxoplasma gondii, Plasmodium falciparum, Plasmodium yoelii and Paramecium primaurelia. This comparison of structural and biosynthesis data should lead us to common and individual features of the GPI-biosynthesis and transport in different organisms.

The effect of adding two different organic materials; wheat extract and bactopeptone, was studied on some of the most abundant bacterivorous hymnostomes collected from freshwater canal in Shebin El-Koum, Monoufia. It was found that some of these ciliates prefer plant protein as wheat, others prefer animal protein as bactopeptone, someone have the ability to accommodate with both organic materials. A significant positive relationship between log doubling times and log cell volumes of these hymnostomes was confirmed
