Extract

1. The total bacterial floras from invasive strains of Entamoeba histolytica, when added to non-invasive strains, do not increase the invasiveness of the latter.

2. The bacterial flora of non-invasive strains do not inhibit the invasiveness of virulent strains.

3. Bacteria from a virulent substrain (revived by serial liver passage) do not increase the invasiveness of the attenuated parent strain.

4. It is concluded that the virulence of a strain of E. histolytica is primarily dependent upon the invasiveness of the amoeba itself.
