SYNOPSIS Naegleria gruberi strains cloned from amebas isolated from a Vero cell culture (“TS”), a sewer drainage ditch (“PD”), and an established laboratory line (“S”) were morphologically identical except for differences in size and flagellate transforming ability. Cultivation on a Trypticase‐yeast extract‐glucose medium (“TYG”) fortified with autoclaved E. coli resulted in increased cell size of 2 strains. Differences also were noted in growth rates and optimal growth temperatures. The autoclaved E. coli in TYG medium was replaceable with serum only for strains TS and PD. A basal salts medium + autoclaved E. coli supported growth of all 3 strains, but the basal salts medium + serum would not support growth of any of the strains.
