| Abstract: | Abstract The amoebo-flagellate transformation that occurs when Naegleria gruberi is transferred from growth medium to distilled water can be suppressed by the addition of ions. At concentrations of 3.2 mM and above the percentage of amoeba enflagellating decreases as the concentration of KCl, NaCl, LiCl, CaCl2 and MgCl2 is increased. KCl, alone, shows a marked trough, with a minimum at 1.2 mM, in enflagellation over the concentration range 0–3.2 mM. |
