Growth rates of Paramoeba perurans cultures under different temperature and salinity conditions were investigated in vitro over a 15day period. Optimal population growth, under the experimental conditions, was observed at 15°C and a salinity of 35, with amoebae populations doubling every 14h. Positive P. perurans populations growth was observed at 15°C between salinities of above 20 and 50, and at 8°C, 11°C and 18°C at salinities between 25 and 50, 50 being the maximum salinity tested. Amoebae numbers were sustained at 4°C. Therefore, lower temperature and salinity thresholds for P. perurans population growth lie between 4 to 8°C, and salinities of 20 to 25, respectively. Upper limits were not determined in this study. The populations remained relatively stable at 4°C and 2°C at permissive salinities with respect to numbers of viable amoebae over the 15day exposure period.
