Temperature Sensitivity: A Cell Character Determined by Obligate Endosymbionts in Amoebas

K. W. JEON 1 and T. I. AHN 1

1 Department of Zoology, University of Tennessee, Knoxville 37916

A strain of Amoeba proteus has lost its ability to survive at temperatures above 26°C as a result of becoming dependent on endosymbiotic bacteria that are psychrophile-like. The observed temperature sensitivity develops in fewer than 200 host cell generations (18 months of culture) after the host cells are experimentally infected with the symbionts.
