Bacterial Endosymbionts as Extrachromosomal Elements in Amebas

  • Kwang W. Jeon
Part of the Basic Life Sciences book series (BLSC, volume 40)


While some free-living amebas (3,4,6,7,8,22,31) and other types of cells (5,11,14,29,30) have been known to carry infective or symbiotic bacteria, the roles of such bacteria have not been studied in detail. In one case, bacterial infection of soil amebas was found to be harmful, leading to the lysis of infected amebas within several days (9). In another, symbiotic bacteria were thought to function as substitutes for mitochondria that were absent from the cytoplasm of the giant ameba, Pelomyxa palustris (7).
