title: Isolation and partial characterization of two plasmid deoxyribonucleic acids from endosymbiotic bacteria of Amoeba proteus.
abstract: Obligatory endosymbiotic bacteria in a strain of Amoeba proteus were found to harbor two distinct species of plasmid, pHJ11 and pHJ12. Their molecular weights were 39 x 10(6) and 14 x 10(6), respectively.
