Abstract
Circular deoxyribonucleic acid was isolated from Shigella dysenteriae Y6R and was found to consist of six species having molecular weights of 10^6, 1.3 x 10^6, 2.6 x 10^6, 3.8 x 10^6, 20 x 10^6, and 24 x 10^6 daltons. These size classes were partially resolved by sucrose density gradient centrifugation. The minicircles (10^6 and 1.3 x 10^6) were found to have a buoyant density in CsCl of 1.710 g/ml. The 3.8 x 10^6 dalton class had a density of 1.707 g/ml. The two largest species had a density of 1.702 g/ml. Two other strains, S. sonnei II and S. dysenteriae 60, also contained circular deoxyribonucleic acid.
