SIMILARITY IN BASE COMPOSITIONS OF DEOXYRIBONUCLEATES FROM SEVERAL STRAINS OF BACILLUS CEREUS AND BACILLUS ANTHRACIS

Abstract
McDonald, William C. (U.S. Army Biological Laboratories, Frederick, Md.), Ira C. Felkner, Abraham Turetsky, and Thomas S. Matney . Similarity in base compositions of deoxyribonucleates from several strains of Bacillus cereus and Bacillus anthracis . J. Bacteriol. 85: 1071–1073. 1963.—Studies were made on the base compositions of the deoxyribonucleates of a number of Bacillus species. Species homogeneity was quite evident from these studies since, with only one exception, several strains of the same species showed identical base compositions. It was found that the melting temperatures and corresponding percentages of guanine plus cytosine were quite similar in several strains of B. cereus and B. anthracis . These aspects are discussed as related to their possible genetic homology.
