| Abstract: | The primary structures of the 23S ribosomal RNA genes of Bacillus anthracis and an emetic strain of Bacillus cereus were determined by direct sequencing of enzymatically amplified chromosomal DNA. The 23S rRNA gene sequences of B. anthracis and B. cereus were found to be almost identical and showed only two differences (a single nucleotide change, and a single base insertion in B. cereus). The feasibility of using PCR-direct sequencing for the rapid sequence determination of large-subunit rRNA genes is demonstrated. |
