Comparison of PCR-RFLP, ribotyping and ERIC-PCR for typing Bacillus anthracis and Bacillus cereus strains.

PCR-RFLP analysis of the vrrA gene and cerAB gene was used to investigate the genomic diversity in 21 strains of Bacillus anthracis and 28 strains of Bacillus cereus, and was compared with results obtained by ribotyping and enterobacterial repetitive intergenic consensus-PCR (ERIC-PCR) analysis. VrrA-typing divided the B. anthracis into four groups. Except for one Pasteur vaccine strain, the vrrA PCR-RFLP profiles of the B. anthracis were separated into three groups, which were different from those of the B. cereus strains. Ribotyping separated the B. anthracis isolates into seven ribotypes, and a common fragment of an approximately 850 bp band from the ERIC-PCR fingerprints separated most B. anthracis strains into two groups. VrrA/cerAB PCR-RFLP, ribotyping and ERIC-PCR generated 18, 22 and 23 types, respectively, from B. cereus strains. The results suggest that a combination of all three methods provides a high resolution typing method for B. anthracis and B. cereus. Compared with ribotyping and ERIC-PCR, PCR-RFLP is simple to perform and has potential as a rapid method for typing and discriminating B. anthracis strains from other B. cereus group bacteria.[1]
