We evaluated digital PCR (dPCR) to directly enumerate plasmid and chromosome copies in three strains of Bacillus anthracis. Copy number estimates based on conventional quantitative PCR (qPCR) highlighted the variability of using qPCR to measure copy number whereas estimates based on direct sequencing are comparable to dPCR.

Bacillus anthracis is one of the most genetically homogeneous pathogens described, making strain discrimination particularly difficult. In this paper, we present a novel molecular typing system based on rapidly evolving variable-number tandem repeat (VNTR) loci. Multiple-locus VNTR analysis (MLVA) uses the combined power of multiple alleles at several marker loci. In our system, fluorescently l...
