Use of Single Nucleotide Polymorphisms in the plcR Gene for Specific Identification of Bacillus anthracis

Easterday, W. Ryan, Van Ert, Matthew N., Simonson, Tatum S., Wagner, David M., Kenefic, Leo J., Allender, Christopher J., ...

A TaqMan-minor groove binding assay designed around a nonsense mutation in the plcR gene was used to genotype Bacillus anthracis, B. cereus, and B. thuringiensis isolates. The assay differentiated B....

Strain-Specific Single-Nucleotide Polymorphism Assays for the Bacillus anthracis Ames Strain† ▿

Van Ert, Matthew N., Easterday, W. Ryan, Simonson, Tatum S., U'Ren, Jana M., Pearson, Talima, Kenefic, Leo J., ...

Highly precise diagnostics and forensic assays can be developed through a combination of evolutionary analysis and the exhaustive examination of genomic sequences. In Bacillus anthracis, whole-genome...
