Relationship of partial rpoB gene sequences inferred by the neighbor-joining method for Canadian study strains of C. pyruviciproducens. Relationship of partial rpoB gene sequences inferred by the neighbor-joining method for Canadian study strains of C. pyruviciproducens. The numbers at the nodes are bootstrap values (percentage based on 1,000 replications); only values ≥50% shown. GenBank accession numbers are given in parentheses. Bar, 0.1 substitution per nucleotide position, with Corynebacterium diphtheriae used as the outgroup. D. Goldenberger et al. J. Clin. Microbiol. 2014; doi:10.1128/JCM.00792-14
