  • a Values shown for results of genotyping are given in percentages. Two-way comparisons were performed for each gene, strain, or replicon studied between the different groups examined, using Fisher's exact test. For each comparison, a P value of <0.05 (+) was considered statistically significant, and a P value of <0.01 (++) was also considered statistically significant, while a P value of >0.05 (−) was not considered statistically significant. epi, episomal; chrom, chromosomal; Phylo, phylotype.
