FIG 2.
Comparison of all CT values of concordant (culture positive/PCR positive; group 3) and discordant (culture negative/PCR positive; group 2) specimens for C. jejuni/C. coli, Salmonella spp., and Shigella spp (A), C. jejuni/C. coli only (B), Salmonella spp. only (C), and Shigella spp. only (D). The median CT values of the concordant specimens were lower than those of the discordant specimens; this difference was statistically significant (C. jejuni/C. coli, P < 0.001; Salmonella spp., P = 0.02; and Shigella spp., P = 0.02).
