MCA of the 352-bp amplicon of the gyrA genes of Arcobacter butzleri, Arcobacter cryaerophilus, Arcobacter cibarius, and Arcobacter nitrofigilis obtained with the real-time PCR assay. The melting peaks generated from the dissociation of the fluoroprobes from the Arcobacter species with four different Tms can be observed. Values on the y axis represent the ratio of the first negative derivative of the change in fluorescence [d(F2/F1)] to the variation in temperature (dT).
