Natural transformation stability analysis of H. parasuis SC1401 after continuously passaging. The natural frequencies of every 10 generations of H. parasuis SC1401 were determined through TSB++ transformation methodology (Inline graphic) and TSA++ transformation methodology (Inline graphic). The natural transformation frequency was determined from the number of antibiotic-resistant cfu mL−1 divided by the total cfu mL−1 scored on non-selective agar. Data points represent the mean values of three replicates, and error bars indicate standard deviations.
