Prevalence and copy numbers of C. suis affected by ages of pigs. Copy number (± SEM) is shown in the left ordinate (in red). Positive rate is shown in the right ordinate (in blue). FRET-qPCR were performed to determine the positivity and copy number of C. suis from nasal swabs of suckling pigs (n=324), weaned pigs (n=312), finisher pigs (n=100) and sows (n=195) in this study. The positivity of C. suis was the lowest in sow (P<0.01, 31.3%), followed by finisher pigs (84.0%) and weaned pigs (84.0%), and suckling pigs (P<0.05, 69.4%). The average copy number of C. suis was significantly higher in weaned pigs (P<0.01, 103.88±0.06 [SEM] per swab) than sows (103.11±0.09 per swab), finisher pigs (103.09±0.07 per swab) and suckling pigs (102.94±0.05 per swab).
