Figure 3. Comparison of U. urealyticum and U. parvum DNA load by quantitative real-time PCR and culture.

◊ =  female cervical swabs. ♦ =  female urethral swab. * =  male urethral swab. A total of 111 samples negative by both culture and qPCR, and one sample, which was culture positive in CCU group 4 but not re-detected with PCR, are not shown, as the species could not be determined. Co-infected specimens (5 samples) are not shown. Medians are depicted by a horizontal bar.
