Assessment of the sensitivity of nested PCR for T. vaginalis in comparison with the microscopy test. a Sensitivity analysis of PCR assay on agarose gel. b Sensitivity analysis of microscopy. M, 100-bp DNA molecular size markers; +, positive control (T. vaginalis); −, negative control (human DNA). 1–4, Serial diluted BALF containing T. vaginalis (0.1, 1, 10, 102 trichomonads/μl); the red square indicates positive results for microscopy; the green square indicates negative results for microscopy
