Fig. 1From: Nitric oxide maintains cell survival of Trichomonas vaginalis upon iron depletion T. vaginalis extends the survival time when cultured under iron-deficient conditions. The growth of cells cultured in iron-rich (IR, 80 μM FAC, a) and -deficient (ID, 180 μM DIP, b) media. The number of viable cells was monitored every three hours using the trypan blue exclusion assay. The initial cell density is 1 × 106cells/ ml. The data are presented as the mean ± SD of three independent experimentsBack to article page
