Parasitemia distribution in the symptomatic and asymptomatic groups. Semilogarithmic plots of asexual forms (a) and gametocytes (b) as determined by microscopy and parasite density estimated by the number of copies of 18S rRNA (c) and pvs25 (d) are shown for symptomatic and asymptomatic blood samples. The symptomatic group showed the significantly higher density of both asexual forms (a) and gametocytes (b) (P < 0.0001) the parasite density was observed in the number of copies of 18S rRNA (c) and pvs25 transcripts (d). The means were compared using the Mann-Whitney test (****P < 0.0001), and the error bars represent the standard error of the mean (SEM)
