Table 6 Parasite densities of isolates with monoinfections of P. falciparum and of P. vivax collected in dry and in wet seasons

From: Simultaneous detection of Plasmodium vivax and Plasmodium falciparum gametocytes in clinical isolates by multiplex-nested RT-PCR

Category Parasite density (parasites/μL)
  Dry season Wet season
P. falciparum*   
with gametocyte n = 3 n = 5
range 1560–7000 930–36630
median 2960 6695
no gametocyte n = 40 n = 27
range 0–288360 0–110840
median 22280 17800
P. vivax*   
with gametocyte n = 17 n = 11
range 11640–70080 # 6090–49320 #
median 19360 9630
no gametocyte n = 29 n = 21
range 0–36360 304–16360
median 6560 2740
  1. * Verification of monoinfection by 18S rRNA PCR.
  2. # Parasite densities between isolates with and without detectable gametocytes by microscopy were significantly different (p < 0.001, Mann–Whitney U test).
