Table 1 Plasmodium vivax infected blood: parasitaemia, gametocytaemia and exflagellation rates for each parasite genotype

From: Plasmodium vivax CSP-Pvs25 variants from southern Mexico produce distinct patterns of infectivity for Anopheles albimanus versus An. pseudopunctipennis, in each case independent of geographical origin

Blood infection with P. vivax genotypes: cspVk/Pvs25-130 n Median (IQR) of parasites/μl of blood Median (IQR) of gametocytes/μl of blood n Median (IQR) of exflagellations/μl of blood
Vk210/Pvs25-Aa 9 5040 (4400–6960) 225 (113–288) 10 36 (12–116)
Vk210/Pvs25-B 16 4360 (2800–6000) 218 (116–628) 16 18 (4–50)
Vk247/Pvs25-Bb 54 8000 (4640–14,640) 617 (259–1120) 50 42 (20–152)
  1. Notes: Parasitaemia was higher with genotype Vk247/Pvs25-B versus Vk210/Pvs25-B (P = 0.003). Gametocytaemia was higher with genotype Vk247/Pvs25-B versus Vk210/Pvs25-A (P = 0.022) or Vk210/Pvs25-B (P = 0.037). There were no differences in the number of exflagellations between genotypes (P = 0.086). Kruskal-Wallis test by ranks (95% CI)
  2. aParasitaemia and gametocytaemia were missing from one sample
  3. bThe exflagellation values were missing from four samples
  4. Abbreviation: n, number of parasite isolates
