Table 1 Protection against challenge

From: Daily Plasmodium yoelii infective mosquito bites do not generate protection or suppress previous immunity against the liver stage

Mice experimental conditions Threshold cycle (Ct) in real time-PCR Number of mice (protected/total)
Irradiated mosquito bites > 40 (3/3)
Normal mosquito bites 17 ± 0.85 (0/3)
Immunized > 40 (3/3)
Immunized + normal mosquito bites > 40 (3/3)
  1. Groups of mice were challenged with 104 P. yoelii-GFP sporozoites injected intravenously. Real-time PCR was run for 40 cycles, therefore Ct > 40 indicates no detection of parasite in the liver.
