Correlation between oocyst and sporozoite load. a A stacked column comparing the average oocyst load (horizontal axis) to the sporozoite load (vertical axis) is shown. Sporozoite gland index are denoted by 1+ (blue), 2+ (orange), 3+ (grey), and 4+ (yellow). The number of positive mosquitoes are shown inside the coloured bars. b, c Linear regression to study correlation between average oocyst load and percentage of mosquitoes (out of total dissected) that had gland index of 3+ and 4+, respectively. Oocyst numbers were obtained on days 7/8 post feeding
