 Notes: Only infected mosquitoes were considered for the calculation of the median number of oocysts and its IQR. Pvalues from the comparison of the proportion of infected mosquitoes of a colony against the reference strain are indicated as superscripts (underlined are those having significance)
 ^{a}Compared to the reference mosquitoes, the number of oocysts was significantly lower in the Guatemala colony (P = 0.002) when fed with parasite genotype Vk247/Pvs25B. Statistical significance was calculated by using the Jackknife coefficient variance estimator at 95% confidence interval (according to models described in method section)
 Abbreviations: n total number of mosquitoes examined, Prop. proportion, A/WSR reference strain of An. albimanus, P/TAPR reference strain of An. pseudopunctipennis, LF Lacandon Forest, IQR interquartile range
