Comparison of parasite load, by host and Plasmodium species, based on quantitative PCR targeting 18S rRNA gene in humans and NHPs from the Yavarí-Mirín River basin, Loreto region, Peru*

Host Parasite species log10 DNA/μL, mean +SD Comparison p value
NHP, n = 57 P. brasilianum/P. malariae 1.2 +0.8 vs. P. vivax/P. simium (NHP) 0.023
NHP, n =7 P. vivax/P. simium 0.6 +0.3 vs. P. vivax/P. simium (human) 0.044
Human, n = 43 P. vivax/P. simium 1.2 +1.0 vs. P. brasilianum/P. malariae (NHP) 0.851

*Parasite load expressed as log10-transformed DNA concentration per μL. Statistical comparisons performed using pairwise tests between groups. NHP, nonhuman primate.
