The precoloration technique of Walker was assayed in comparation with the classic Giemsa technique as a differential method to Plasmodium vivax and Plasmodium malariae, in 208 blood samples of seven Ashaninka communities from Rio Tambo district, Satipo, Junin, Peru. Density of parasites by crossing system (+) and by parasites/mL were higher with precoloration of Walker. The prevalence of the parasites was to P. vivax (24,52%) and P. malariae (0,48%) of all samples assayed. Of the seven communities evaluated from Rio Tambo district: Puerto Ocopa, Unión Puerto Ashaninka and Shimavenzo communities showed the highest prevalence of infection with 42,42%, 27,27% y 27,27% respectively. The ages between 0 to 10 and 41-50 years showed the highest prevalence of infection with 31,30% and 40% respectively. The prevalence of infection was independent with the sex. Density of parasites/mL with both t...
