La técnica de precoloración de walker para evaluar plasmodium vivaxgrassi y plasmodium malariaes laveran en comunidades asháninkas en satipo (Junín, Perú)

Abstract

The precoloration tecllnique 01 Walker was assayed in comparison with the classic Giemsa technique as a differential method to Plasmodium vivax and Plasmodium malariae, in 208 blood samples 01 seven Ashaninka communities lrom Rio Tambo district, Satipo, Junin, Peru. Density 01 parasites by crossing system (+) and by parasites/mL were higher with precoloration 01 Walker. The prevalence 01 the parasites was to P vivax (24 ,52%) and P malariae (0,48%) 01 all samples assayed, 01 the seven communities evaluated from Rio Tambo district: Puerto Ocopa, Unión Puerto Ashaninka and Shimavenzo communities showed the highest prevalence 01 infection with 42,42%, 27,27% Y 27,27% respectively. The ages between O to 10 and 41-50 years showed the highest prevalence 01 infection with 31,30% and .40% respectively, The prevalence 01 inlection was independent with the sex, Density 01 parasites/mL with both techniques were higher in Puerto Prado community; but statistically independent with age and sex, The advantage of precoloration technique 01 Walker was investigated and some lactors that would influence variations in the prevalence 01 inlection and density of parasites 01 plasmodia assayed dependent on what communities were sampled, age and sexo.
