Percolation technique of walker to evaluate Plasmodium vivax Grassi and Plasmodium malariae Laveran in Ashaninkas communities from Satipo (Junín, Peru)

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 techniques were higher in Puerto Prado community; but statistically independent with age and sex. The advantage of precoloration technique of Walker was investigated and some factors that would influence variations in the prevalence of infection and density of parasites of plasmodia assayed dependent on what communities were sampled, age and sex.

Se evaluó la técnica de precoloración de Walker en comparación con la técnica de Giemsa clásica como método de diferenciación para las especies de Plasmodium vivax y Plasmodium malaria, en 208 muestras de sangre de siete comunidades Asháninkas en el distrito de Río Tambo, Satipo, Junín, Perú. La densidad parasitaria por el sistema de cruces (+) y por parásitos/mL fue mayor en la técnica de precoloración de Walker. La prevalencia del parásito en el total de muestras evaluadas fue: P vivax (24,52%) y P. malariae (0,48%). De las siete comunidades evaluadas en el distrito de Río Tambo: Puerto Ocopa, Unión Puerto Asháninka y Shimavenzo presentaron la mayor prevalencia de infección con 42,42%, 27,27% y 27,27% respectivamente. Las edades de 0 a 10 años y 41-50 años presentaron la mayor prevalencia de infección con 31,30% y 40% respectivamente. La prevalencia de infección por plasmodio fue independiente del sexo. La densidad de parásitos/mL por ambas técnicas de diferenciación, fue mayor en la comunidad Puerto Prado, pero estadísticamente independiente de los grupos etáreos y el sexo. Se analizan las ventajas de la técnica de la precoloración de Walker y algunos factores que influirían en las variaciones en la prevalencia de infección y densidad parasitaria de los plasmodios en dependencia de las comunidades evaluadas, grupos etáreos y el sexo.
