RESUMEN
Se evaluó la presencia de infecciones maláricas en individuos asintomáticos en la población Jivi de Puente Parhueña. El estudio fue de tipo prospectivo en tres momentos. El diagnóstico parasitológico se realizó mediante el examen convencional de gota gruesa y extendido (GGE) y la reacción en cadena de la polimerasa (PCR). El diagnóstico por microscopia indicó 2% (5/261) de láminas positivas en Abril, 1% (3/274) en Septiembre y 4% (5/135) en Diciembre. La PCR para Plasmodium spp., fue 46% (26/57) en abril, 49% (28/57) en Septiembre y 35% (20/57) en Diciembre. En los tres momentos predominó la presencia de P. vivax. La prueba de ELISA demostró 72% (41/57) seroreactivos en Abril, 53% (30/57) en Septiembre y 60% (34/57) en Diciembre. En Puente Parhueña habitan individuos con infecciones maláricas asintomáticos, con persistencia de anticuerpos antimalaricos, que probablemente representan un reservorio de gametocitos dentro de la comunidad.
ABSTRACT
The study was carried out to determine the present malaria infection in the asymptomatic Jivi people of Puente Parhueña. The study was prospective over three periods of time. The parasitological diagnoses were from thick and thin blood smears (GGE) and polymerase chain reaction (PCR). The antibody search was performed by ELISA. Microscopy of the slides detected the following positive

results:

2% (2/261) April, 1% (3/274) September and 4% (5/135) December. Detection of Plasmodium by PCR was 46% (26/57) in April, 49% (28/57) in September y 35% (20/57) in December. Plasmodium vivax infected individuals predominated during these 3 times. Positives for ELISA were 72% (41/57) in April, 53% (30/57) September and 60% (34/57) December. The study demonstrated that people living in Puente Parhueña presented asymptomatic malaria infection with malaria antibodies persistence which likely represents a gametocyte potential reservoir for infection among the population.
