Bacillus sphaericus 2362 liquid formulation, activity against Anopheles pseudopunctipennis and Culex quinquefasciatus larvae was tested in laboratory bioassays. Breeding place water and distilled water were used with concentrations of 1 x 10 11, 1,5 x 10 11, 2,5 x 10 11, 3,9 x 10 11 spores/mL. Target population was kept in laboratory conditions by using breeding native water and flora. One mL doses were added into test cups containing 25 II and III stage larvae and 150 mL of breeding water or distilled respectively; cups tests with the same amount of water and larvae were used as controls for each concentration, water type and larval specie tested. Testing was made three times for each concentration in laboratory conditions. Twelve replicas were made and divided in six for each species, using a total of 4800 larvae for species. Reading of larvae mortality were at 12, 24, 48, and 72 hours...

Introducción: La OMS y el sistema de información rutinaria en Salud (PRIMS) proponen la existencia de tres determinantes en los sistemas de información en salud (SIRS): los de comportamiento, técnicos, y organizacionales /ambientales, que requieren tener calidad para buen desempeño. Objetivos: Evaluar el sistema de información en Salud (SIRS) del Programa de ITS/VIH/sida en un hospital nivel III-1 de una zona de alta prevalencia. Diseño: Estudio descriptivo. Institución: Instituto de Medicina Tropical Daniel A. Carrión, Facultad de Medicina, UNMSM. Participantes: Personal de Salud involucrado y una muestra representativa de las dos últimas semanas registros del parte diario e historia clínica de las actividades de la ESNPC ITS-VIH/sida. Intervenciones: Se usó herramientas estandarizadas para evaluar estos determinantes. Resultados: Determinantes organizacionales: 60% percibe ...
