Enrolment and specimen collection should follow the criteria as defined by the governing human use protocol. Specimens: Collect a minimum of 100 specimens from human participants, process and preserve them for molecular testing. Lab testing: Determine the status of infection with Leishmania and Trypanosoma spp in 100 human specimens using serological or molecular methods. Data sharing: Provide information on collection sites up to the district level, clinical and other relevant epidemiological data and laboratory testing results as requested by NAMRU SOUTH Parasitology. DATA SHARING The contractor shall provide data collection information on field sites, entomological specimen numbers recorded, sand flies and triatomines species identified per collection period per site, specimen inventory, and relevant epidemiological data as requested by NAMRU SOUTH Entomology. The contractor shall provide information on enrollment site up to the district level and if possible, up to the household level, clinical symptoms and other relevant epidemiological data as requested by NAMRU SOUTH Parasitology. At the completion of a study or when requested, the contractor shall provide all data to NAMRU SOUTH. The contractor shall provide laboratory testing data as requested by NAMRU SOUTH Parasitology and Entomology. Provide input for report, scientific manuscripts and thesis preparation and participate on authorship of resulting products. EQUIPMENT, SUPPLIES AND MATERIALS The contractor will cover the cost of supplies and materials necessary for sample collection, transport, storage and screening. Depending on funding availability, NAMRU SOUTH may provide DNA extraction kits, PCR primers and master mix for up to 200 subjects per performance period. The contractor shall provide all required equipment. No Government Furnished equipment will be provided. SHIPMENTS The contractor shall cover the cost of one shipment of samples per year to NAMRU SOUTH Lima facilities per year upon coordination with the Department of Parasitology. The delivery address is: Parasitology – NAMRU SOUTH Av. Venezuela cd 36 S/N – Bellavista – Callao The Contractor shall include the following into the shipments of samples: Clinical samples collected as part of the study.
