One possible strategy to find novel anti-malarial drugs is to access the largest reservoir of genomic biodiversity source on earth present in metagenomes of environmental microbial communities. METHODS: A bioluminescent P. falciparum parasite was used to quickly detect shifts in viability of microcultures grown in 96-well plates. A synthetic gene encoding the Dermaseptin 4 peptide was designed and cloned under tight transcriptional control in a large metagenomic insert context (30 kb) to serve as proof-of-principle for the screening platform. RESULTS: Decrease in parasite viability consistently correlated with bioluminescence emitted from parasite microcultures, after their exposure to bacterial extracts containing a plasmid or fosmid engineered to encode the Dermaseptin 4 anti-malarial peptide. CONCLUSIONS: Here, a new technical platform to access the anti-malarial potential in microbial environmental metagenomes has been developed.6 p.application/pdfengcc by (c) Mongui et al., 2015http://creativecommons.org/licenses/by/3.0/es/GenòmicaGenètica microbianaMalàriaPlasmodium falciparumResistència als medicamentsEfecte dels medicaments sobre els microorganismesGenomicsMicrobial geneticsMalariaPlasmodium falciparumDrug resistanceEffect of drugs on microorganismsDevelopment of a genetic tool for functional screening of anti-malarial bioactive extracts in metagenomic librariesinfo:eu-repo/semantics/article2016-02-02info:eu-repo/semantics/openAccess26040274
