Modeling malaria genomics Microbiology

To study the effects of malaria-control interventions on parasite population genomics, we examined a set of 1,007 samples of the malaria parasite Plasmodium falciparum collected in Thiès, Senegal between 2006 and 2013. The parasite samples were genotyped using a molecular barcode of 24 SNPs. About 35% of the samples grouped...

(University of Bern) An international scientific consortium led by the cell biologists Volker Heussler from the University of Bern and Oliver Billker from the Ume å University in Sweden has for the first time systematically investigated the genome of the malaria parasite Plasmodium throughout its life cycle in a large-scale experiment. The researchers were able to identify hundreds of targets that are urgently needed in drug and vaccine development to eradicate the disease.

The objective of this study was to evaluate the in vitro antiplasmodial properties against malaria parasite in 15 plants mentioned in Indian traditional medicine texts.MethodsIn vitro antiplasmodial activity of methanolic extracts obtained from Indian traditional medicinal plants was evaluated on Plasmodium falciparum of FCK2 and INDO strains using schizont maturation inhibition assay and parasite lactate dehydrogenase inhibition assay.ResultsMethanolic extracts of Adhatoda zeylanica, Embelia ribes, Piper nigrum and Plumbago zeylanica exhibited more than 50% inhibition in both the stains in schizont maturation inhibition a...

Malaria, one of the largest health burdens worldwide, is caused by Plasmodium spp. infection. Upon infection, the host ’s immune system begins to clear the parasites. However, Plasmodium species have evolved to es...

This study describes the genetic diversity and population structure from September 2012 to March 2015 in three geographically distant settlements, Cahuide (CAH), Lupuna (LUP) and Santa Emilia (STE), located in the Peruvian Amazon. A total 777P.vivax mono-infections, out of 3264, were genotyped. Among study areas, LUP showed 19.7% of polyclonal infections, and its genetic diversity (Hexp) was 0.544. Temporal analysis showed a significant increment of polyclonal infections andHexp, and the introduction and persistence of a new parasite population since March 2013. In STE, 40.1% of infections were polyclonal, withHexp = 0.596...

Abstract Malaria is a disease of public health importance in many parts of the world. Currently, there is no effective way to eradicate malaria, so developing safe, efficient, and cost-effective vaccines against this disease remains an important goal. Current research on malaria vaccines is focused on developing vaccines against pre-erythrocytic stage parasites and blood-stage parasites or on developing a transmission-blocking vaccine. Here, we briefly describe the progress made towards a vaccine against Plasmodium falciparum, the most pathogenic of the malaria parasite species to infect humans. PMID: 3168740...

Abstract Plasmodium vivax, the chronic relapsing human malaria parasite with the most widespread distribution, possesses proteins associated with the merozoite surface that could be targets for host immune responses and potential vaccine candidates. Of these, the merozoite surface protein 3 of P. vivax (PvMSP3) is an attractive vaccine target as well as a genetic marker for epidemiological surveillance. PvMSP3 comprises a group of protein members encoded by a multigene family. Although some protein members, i.e. PvMSP3α and PvMSP3β, have been targets for molecular and immunological investigations, the m...
