    • Genetic Surveillance Detects Both Clonal and Epidemic Transmission of Malaria following Enhanced Intervention in Senegal 

      Daniels, Rachel Fath; Chang, Hsiao-Han; Séne, Papa Diogoye; Park, Danny C.; Neafsey, Daniel Edward; Schaffner, Stephen; Hamilton, Elizabeth Julia; Lukens, Amanda Kathleen; Van Tyne, Daria Natalie; Mboup, Souleymane; Sabeti, Pardis Christine; Ndiaye, Daouda; Wirth, Dyann Fergus; Hartl, Daniel L.; Cooke, Sarah Volkman (Public Library of Science, 2013)
      Using parasite genotyping tools, we screened patients with mild uncomplicated malaria seeking treatment at a clinic in Thiès, Senegal, from 2006 to 2011. We identified a growing frequency of infections caused by genetically ...

    • A Global Transcriptional Analysis of Plasmodium Falciparum Malaria Reveals A Novel Family of Telomere-Associated lncRNAs 

      Broadbent, Kate Mariel; Park, Daniel John; Wolf, Ashley Robin; Van Tyne, Daria Natalie; Sims, Jennifer Sung; Ribacke, Ulf Erik; Cooke, Sarah Volkman; Duraisingh, Manoj T.; Wirth, Dyann Fergus; Sabeti, Pardis Christine; Rinn, John L (BioMed Central, 2011)
      Background: Mounting evidence suggests a major role for epigenetic feedback in Plasmodium falciparum transcriptional regulation. Long non-coding RNAs (lncRNAs) have recently emerged as a new paradigm in epigenetic ...

    • Human Cerebral Malaria and Plasmodium falciparum Genotypes in Malawi 

      Milner, Danny Arnold; Vareta, Jimmy; Valim, Clarissa; Montgomery, Jacqui; Daniels, Rachel Fath; Cooke, Sarah Volkman; Neafsey, Daniel Edward; Park, Daniel John; Schaffner, Stephen; Mahesh, Nira C; Barnes, Kayla G; Rosen, David M; Lukens, Amanda Kathleen; Van-Tyne, Daria; Wiegand, Roger C.; Sabeti, Pardis Christine; Seydel, Karl B; Glover, Simon J; Kamiza, Steve; Molyneux, Malcolm E; Taylor, Terrie E; Wirth, Dyann Fergus (BioMed Central, 2012)
      Background: Cerebral malaria, a severe form of Plasmodium falciparum infection, is an important cause of mortality in sub-Saharan African children. A Taqman 24 Single Nucleotide Polymorphisms (SNP) molecular barcode assay ...

    • Identification and Functional Validation of the Novel Antimalarial Resistance Locus PF10_0355 in Plasmodium falciparum 

      Van Tyne, Daria Natalie; Park, Daniel John; Schaffner, Stephen; Neafsey, Daniel Edward; Angelino, Elaine Lee; Cortese, Joseph F.; Barnes, Kayla G.; Rosen, David M.; Lukens, Amanda Kathleen; Daniels, Rachel Fath; Milner, Danny Arnold; Johnson, Charles A.; Shlyakhter, Ilya; Grossman, Sharon Rachel; Becker, Justin S.; Yamins, Daniel Louis Kanef; Karlsson, Elinor Kathryn; Ndiaye, Daouda; Sarr, Ousmane; Mboup, Souleymane; Happi, Christian Tientcha; Furlotte, Nicholas A.; Eskin, Eleazar; Kang, Hyun Min; Hartl, Daniel L.; Birren, Bruce W.; Wiegand, Roger C.; Lander, Eric Steven; Wirth, Dyann Fergus; Cooke, Sarah Volkman; Sabeti, Pardis Christine (Public Library of Science, 2011)
      The Plasmodium falciparum parasite's ability to adapt to environmental pressures, such as the human immune system and antimalarial drugs, makes malaria an enduring burden to public health. Understanding the genetic basis ...

    • Malaria Life Cycle Intensifies Both Natural Selection and Random Genetic Drift 

      Chang, Hsiao-Han; Moss, Eli L.; Park, Daniel John; Ndiaye, Daouda; Mboup, Souleymane; Cooke, Sarah K.; Sabeti, Pardis Christine; Wirth, Dyann F.; Neafsey, Daniel Edward; Hartl, Daniel L. (Proceedings of the National Academy of Sciences, 2013)
      Analysis of genome sequences of 159 isolates of Plasmodium falciparum from Senegal yields an extraordinarily high proportion (26.85%) of protein-coding genes with the ratio of nonsynonymous to synonymous polymorphism greater ...

    • Modeling malaria genomics reveals transmission decline and rebound in Senegal 

      Daniels, Rachel Fath; Schaffner, Stephen; Wenger, Edward A.; Proctor, Joshua L.; Chang, Hsiao-Han; Wong, Wesley Philip; Baro, Nicholas; Ndiaye, Daouda; Fall, Fatou Ba; Ndiop, Medoune; Ba, Mady; Milner, Danny Arnold; Taylor, Terrie E.; Neafsey, Daniel Edward; Cooke, Sarah K.; Eckhoff, Philip A.; Hartl, Daniel L.; Wirth, Dyann F. (Proceedings of the National Academy of Sciences, 2015)
      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 ...

    • Rapid, Field-Deployable Method for Genotyping and Discovery of Single-Nucleotide Polymorphisms Associated with Drug Resistance in Plasmodium falciparum 

      Daniels, Rachel Fath; Ndiaye, Daouda; Wall, Mikeal; McKinney, Jason; Séne, Papa Diogoye; Sabeti, Pardis Christine; Volkman, Sarah K.; Mboup, Souleymane; Wirth, Dyann Fergus (American Society for Microbiology, 2012)
      Despite efforts to reduce malaria morbidity and mortality, drug-resistant parasites continue to evade control strategies. Recently, emphasis has shifted away from control and toward regional elimination and global eradication ...

    • Sequence-Based Association and Selection Scans Identify Drug Resistance Loci in the Plasmodium Falciparum Malaria Parasite 

      Park, Daniel John; Lukens, Amanda Kathleen; Neafsey, Daniel Edward; Schaffner, Stephen; Chang, Hsiao-Han; Valim, Clarissa; Ribacke, Ulf Erik; Van Tyne, Daria Natalie; Galinsky, Kevin Joseph; Galligan, Meghan; Becker, Justin S.; Ndiaye, Daouda; Mboup, Souleymane; Wiegand, Roger C.; Hartl, Daniel L.; Sabeti, Pardis Christine; Wirth, Dyann F.; Cooke, Sarah K. (Proceedings of the National Academy of Sciences, 2012)
      Through rapid genetic adaptation and natural selection, the Plasmodium falciparum parasite—the deadliest of those that cause malaria—is able to develop resistance to antimalarial drugs, thwarting present efforts to control ...
