The pfmdr1 & pfcrt Molecular Surveyor is an interactive mapping tool that provides researchers and policy makers with an overview of the changes in the prevalence of molecular markers associated with malaria drug resistance over time and location. It helps to inform international, regional and national surveillance strategies. 

The pfmdr1 & pfcrt Molecular Surveyor

  • Summarises baseline data from more than 373 published and unpublished studies on molecular markers of antimalarial drug resistance between 2001 and 2015
  • Focuses on resistance markers for amodiaquine (AQ), chloroquine (CQ), lumefantrine (LUM) and mefloquine (MQ) found in Plasmodium falciparum malaria parasite pfmdr1 and pfcrt genes
  • Enables you to filter data based on antimalarial treatment type, resistance marker, country, sample size and time
  • Lets you download data as csv file
  • Displays further detailed information about all the studies selected within the Surveyor in summary and reference tables
  • Permits you to view the study site and country by hovering the mouse cursor over a map pin. You can then click on the pin to view more detailed information about the study site, and click on the publication tab to view the associated publication within PubMed
