• Though now eliminated from developed countries, P.falciparum and therefore malaria tropica, the type of malaria caused by P. falciparum (Hausmann, 1996), run unchecked over most parts of Africa and elsewhere in the tropics and in turn this parasite is the greatest killer in these regions.

  • Plasmodium falciparum consists of a sexual and asexual form, which have hindered genetic analyses, but with conventional methods, such as micro-manipulation in which cells containing a single parasite can be identified, cloning and studying of the genome has been performed (Walliker, 1983) and information in regards to the genome of P. falciparum has been collected. (ubc.ca)

  • Genetic variability of Plasmodium falciparum underlies its transmission success and thwarts efforts to control disease caused by this parasite. (sciencemag.org)
  • Genetic variation in antigenic, drug resistance, and pathogenesis determinants is abundant, consistent with an ancient origin of P. falciparum , whereas DNA variation at silent (synonymous) sites in coding sequences appears virtually absent, consistent with a recent origin of the parasite. (sciencemag.org)
  • RBCs carrying PfEMP1 on their surface stick to endothelial cells, which facilitates further binding with uninfected RBCs (through the processes of sequestration and rosetting), ultimately helping the parasite to both spread to other RBCs as well as bringing about the fatal symptoms of P. falciparum malaria. (wikipedia.org)
  • He then called the organism that he saw after himself, Laverania falcipara, which later became known as Plasmodium falciparum (Garnham, 1966). (ubc.ca)

  • Transfection signals from native CAT-encoding DNA compared well with those from a synthetic DNA sequence adapted to the P. falciparum major codon bias, demonstrating effective expression of the bacterial sequence despite its use of rare P. falciparum codons. (pnas.org)
  • Once the mosquito becomes infected with Plasmodium falciparum it transfers the disease to each new host it penetrates. (kenyon.edu)
