The P. falciparum 3D7 nuclear genome is composed of 22.8 megabases (Mb) distributed among 14 chromosomes ranging in size from approximately 0.643 to 3.29 Mb (Fig. 1, and Supplementary Figs AâN). Thus the P. falciparum genome is almost twice the size of the genome of the fission yeast Schizosaccharomyces pombe.
The time period from initial parasite infection to the appearance of symptoms varies according to the particular species of Plasmodium that infects an individual. For example, P. malariae ranges from about 18-40 days, while P. falciparum ranges from nine to 14 days, and 12-18 days for P. vivax and P. ovale. Initial symptoms of malaria may include shaking chills, high fevers, sweating, headaches, nausea and vomiting, anemia, and/or diarrhea.
