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.
Morphology: The Adult Worm-Averaging 30mm in length and 13 mm in width, Fasciola hepatica is one of the largest flukes in the world. The adult worm has a very characteristic leaf shape with the anterior end being broader than the posterior end and an anterior cone-shaped projection.istory: Eggs of Fasciola hepatica have been found in mummies, showing that human infection was occurring at least as early as Pharaonic times (Farag). Indeed, F. hepatica was the first fluke or trematode to be reported. It was first discovered, however, not in humans, but in sheep where it causes a more obvious burden.
