These flowers emerge from very large, cabbage-like, maroon or dark brown buds typically about 30 cm (12 in) wide, but the largest (and the largest flower bud ever recorded) found at Mount Sago, Sumatra in May 1956 was 43 cm (17 in) in diameter. [19] Indonesian researchers often refer to the bud as a 'knop' (knob). [14]
The ring stages grow slowly but soon fill one-fourth to one-third of the parasitized cell. [2] Pigment increases rapidly and the half-grown parasite may have from 30 to 50 jet-black granules. [2] The parasite changes various shapes as it grows and stretches across the host cell to form the band form. [2]
Plasmodium parasites maintain a single copy of their genome through much of the life cycle, doubling the genome only for a brief sexual exchange within the midgut of the insect host. [3] Attached to the nucleus is the endoplasmic reticulum (ER), which functions similarly to the ER in other eukaryotes.
Placentonema gigantissima is a giant nematode that parasitizes the placenta of the sperm whale.With a length of 8.4 metres (28 ft) and a diameter of 2.5 centimetres (0.98 in), it is potentially the largest nematode worm ever described, inhabiting the largest mammals of the world. [1]
Fasciolopsis buski is commonly called the giant intestinal fluke, because it is an exceptionally large parasitic fluke, and the largest known to parasitise humans. Its size is variable and a mature specimen might be as little as 2 cm long, but the body may grow to a length of 7.5 cm and a width of 2.5 cm.
Rafflesia (/ r ə ˈ f l iː z (i) ə,-ˈ f l iː ʒ (i) ə, r æ-/), [2] or stinking corpse lily, [3] is a genus of parasitic flowering plants in the family Rafflesiaceae. [4] The species have enormous flowers, the buds rising from the ground or directly from the lower stems of their host plants; one species has the largest flower in the world.
Leucocytozoon (or Leukocytozoon) is a genus of parasitic alveolates belonging to the phylum Apicomplexa (which also includes the malaria parasites). The species of this genus use either blackflies (Simulium species) or a biting midge as their definitive host and birds as their intermediate host. [1] There are over 100 species in this genus.
Trypanosoma is a genus of kinetoplastids (class Trypanosomatidae [1]), a monophyletic [2] group of unicellular parasitic flagellate protozoa. Trypanosoma is part of the phylum Euglenozoa. [3] The name is derived from the Ancient Greek trypano-(borer) and soma (body) because of their corkscrew-like motion.
