Giovanolaia is a subgenus of the genus Plasmodium created by Corradetti et al. in 1963. [1] [2] The parasites within this subgenus infect birds.

Contents

This subgenus was shown on the basis of DNA analysis to be polyphyletic. This is unsurprising – it has been a wastebasket taxon. A revision of this subgenus on a morphological basis by Landau et al. moved several of the species in this subgenus into a new subgenus Papernaia . [2]

Description

Species in the subgenus Giovanolaia have the following characteristics:

Schizonts contain plentiful cytoplasm, are larger than the host cell nucleus and frequently displace it. They are found only in mature erythrocytes.

Gametocytes are elongated.

Both gametocytes and schizonts are stretched along the red cell nucleus.

Exoerythrocytic schizogony occurs in the mononuclear phagocyte system.

<i>Plasmodium</i> Genus of parasitic protists that can cause malaria

Plasmodium is a genus of unicellular eukaryotes that are obligate parasites of vertebrates and insects. The life cycles of Plasmodium species involve development in a blood-feeding insect host which then injects parasites into a vertebrate host during a blood meal. Parasites grow within a vertebrate body tissue before entering the bloodstream to infect red blood cells. The ensuing destruction of host red blood cells can result in malaria. During this infection, some parasites are picked up by a blood-feeding insect, continuing the life cycle.

The genus Polychromophilus consists of obligate intracellular eukaryotic parasites that infect bats from every continent except Antarctica. They are transmitted by bat flies, which act as an insect vector as well as the parasite’s site of sporogeny. Polychromophilus follows a fairly typical Haemospororidian lifecycle, with gametocytes and gametes restricted to the bloodstream of the host and meronts infecting organs – most notably the lungs and the liver. The type species is Polychromophilus melanipherus, and was described by Dionisi in 1898.
