Plasmodium alaudae is a parasite of the genus Plasmodium .

Description

The species was originally described by Celli & Sanfelice in 1891 as Haemoproteus alaudae, and it was first discovered in the blood of the skylark. The species was later transferred to the genus Plasmodium. On reexamination the described species was found to include members of at least one additional species and it was redescribed by Paperna et al. in 2009.^[1]

Trophozoites: the parasites are small and are located at ends of the erythrocyte. The erythrocyte nucleus is minimally displaced if at all.

Schizonts: these are rounded with clear cytoplasm and have 8 nuclei. There are a few vacuoles and two granules of pigment.

Gametocytes: these have not been described.

Differential diagnosis

The species must be differentiated from Plasmodium ashfordi , Plasmodium caloti and Plasmodium vaughani merulae .

Plasmodium ashfordi produces 7–8 merozoites per schizont but P. alaudae lacks the fan shaped schizonts found in P. ashfordi.

Plasmodium caloti is unique among the species with 8–10 merozoites per schizont infecting the skylark ( Alauda arvensis ) in the enlargement of the erythrocyte that it causes.

Although P. vaughani may also produce 8 merozoites per schizont, it possesses a bluish refractile globule that is not found in P. alaudae.

Geographical occurrence

The parasite is found in France and Italy.

Vectors

Not known.

Clinical features and host pathology

Plasmodium alaudae infects the magpie ( Pica pica ) - the type host - and the skylark ( Alauda arvensis ).

<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.
