Plasmodium tenue is a parasite of the genus Plasmodium subgenus Novyella .

Contents

This species is unusual in that the same specific name was used in two distinct papers published in the same year. It is currently thought that the species description by Stephens in man is likely to have been an artifact and that the accepted valid species is the one described from birds.

This name still occurs in the literature for species found in humans that look atypical. [1] It is a member of the subgenus Novyella .

Further adding to the confusion concerning this species, it is sometimes referred to as Plasmodium tenuis

Taxonomy

This species was first described by Stephens in 1914. [2] The same name was used by Laveran and Marullaz also in 1914 [3] which described this species in a babbler ( Leiothrix lutea ).

Description

The bird species usually produces 4 merozoites per segmenter, but often as many as 6; rarely it gives rise to only 2 - 3. The gametocytes are elongate. Neither sexual nor asexual stages displace the host cell nucleus.

Hosts

The known hosts of this species include the babblers Leiothrix lutea and Garrulax canorus taewanus .

<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 red-billed leiothrix is a member of the family Leiothrichidae, native to southern China and the Himalayas. Adults have bright red bills and a dull yellow ring around their eyes. Their backs are dull olive green, and they have a bright yellow-orange throat with a yellow chin; females are somewhat duller than males, and juveniles have black bills. It has also been introduced in various parts of the world, with small populations of escapees having existed in Japan since the 1980s. It has become a common cagebird and amongst aviculturists it goes by various names: Pekin robin, Pekin nightingale, Japanese nightingale, and Japanese (hill) robin, the last two being misnomers as it is not native to Japan.
