Plasmodium tenue
Encyclopedia
Plasmodium tenue is a parasite of the genus Plasmodium
.
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.Kawamoto F, Win TT, Mizuno S, Lin K, Kyaw O, Tantulart IS, Mason DP, Kimura M, Wongsrichanalai C. (2002) Unusual plasmodium malariae-like parasites in southeast Asia. J. Parasitol. 88(2):350-357
).
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.
It is a member of the subgenus Novyella
