Plasmodium lemuris is a parasite of the genus Plasmodium subgenus Vinckeia .

Contents

Like all Plasmodium species P. lemuris has both vertebrate and insect hosts. The vertebrate hosts for this parasite are mammals.

Taxonomy

This species was first described by Huff and Hoogstraal in 1963 in the black lemur Lemur collaris. [1] This species may belong to the genus Haemoproteus rather than to Plasmodium . Clarification of this point awaits examination of the organism's DNA.

Distribution

This species is found in Madagascar.

Hosts

The known hosts include the lemurs Lemur macaco macaco and Lemur collaris .

The infected erythrocyte is enlarged (+/- 10 micrometres) and distorted in shape and in many instances is almost completely filled by the parasite.

Young trophozoites are small and occupy three-tenths to four-tenths of the erythrocytes. The nucleus stains rose-red. Larger trophozoites are more irregular tending toward amoeboidity.

Pigment is in granules and there is no stippling of the host cell.

The schizonts display irregularly shaped nuclei. The pigment is brown and clumped into a diffused mass.

The gametocytes are very large (11×7 micrometres) and irregular in shape. Their nuclei are band-like or lobed irregularly.

The macrogametocytes have lavender to purple cytoplasm. The pigment is made up of small dark brown granules within vacuoles.

The microgametocytes have red-staining nuclei and slate-gray cytoplasm. Their pigment is similar to that of the macrogametocytes.

Nycteria is a genus of protozoan parasites that belong to the phylum Apicomplexa. It is composed of vector-borne haemosporidian parasites that infect a wide range of mammals such as primates, rodents and bats. Its vertebrate hosts are bats. First described by Garnham and Heisch in 1953, Nycteria is mostly found in bat species where it feeds off the blood of their hosts and causes disease. Within the host, Nycteria develops into peculiar lobulated schizonts in parenchyma cells of the liver, similarly to the stages of Plasmodium falciparum in the liver. The vector of Nycteria has been hard to acquire and identify. Because of this, the life cycle of Nycteria still remains unknown and understudied. It has been suggested that this vector could be an arthropod other than a mosquito or the vector of most haemosporidian parasites.
