''Ophidiella'' is a subgenus of the genus ''Plasmodium'' created in 1966 by Garnham.Garnham P.C.C. (1966) Malaria Parasites and Other Haemosporidia. Oxford, Blackwell It was created as a subgenus for the then only known species infecting snake Snakes are elongated, limbless, carnivorous reptiles of the suborder Serpentes .

Plasmodium
''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 (often the liver) 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 (mosquitoes in majority cases), continuing the life cycle. ''Plasmodium'' is a member of the phylum Apicomplexa, a large group of parasitic eukaryotes. Within Apicomplexa, ''Plasmodium'' is in the order Haemosporida and family Plasmodiidae. Over 200 species of ''Plasmodium'' have been described, many of which have been subdivided into 14 subgenera based on parasite morphology and host range.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Percy Cyril Claude Garnham
Percy Cyril Claude Garnham CMG FRS (15 January 1901 – 25 December 1994), was a British biologist and parasitologist. On his 90th birthday, he was called the "greatest living parasitologist". Early life and education Garnham was born in London, the son of Percy Claude Garnham (1875–1915), and Edith née Masham (1878–1951), an accomplished violinist. In World War I, his father served as a lieutenant in the Royal Navy and died at Gallipoli in 1915. He was educated at Paradise School and St Bartholomew's Hospital, London, and graduated in medicine in 1925. followed by a diploma in public health. In 1928 he was awarded an MD degree by the University of London for his work on malaria in Kenya and also a Gold Medal. Career Garnham's career started in 1925 as a member of the British Colonial Medical Service in Kenya. This introduced him to a very wide range of tropical diseases of humans and animals and their vectors as he worked on identification and control. It also brough ...

Snake
Snakes are elongated, Limbless vertebrate, limbless, carnivore, carnivorous reptiles of the suborder Serpentes . Like all other Squamata, squamates, snakes are ectothermic, amniote vertebrates covered in overlapping Scale (zoology), scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads (cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have evolved elongate bodies without limbs or with greatly reduced limbs about twenty-five times independently via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, altho ...

Plasmodium Wenyoni
''Plasmodium wenyoni'' is a parasite of the genus ''Plasmodium''. As in all ''Plasmodium'' species, ''P. wenyoni'' has both vertebrate and insect hosts. The vertebrate hosts for this parasite are reptiles. Taxonomy The parasite was first described by Garnham in 1965.Garnham P.C. (1965) ''Plasmodium wenyoni'' sp. nov., a malaria parasite of a Brazilian snake. Trans R Soc Trop Med Hyg. 59:277-279 The original host was a '' Thamnodynastes pallidus'' that died in a London zoo in 1934. Distribution This species is found in Brazil. Hosts The only known hosts of this species are snakes. The insect vectors for this species are mosquitoes of the genus ''Culex ''Culex'' is a genus of mosquitoes, several species of which serve as vectors of one or more important diseases of birds, humans, and other animals.

Plasmodium Pessoai
''Plasmodium pessoai'' is a parasite of the genus ''Plasmodium''. As in all ''Plasmodium'' species, ''P. pessoai'' has both vertebrate and insect hosts. The vertebrate hosts for this parasite are reptiles. Taxonomy The parasite was first described by Ayala ''et al.'' in 1978.Ayala S.C., Moreno-Robles E., Bolaños-Herrera, R. (1978) ''Plasmodium pessoai'' sp. n. procedentes de dos serpientes costarricenses. J. Parasitol. 64(2)330-335 The species is named after Dr Samuel B Pessoa - a parasitologist at the Instituto Butantan, São Paulo, Brazil. Morphologically this species appears to be related to '' Plasmodium aurulentum''. Description The gametocytes are small and sausage shaped (10.4 x 4.6 micrometres) Immature schizonts often contain a digestive vacuole. Mature schizonts are spherical or bouquet-shaped and produce 22 - 32 merozoites. They may possess an intensely staining magenta or rose-coloured substance in the matrix of the surrounding vacuole.
