Haemosporidia
Haemosporidiasina (Haemosporidia) is a subclass of apicomplexans described by Jacques Euzéby in 1988.Euzéby, J. (1988) Comparative Medical Protozoology, Vol. 3: Apicomplexa, 2: Haemosporidioses, Part 1: Plasmodiids, Haemoproteids, "Piroplasms" (general characters) The taxon is very similar to Aconoidasida.

Nycteria
''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 rather than a mosquito or the vector of most haemosporidian parasites. Etymology The word ''Nycteris'' is derived from the Greek word “nykteros”, also “bat”. ''Nycteris'' is a bat genus in the family ...

Haemoproteus
''Haemoproteus'' is a genus of alveolates that are parasitic in birds, reptiles and amphibians. Its name is derived from Greek: ''Haima'', "blood", and ''Proteus'', a sea god who had the power of assuming different shapes. The name ''Haemoproteus'' was first used in the description of '' H. columbae'' in the blood of the pigeon ''Columba livia'' by Kruse in 1890. This was also the first description of this genus. Two other genera — '' Halteridium'' and '' Simondia'' — are now considered to be synonyms of ''Haemoproteus''. The protozoa are intracellular parasites that infect the erythrocytes. They are transmitted by blood sucking insects including mosquitoes, biting midges (''Culicoides''), louse flies (''Hippoboscidae'') and horse-flies (" tabanids", "tabanid flies"). Infection with this genus is sometimes known as pseudomalaria because of the parasites' similarities with ''Plasmodium'' species. Within the genus there are at least 173 species, 5 varieties and 1 subspecies. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haemocystidium
''Haemocystidium'' is a genus of parasitic alveolates belonging to the phylum Apicomplexia. History The genus ''Haemocystidium'' was created to give a name to the haemoproteid of a gecko belonging to the genus '' Hemidactylus'' in Sri Lanka by Castellani and Willey in 1904. A second species in this genus was described in 1909 by Johnston and Cleland who found pigmented gametocytes in the blood of the Australian tortoise ''Chelodina longicollis''. These species were transferred to ''Haemoproteus'' in 1926 by Wenyon. The genus was resurrected by Garnham in 1966 when he created a new generic name - '' Simondia'' - for the haemoproteids of chelonians. He followed the opinions of Wenyon, Hewitt and DeGiusti and suggested that all these parasites belonged to the one species - '' Simondia metchnikovi''. He retained the name ''Haemocystidium'' for the haemoproteids of lizards. Levine and Campbell in 1971 moved all the species in ''Simondia'' and ''Haemocystidium'' into ''Haemoproteus'' ...

Apicomplexa
The Apicomplexa (also called Apicomplexia) are a large phylum of parasitic alveolates. Most of them possess a unique form of organelle that comprises a type of non-photosynthetic plastid called an apicoplast, and an apical complex structure. The organelle is an adaptation that the apicomplexan applies in penetration of a host cell. The Apicomplexa are unicellular and spore-forming. All species are obligate endoparasites of animals, except '' Nephromyces'', a symbiont in marine animals, originally classified as a chytrid fungus. Motile structures such as flagella or pseudopods are present only in certain gamete stages. The Apicomplexa are a diverse group that includes organisms such as the coccidia, gregarines, piroplasms, haemogregarines, and plasmodia. Diseases caused by Apicomplexa include: * Babesiosis (''Babesia'') * Malaria (''Plasmodium'') * Cryptosporidiosis (''Cryptosporidium parvum'') * Cyclosporiasis (''Cyclospora cayetanensis'') * Cystoisosporiasis (''Cystoisosp ...

Polychromophilus
The genus ''Polychromophilus'' consists of obligate intracellular eukaryotic Parasitism, parasites that infect bats from every continent except Antarctica. They are transmitted by bat flies, which act as an insect vector as well as the parasite’s site of Apicomplexan life cycle, sporogeny. ''Polychromophilus'' follows a fairly typical Haemosporida, Haemospororidian lifecycle, with gametocytes and gametes restricted to the bloodstream of the host and meronts infecting organs – most notably the lungs and the liver. The type species is ''Polychromophilus melanipherus'', and was described by Dionisi in 1898. Taxonomy ''Polychromophilus'' was first described by Dionisi in 1898, who also differentiated between the first two species, ''Polychromophilus murinus'' and ''Polychromophilus melanipherus''. Both of these original species were named after their primary hosts – ''Vespertilio murinus'' and ''Miniopterus schreibersi'' respectively. In 1906, Schingareff managed to observe and ...

Saurocytozoon
''Saurocytozoon'' is a genus of parasitic alveolates. They infect reptiles and are thought to be transmitted by mosquitoes. Only two species have been described to date. Their relationship with the other members of this order is not presently clear. Description Members of this genus infect reptiles. They do not produce pigment nor do they undergo Protozoal merogony, merogony in the blood. Schizonts are found in the tissues. Gametocytes are found in the peripheral blood. They infect the leukocytes and cause gross distortion of the host cell. The gametocytes are large and round.

Ettore Marchiafava
Ettore Marchiafava (3 January 1847 – 22 October 1935) was an Italian physician, pathologist and neurologist. He spent most of his career as professor of medicine at the University of Rome (now Sapienza Università di Roma). His works on malaria laid down the foundation for modern malariology. He and Angelo Celli were the first to elucidate living malarial parasites in human blood, and able to distinguish the protozoan parasites responsible for tertian and benign malaria. In 1885 they gave the formal scientific name ''Plasmodium'' for these parasites. They also discovered meningococcus as the causative agent of cerebral and spinal meningitis. Marchiafava was the first to describe syphilitic cerebral arteritis and degeneration of brain in an alcoholic patient, which is now eponymously named Marchiafava's disease. He gave a complete description of a genetic disease of blood now known Paroxysmal nocturnal hemoglobinuria or sometimes Strübing-Marchiafava-Micheli syndrome, in h ...

Eukaryota
Eukaryotes () are organisms whose Cell (biology), cells have a cell nucleus, nucleus. All animals, plants, fungi, and many unicellular organisms, are Eukaryotes. They belong to the group of organisms Eukaryota or Eukarya, which is one of the Three-domain system, three domains of life. Bacteria and Archaea (both prokaryotes) make up the other two domains. The eukaryotes are usually now regarded as having emerged in the Archaea or as a sister of the Asgard (archaea), Asgard archaea. This implies that there are only Two-domain system, two domains of life, Bacteria and Archaea, with eukaryotes incorporated among archaea. Eukaryotes represent a small minority of the number of organisms, but, due to their generally much larger size, their collective global biomass (ecology), biomass is estimated to be about equal to that of prokaryotes. Eukaryotes emerged approximately 2.3–1.8 billion years ago, during the Proterozoic eon, likely as Flagellated cell, flagellated phagotrophs. The ...

Vetufebrus
''Vetufebrus'' is an extinct genus of haemospororida in the family Plasmodiidae. At the time of its description the new genus comprised a single species ''Vetufebrus ovatus'' known from a single Miocene Dominican amber fossil found on Hispaniola. ''V. ovatus'' was vectored by ''Enischnomyia stegosoma'', the first fossil streblid bat fly described from a fossil, and the only member of the subfamily Nycterophiliinae described from Hispaniola. ''V. ovatus'' is the first instance of a Streblidae bat fly as a host for a malarial parasite. History and classification ''Vetufebrus ovatus'' was described based on a group of fossilized specimens which are preserved as in the host batfly, itself an Inclusion (mineral), inclusion in a transparent chunk of Dominican amber. The amber is fossil resin that was produced by the extinct ''Hymenaea protera'', which formerly grew on Hispaniola, across northern South America and up to southern Mexico. The amber dates from the Burdigalian stage (20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
