Septatorina
Septatorina is a suborder of parasitic alveolates of the phylum Apicomplexa Taxonomy There are five superfamilies and one family in this suborder: superfamilies ''Fusionicae'', ''Gregarinicae'', ''Porosporicae'', ''Stenophoricae'' and ''Stylocephaloidea''; and family ''Blabericolidae''. History This taxon was created in 1885 by Ray Lankester. Description The defining morphological feature of this taxon is the presence of septum dividing the gamont or trophozoite into a protomerite and deutomerite. The septum may not always be visible by light microscopy. Species in this taxon also have an epimerite. Species in this taxon infect invertebrates and especially arthropod Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arth ...s. References SAR supergroup suborders Conoidasi ...

Eugregarinorida
The ''Eugregarinorida'' are the most large and diverse order of gregarines — parasitic protists belonging to the phylum Apicomplexa. Eugregarines are found in marine, freshwater and terrestrial habitats. These species possess large trophozoites that are significantly different in morphology and behavior from the sporozoites. This taxon contains most of the known gregarine species. These protozoa are common parasites of many invertebrates including insects and polychete worms. Taxonomy Eugregarinorida has three recognised suborders: Aseptatorina, Blastogregarinorina and Septatorina. The intestinal eugregarines are separated into septate — suborder Septatina — and aseptate — suborder Aseptatina — depending on whether the trophozoite is superficially divided by a transverse septum. The marine gregarines are the most poorly studied members of this order. The eugregarines have been classified into 27 families with ~244 genera, 14 of which have more than 25 species each. ...

Stenophoricae
Stylocephaloidea is a superfamily of parasites of the phylum Apicomplexia. Taxonomy There are eleven families in this taxon. History This superfamily was created by Levine in 1984.Levine ND (1984) Nomenclatoral corrections and new taxa in the apicomplexan protozoa. Trans American MicroscSoc 103 :195—204 Its description was emended by Clopton in 2009. It was previously designated Solitaricae by Chakravarty in 1960. Description Species in this superfamily infect only a single host during their life cycle. The trophozoites are solitary and may develop either intracellularly or extracellularly. The epimerite varies in its structure between species. The gametocysts may or may not have sporoducts. They have a hyaline epicyst. Oocyst Apicomplexans, a group of intracellular parasites, have life cycle stages that allow them to survive the wide variety of environments they are exposed to during their complex life cycle.

Blabericolidae
''Blabericolidae'' is a family of parasitic alveolates in the phylum Apicomplexia. Taxonomy There are two genera in this family: '' Blabericola'' and '' Protomagalhaensia''.

Description Species in the family infect cockroach Cockroaches (or roaches) are a Paraphyly, paraphyletic group of insects belonging to Blattodea, containing all members of the group except termites. About 30 cockroach species out of 4,600 are associated with human habitats. Some species are we ...es. The type genus is '' Blabericola'', and the type species is '' Blabericola migrator''.

Stylocephaloidea
Stylocephaloidea is a superfamily of parasitic alveolates of the phylum Apicomplexia Taxonomy There are two families in this taxon. History This superfamily was established by Clopton in 2009. Description Species in this taxon infect insect Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs ...s. Syzygy is frontal or frontolateral. The gametocysts form an epicyst (ectocyst). The epicyst may rupture or dissolve. The sporocysts are released either singly or in chains. References Conoidasida SAR supergroup superfamilies {{Apicomplexa-stub ...

Gregarinasina
The gregarines are a group of Apicomplexan alveolates, classified as the Gregarinasina or Gregarinia. The large (roughly half a millimeter) parasites inhabit the intestines of many invertebrates. They are not found in any vertebrates. However, gregarines are closely related to both ''Toxoplasma'' and ''Plasmodium'', which cause toxoplasmosis and malaria, respectively. Both protists use protein complexes similar to those that are formed by the gregarines for gliding motility and invading target cells. This makes them excellent models for studying gliding motility with the goal of developing treatment options for toxoplasmosis and malaria. Thousands of different species of gregarines are expected to be found in insects, and 99% of these gregarines still need to be described. Each insect can be the host of multiple species. One of the most studied gregarines is ''Gregarina garnhami''. In general, gregarines are regarded as very successful parasites, as their hosts are spread over the ...

Gregarinicae
Gregarinicae is a superfamily of parasitic alveolates of the phylum Apicomplexia Taxonomy There are seven families in this taxon.

Porosporicae
Porosporidae is a family of parasitic alveolates of the phylum Apicomplexia Taxonomy This family has 3 genera - '' Pachyporospora'', '' Porospora'' and '' Nematopsis'' - and 37 species. The members of this family are distinguished from the other septate gregarines by having a digenic (two host) life cycle. History This taxon was created in 1899 by Labbé.Labbé A (1899) Sporozoa.

Friedländer und Sohn, Berlin: Germany Description The species in this family are heteroxenous Heteroxeny, or heteroxenous development, characterizes a parasite whose development involves several host species. Heteroxeny has been used as the basis for splitting genera. When there are two or three hosts, the development cycle is named di ..., meaning they live in two separate hosts during their life cycle.

Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invertebrate
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50 μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra'', whi ...
