Chagasella is a genus of parasitic alveolates of the phylum Apicomplexa. Species in this genus infect insects of the order Hemiptera and of the family Termitoidae.
Two species are recognised in this genus.
The species in this genus are parasitic in arthropods.
These parasite appear to be spread via the orofaecal route and infect the gastrointestinal tract and salivary glands of the insect host. They form ovoid oocysts in the gut wall. There are three sporocysts per oocyte and 4-6 (possibly more) sporozoites per sporocyst. The merozoites are banana shaped. The spores are not confined by an oocyst membrane.
Gibbs in 1944 showed that after the first division of the zygote nucleus in the oocyst, only one of the two daughter nuclei divides. [1] This differential division, by analogy with Adelina deronis , may indicate maleness for the nucleus that divided and femaleness for the one that does not.
Trematoda is a class within the phylum Platyhelminthes. It includes two groups of parasitic flatworms, known as flukes.
Karyolysus is a genus of coccidia. With the exception of K. sonomae whose vertebrate host is the yellow-legged frog, species in this genus only infect lizards of the genus Lacerta.
The genus Polychromophilus consists of obligate intracellular eukaryotic 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 sporogeny. Polychromophilus follows a fairly typical 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.
Hoarella is a genus of parasitic alveolates in the phylum Apicomplexa. This genus infects reptiles.
Atoxoplasma is a genus of parasitic alveolates in the phylum Apicomplexa. The species in this genus infect birds. They are spread by the orofaecal route.
Barrouxia is a genus of parasitic alveolates belonging to the phylum Apicomplexa.
Defretinella is a genus of parasitic alveolates of the phylum Apicomplexa.
Gibbsia is a genus of parasitic alveolates of the phylum Apicomplexa.
Rasajeyna is a genus of parasitic alveolates in the phylum Apicomplexa. This genus has been little studied and not much is known about these protozoa.
Legerella is a genus of parasitic alveolates of the phylum Apicomplexa. Species in this genus that usually infect the malpighian tubules of invertebrates.
Klossiella is a genus of parasitic alveolates of the phylum Apicomplexa. Species in this genus infect the renal tract of mammals and intestinal tract of snakes.
Hyaloklossia is a genus of parasitic alveolates in the phylum Apicomplexa. Only one species in this genus is currently recognised - Hyaloklossia lieberkuehni.
Sivatoshella is a genus of parasitic alveolates in the phylum Apicomplexa.
Pfeifferinella is a genus of parasitic alveolates in the phylum Apicomplexa. This genus has been poorly studied and little is known about it. Species in this genus infect marine priapulid worms and terrestrial and freshwater gastropods.
The Syncystidae are a family of parasitic alveolates in the phylum Apicomplexa. Species in this family infect insects (Aeshnidae).
The Schizocystidae are a family of parasitic alveolates in the phylum Apicomplexa. Species in this family infect insects.
Farinocystis is a genus of parasitic alveolates of the phylum Apicomplexa. Species in this genus infect insects (Coleoptera).
Cystoisospora belli, previously known as Isospora belli, is a parasite that causes an intestinal disease known as cystoisosporiasis. This protozoan parasite is opportunistic in immune suppressed human hosts. It primarily exists in the epithelial cells of the small intestine, and develops in the cell cytoplasm. The distribution of this coccidian parasite is cosmopolitan, but is mainly found in tropical and subtropical areas of the world such as the Caribbean, Central and S. America, India, Africa, and S.E. Asia. In the U.S., it is usually associated with HIV infection and institutional living.
