Exoschizon is a genus in the phylum Apicomplexa.

History

This genus was created by Levine in 1971. [1]

Taxonomy

There is one genus currently recognised in this family - Exoschizon. This genus has only one species - Exoschizon siphonosomae - which was described by Hukui in 1939. [2]

Description

This species was found in the intestine of a sipunculid worm ( Siphonosoma cumanense ) in Japan.

The meronts measure 90 µm × 15 µm. There are ~13 longitudinal striations per side.

The meronts and gamonts are similarly shaped.

Transmission is presumably by the orofaecal route.

The Apicomplexa 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.

Acroeimeria is a genus of parasites that contains those species which initially develop immediately beneath the brush-border of the intestinal epithelium, but the meronts and gamonts of which are early on extruded to form a layer on the surface of the gut mucosa. Morphologically they are similar to the Eimeria to which they are closely related. The genus was described in 1989 by Paperna and Landsberg.

The genus Schellackia comprises obligate unicellular eukaryotic parasites within the phylum Apicomplexa, and infects numerous species of lizards and amphibians worldwide. Schellackia is transmitted via insect vectors, primarily mites and mosquitoes, which take up the parasite in blood meals. These vectors then subsequently infect reptilian and amphibian which consume the infected insects. The parasites deform erythrocytes of the host into crescents, and can be visualised using a blood smear.

Species in this order infect insects and are usually found in the fat body, hemolymph, hypodermis, intestine or Malpighian tubules. The most common site of infection is the fat body: many species are pathogenic for their hosts.
