Mattesia is a genus of parasitic alveolates of the phylum Apicomplexa. Species in this genus infect insects (Coleoptera, Hymenoptera, Lepidoptera and Siphonaptera).
The genus was created in 1930 by Naville.
There are eight recognised species in this genus.
The type species is Mattesia geminata.
The species in this genus are spread by the orofaecal route. They infect the fat bodies of species of Coleoptera, Hymenoptera, Lepidoptera and Siphonaptera, the hypodermis of species of Hymenoptera and the Malpighian tubules of species of Lepidoptera and Siphonaptera as well as intestine of one species of Lepidoptera.
The sporozoites are elongated and measure ~7 µm × 3 µm. They escape from oocyst while in gut lumen when polar plugs dissolve.
Flexing by the sporozoites generates motility. This permits them to penetrate the gut wall and migrate to the body fat where they enter cells of the adipose tissue. An apical complex appears to be present in sporozoites, merozoites and gamonts.
The meronts are found in a parasitophorous vacuole where they initially undergo micronuclear merogony by budding from the surface of the meront. The resulting merozoites spread the infection in the body fat, followed by macronuclear merogony.
