How to Develop and Organize a Classification Essay.

Gregarina cuneata, Gregarina polymorpha, and Gregarina steini are characteristic parasites of larval T. molitor. Gregarina niphandrodes is a characteristic parasite of adult T. molitor.

The truth about in vitro culture of Cryptosporidium species.. (2014) provided the revision of gregarine higher classification. and the evolutionary diversification of Sporozoa using the gregar-.

The eugregarines are a group of apicomplexan parasites that mostly infect the intestines of invertebrates. The high level of morphological variation found within and among species of eugregarines makes it difficult to find consistent and reliable traits that unite even closely related lineages.

Classification of marine gregarines is often based on the morphological traits of the conspicuous feeding stages (trophozoites) in combination with host affiliation and molecular phylogenetic data. Morphological characters of other life stages such as the spore are also used to inform taxonomy when such stages can be found.

Ctenolepisma longicaudata, generally known as the gray silverfish, long-tailed silverfish or paper silverfish, is a species of Zygentoma in the family Lepismatidae.It was described by the German entomologist Karl Leopold Escherich in 1905 based on specimens collected in South Africa. In recent years, gray silverfish have increasingly become an issue in indoor environments in Europe.

The 'eugregarines' include the majority of gregarines (at least, the majority of described gregarines), and include parasites of freshwater and terrestrial as well as marine invertebrates. Again, their study has been biased towards those species that are parasites of insects, with the remainder being generally snubbed.

Both gregarine and water mite prevalences had a weak phylogenetic signal, and interestingly there was a positive correlation between gregarine and water mite prevalences. Even though encapsulation response showed only a weak phylogenetic signal, it may be strong enough to explain a certain degree of variation in gregarine and water mite prevalences.

Parasite definition, an organism that lives on or in an organism of another species, known as the host, from the body of which it obtains nutriment. See more.

Gregarine, any protozoan of the sporozoan class Gregarinidea (or Gregarinea). Gregarines occur as parasites in the body cavities and the digestive systems of invertebrates. Representative genera are Monocystis in earthworms and Gregarina in locusts and cockroaches. Long and wormlike, gregarines may reach a length of 10 mm (0.4 inch).
