Mesnilium is a genus of parasitic alveolates belonging to the phylum Apicomplexa. Its vertebrate hosts are fish. The vectors are not presently known but are thought likely to be leeches.

Contents

Taxonomy

The genus was created in 1972 by Misra, Haldar and Chakravarty. [1]

Description

Merogony occurs in erythrocytes and reticulo-endothelial cells. Gamogony occurs only in erythrocytes and pigment granules are present only in microgamonts and macrogametes.

Hosts

The only known host of this parasite is the freshwater murrel ( Ophicephalus punctatus ).

<i>Bartonella</i> Genus of bacteria

Bartonella is a genus of Gram-negative bacteria. It is the only genus in the family Bartonellaceae. Facultative intracellular parasites, Bartonella species can infect healthy people, but are considered especially important as opportunistic pathogens. Bartonella species are transmitted by vectors such as fleas, sand flies, and mosquitoes. At least eight Bartonella species or subspecies are known to infect humans.

<i>Hepatozoon</i> Genus of single-celled organisms

Hepatozoon is a genus of Apicomplexa alveolates which incorporates over 300 species of obligate intraerythrocytic parasites. Species have been described from all groups of tetrapod vertebrates, as well as a wide range of haematophagous arthropods, which serve as both the vectors and definitive hosts of the parasite. By far the most biodiverse and prevalent of all haemogregarines, the genus is distinguished by its unique reciprocal trophic lifecycle which lacks the salivary transmission between hosts commonly associated with other apicomplexans. While particularly prevalent in amphibians and reptiles, the genus is more well known in veterinary circles for causing a tick-borne disease called hepatozoonosis in some mammals.

It is found in the western Indian Ocean off the coasts of Natal, South Africa, southern Mozambique, Madagascar, Kenya, and Tanzania between latitudes 4° S and 37° S, at depths of between 220 and 440 m. It can grow up to 35 cm in length.

<i>Haemoproteus</i> Genus of single-celled organisms

Haemoproteus is a genus of alveolates that are parasitic in birds, reptiles, and amphibians. Its name is derived from Greek: haima 'blood' and Proteus, a sea god that had the power to assume various shapes. The name Haemoproteus was first used in the description of H. columbae in the blood of the pigeon Columba livia by Walther Kruse in 1890. This was also the first description of this genus. Two other genera—Halteridium and Simondia—are now considered to be synonyms of Haemoproteus.
