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.

The type species is Klossiella muris.

History

The first member of this genus was identified by Smith in 1889 in the kidney of a white mouse. An expanded study of this parasite was later published by Smith and Johnson in 1902 where they suggested the name Klossiella muris. [1]

Taxonomy

Currently there are 17 species recognised in this genus. All except one (Klossiella boae) infect the renal tracts of mammals.

Description

This genus is unusual in having only a single host in its life cycle.

The parasite is ingested and within the gut sporozoites escape from the sporocyst and invade the blood stream. Upon reaching the kidney, within the epithelium of the kidney the sporozoite undergoes merogony followed by gametogony and sporogony. It produces polysporocystic oocysts without a resistant oocyst wall. The resistant sporocysts are then shed in the urine.

The oocysts are subspherical, smooth and measure 22-24  μm by 20-21 μm.

Clinical

K. boae occurs both in the intestine and the kidney of the boa constrictor. [2] It may cause anorexia, restlessness, hemorrhagic enteritis and intussusception.

Host records

Note

This genus has also been found in the kidneys of bats but the species was not identified. [4]

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 visualized using a blood smear.
