Elleipsisoma is a genus of parasitic protozoa within the phylum Apicomplexia.

History

This parasite was described in 1912 by Franca. This genus may have been described earlier by Graham-Smith[1]

The type species is Elleipsisoma thomsoni

Hosts

This parasite infects the European mole (Talpa europaea). It is most commonly found in the heart and lungs. It may occasionally be found in the kidneys, liver and spleen.

Geographical distribution

This parasite is found in the United Kingdom.

Description

Parasitized red cells were larger than normal mature erythrocytes

Electron microscopic studies have shown the presence of rhoptries, micronemes, polar ring, microtubules and a conoid.[2]

Vectors
