Genus

Exoschizon

The Exoschizonidae are a family in the phylum Apicomplexa.

History

This family was created by Levine in 1971.[1]

Taxonomy

There is one genus currently recognised in this family - Exoschizon. This genus has only one species - Exoschizon siphonosomae - which was described by Hukui in 1939.[2]

Description

This species was found in the intestine of a sipunculid worm (Siphonosoma cumanense) in Japan.

The meronts measure 90 µm × 15 µm. There are ~13 longitudinal striations per side.

The meronts and gamonts are similarly shaped.

Transmission is presumably by the orofaecal route.
