Cyrilia is a genus of parasitic protozoa in the phylum Apicomplexia. The genus was created by Lainson in 1981. Species in this genus infect fresh water fish and are transmitted by leeches.

Life cycle

The parasites are transmitted to the vertebrate host by the bite of a leech.

The parasite undergoes merogony and gametogony in the fish erythrocytes.

The mature gametocytes are ingested by a leech and undergo fusion, sygyny, sporogony and merogony in the leech.

Each zygote undergoes multiple divisions producing 16–32 sporozoites which are infective for vertebrate host.

Sporogony occurs in the intestinal wall of the leech.

Each of the microgametocyes produce four microgametes each capable of fertilizing a macrogamete.
