Progarnia archosauriae
Progarnia archosauriae is a blood parasite belonging to the phylum Apicomplexa, family Garniidae. It was first described in the spectacled caiman, a member of Archosauria: Crocodilia. The parasite undergoes merogony and gametogony primarily in leukocytes and thrombocytes, occasionally invading erythrocytes without producing malarial pigment. Its characteristics suggest evolutionary links between reptilian and avian haemosporines.
