Nucleophaga is a genus of eukaryotic microorganisms that are internal parasites of amoeba, flagellates, and ciliates.[1][2]

Morphology and life cycle

Nucleophaga grows within the nucleus of its host cell.[3] Its spores are ingested by the host and migrate to the nucleus. Once in the nucleus, the spores germinate giving rise to naked plasmodia in contact with the host's karyoplasm. It develops pseudopodia-like projections that may be involved in osmotrophy or phagocytosis. The Nucleophaga cells continue to enlarge until a cell wall replaces the projections and the Nucleophaga cytoplasm is divided into spores.[4]

Taxonomy

Described by Dangeard in 1895, Nucleophaga was placed in Olpidiaceae, Chytridiales.[3][1] Molecular phylogenetic studies have placed some members in the Cryptomycota/Rozellomycota.[4][5]
