The Neogregarinorida are an order of parasitic protozoa in the phylum Apicomplexa. Species in this order infect insects are usually found in the fat body, hemolymph, hypodermis, intestine or Malpighian tubules. The most common site of infection is the fat body: many species are pathogenic for their hosts. The species in this order are predominantly intracellular parasites. ==Taxonomy== Six families are in this order, with 13 genera. The type genus is ''Ophryocystis''. Two families (Ophryocystidae and Schizocystidae) belong to the suborder Schizogregarinina. They appear to have evolved from the Eugregarinorida. Merogony as part of the life cycle separates them from the Eugregarinorida and appears to have been derived as a secondary characteristic. A phylogenetic analysis of the small subunit RNA suggests ''Ophryocystis'' may actually be a eugregarine rather than a neogregarine. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Neogregarinorida」の詳細全文を読む スポンサード リンク
