''Babesiosoma'' is a genus of parasitic protozoa in the phylum Apicomplexia. They have two hosts in their life cycle: the vertebrate hosts are fish and the invertebrate vectors are leeches. This genus has been poorly studied and little is known about it. ==History== The genus was created in 1956 by Jakowski and Nigrelli.〔Jakowska S, Nigrelli RF (1956)Some protozoan diseases of man and animals: Anaplasmosis, Babesiosis, and Toxoplasmosis. Annal NY Acad Sci 64, 112–127〕 Seven species have been recognised in this genus.〔Misra KK, Haldar DP, Chakravarty MM (1969) ''Babesiosoma ophicephali'' n. sp. from the freshwater teleost ''Ophicephalus punctatus'' Bloch. J Protozool 16(3):446-449〕〔Negm-Eldin MM (1998) Life cycle, host restriction and longevity of ''Babesiosoma mariae'' HOARE, 1930 (Apicomplexa: Dactylosomatidae). Dtsch Tierarztl Wochenschr 105(10):367-374〕〔Smit NJ, Van As JG, Davies AJ (2003) Observations on ''Babesiosoma mariae'' (Apicomplexa: Dactylosomatidae) from the Okavango Delta, Botswana.

Gametocytes: These are larger and more elongated than the meronts and are generally club-shaped. 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「Babesiosoma」の詳細全文を読む スポンサード リンク
