[This organism requires further investigation.]
Family. Bodonidæ, Bütschli.
Protomonadina which are either free-living or parasitic, with two dissimilar flagella, while the possession of an undulating membrane and of a kinetic nucleus or blepharoplast is variable.
There are three genera:—
1. Bodo, Stein, 1878, without a kinetic nucleus and undulating membrane.
2. Prowazekia, Hartmann and Chagas, 1910, with a kinetic
nucleus and without an undulating membrane.
3. Trypanoplasma, Laveran and Mesnil, 1901, with a kinetic
nucleus and undulating membrane.
Of these genera Prowazekia must be discussed. Bodo does not occur in man. Species of Trypanoplasma occur in the blood and in the gut of various fishes, in the seminal receptacle of certain snails, in the gut and genitalia of a flatworm (Dendrocœlum lacteum) and in the vagina of a leech. Closely allied to Trypanoplasma is the genus Trypanophis, parasitic in the cœlenteric cavity of Siphonophores.
Genus. Prowazekia, Hartmann and Chagas, 1910.
