The flowing amoeba ( Vahlkampfia ) are a protozoa genus from the group of the Heterolobosea .

features

In contrast to most Heterolobosea, a flagellated stage is missing in the life cycle of the flow amoeba, nor do they form fruiting bodies. The amoeba always have only one nucleus . The cysts can have a gelatinous covering, pores for the excystation are almost always missing.

Way of life

Flow amoeba feed on bacteria , blue-green algae and organic sludge components, which they absorb into the cell after flowing around.

Systematics

For a long time, the genus was considered to be extremely species-rich, but many species did not belong to the genus, particularly on the basis of molecular biological studies of the rDNA. Some species were transferred to new genera ( Paravahlkampfia , Neovahlkampfia ), others now belong to the genus Tetramitus . The remaining five types are:
