Percolozoa

The Percolozoa are a group of colourless, non-photosynthetic protozoa, including many that can transform between amoeboid, flagellate, and cyst stages.

Terminology and classification

These are collectively referred to as schizopyrenids, amoeboflagellates, or vahlkampfids. They also include the acrasids, a group of social amoebae that aggregate to form sporangia. The entire group is usually called the Heterolobosea, but this may be restricted to members with amoeboid stages.

One Heterolobosea classification system is:

Order Schizopyrenida

Family Vahlkampfiidae
Family Gruberellidae

Family Vahlkampfiidae

Family Gruberellidae

Order Acrasida

Family Acrasidae

Family Acrasidae

Pleurostomum flabellatum has recently been added to Heterolobosea.

Characteristics

Most Percolozoa are found as bacterivores in soil, fresh water and occasionally in the ocean. The only member of this group that is infectious to humans is Naegleria fowleri, the causative agent of the often fatal disease amoebic meningitis. The group is closely related to the Euglenozoa, and share with them the unusual characteristic of having mitochondria with discoid cristae. The presence of a ventral feeding groove in the flagellate stage, as well as other features, suggests that they are part of the excavate group.

Never Coming Down

Yeah, yeah, yeah
Yeah, yeah, yeah, yeah
Come here yeah
Something in your eyes
Draws me in each and every time
Losing focus
