Acanthamoebidae

Cyst of Acanthamoeba polyphaga

The Centramoebida are amoeboid protozoa from the group of Amoebozoa. Some species are pathogenic in humans as in some animals.

Features

The single-celled organisms have a flattened body shape. They have moving pseudopods, called sub- pseudopodia, which are sometimes forked at the base, gradually tapering to a fine tip. The Uroid is not adherent. The cytoplasmic MTOC is three-lobed.

In a culture of the species appears to be branched, flat film, the Subpseudopodien missing. At least one type is Sporokarpe and is protosteloid, so resembles members of the genus Protostelium.

Species

In the plant species of the following genera Centramoebida be classified:

• Acanthamoeba (synonym Comandonia Pernin & Pussard 1979)
• Balamuthia
• Protacanthamoeba

Incertae sedis is listed as within the Centramoebida as a sister of Protacanthamoeba an undescribed species protosteloide ( LHI05 ). Also, two types of which are previously assigned to the genus Protostelium, namely Protostelium arachisporum and Protostelium pyriformis, may be placed in the Centramoebida.

Medical importance

Some species can cause diseases such as opportunists who Acanthamöbiasis as corneal inflammation or granulomatous amoebic encephalitis in animals and in humans.

The German Society for Protozoology, the genus Acanthamoeba protozoa for the year 2012 awarded.
