Protacanthamoeba is a genus of free-living naked amoebae of the family Acanthamoebidae described in 1981.^[1] It has been found in associations with mycobacteria in drinking water networks, along with other Acanthamoebidae genera, likely allowing the replication of both environmental and pathogenic mycobacteria.^[2]

Morphology

Members of Protacanthamoeba are characterized by having slender, flexible and sometimes furcate subpseudopodia originated from a broad, hyaline lobose pseudopodium, as well as having centrospheres in its interior, including a plaque-shaped centriole-like body. Their cysts lack preformed pores or opercula.^[3]

Taxonomy

Protacanthamoeba contains 3 species:

Protacanthamoeba bohemica Dyková et al. 2005^[4]
Protacanthamoeba caledonica Page 1981^[3]
Protacanthamoeba invadens (Singh & Hanumaiah 1979) Page 1981 (previously Acanthamoeba)^[3]
