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]
