Also Known As: '''''AGD — Amoebiasis — Amoebic Gill Infection — Amoebosis — Paramoebiasis'''''
Also Known As: '''''AGD — Amoebiasis — Amoebic Gill Infection — Amoebosis — Paramoebiasis'''''
Caused By: '''''Neoparamoeba pemaguidensis'''''
Caused By: '''''Neoparamoeba pemaguidensis — Neoparamoeba perurans'''''
==Introduction==
==Introduction==
Amoebic gill disease is caused by '''''Neoparamoeba pemaguidensis''''', the '''most important pathogenic amoeba in fish'''. The disease causes large economic losses in '''marine cultured salmonids'''.<ref> Munday, B. L., Zilberg, D., Findlay, V (2001) '''Gill disease of marine fish caused by infection with ''Neoparamoeba pemaquidensis'''''. ''J Fish Diseases'', 24(9):497-507</ref> It can also affect turbots.

Neoparamoeba perurans, a newly described amoeba is also known to colonize fish gills which results in amoebic gill disease in salmonids <ref name="Young">Young, N.D. Crosbie, P.B.B., Adams, M.B., Nowak, B.F., and Morrison R.N. (2007) '''''Neoparamoebae perurans'' n.sp., an agent of amoebic gill disease in Atlantic salmon (Salmo salar).''' ''International Journal of Parasitology'' 37, 1469-1481.</ref>. More careful comparative field (e.g. susceptibility of different fish species under various environmental conditions) and laboratory studies (e.g. biochemical, molecular) using cloned isolates of the two species are required to more clearly determine the etiological agent(s) of AGD.

The amoeba will also readily colonise severe injuries such as jellyfish stings, clubbed lamellae and necrotic gill syndrome lesions.
The amoeba will also readily colonise severe injuries such as jellyfish stings, clubbed lamellae and necrotic gill syndrome lesions.
Clinical AGD is always associated with '''water temperatures of 12-20⁰ and high salinities of ≥32 ppt'''. <ref> Rodger, H. D., McArdle, J. F (1996) '''An outbreak of amoebic gill disease in Ireland'''. ''Veterinary Record'', 139(14):348-349</ref> Amoeba numbers also rise in the Summer.
