| neoparamoeba perurans n. sp., an agent of amoebic gill disease of atlantic salmon (salmo salar). | amoebic gill disease (agd) is a potentially fatal disease of some marine fish. two amphizoic amoebae neoparamoeba pemaquidensis and neoparamoeba branchiphila have been cultured from agd-affected fish, yet it is not known if one or both are aetiological agents. here, we pcr amplified the 18s rrna gene of non-cultured, gill-derived (ncgd) amoebae from agd-affected atlantic salmon (salmo salar) using n. pemaquidensis and n. branchiphila-specific oligonucleotides. variability in pcr amplification le ... | 2007 | 17561022 |
