Abstract

Larsen J.L. and K. Pedersen: Atypical Aeromonas salmonicida isolated from dis-eased torbut (Scophtalmus maximus L.). Acta vet. scand. 1996, 37, 139-146. - Atyp-ical Aeromonas salmonicida were isolated from 3 outbreaks of disease among farmed turbot (Scophthalmus maximus L.) in 3 different farms, 1 from Norway (Nl) and 2 from Denmark (DK1 and DK2). In all 3 cases, the incidence of disease and mortality was high and the main characteristic pathological finding was skin ulcers and septicaemia. The isolated bacteria were subjected to a thorough phenotypic and genotypic examination and comparison in the laboratory. All 3 isolates belonged to A. salmonicida but dis-played some very different biochemical properties. However, the 2 Danish strains, DK1 and DK2 had identical ribotypes but different from that of Nl, whereas the plasmid pro-files of DK1 and Nl were identical but different from that of DK2. These observations emphasize the need for an improvement of our understanding of the taxonomy and epi-demiology of atypical A. salmonicida.
