During the years 2004 and 2005 high mortalities in turbot Scophthalmus maximus (L.) from a fish farm in the north of Portugal were observed. Moribund fish showed darkening of the ventral skin, reddening of the fin bases and distended abdominal cavities caused by the accumulation of ascitic fluid.

Pasteurella piscicida strains were weakly or moderately adherent to cell lines, the levels of attachment being variable depending on the cells employed. All the isolates exhibited the highest binding capacity to CHSE-214 cells. Adhesive capacities were affected by heat and sugars but not by proteinase K or by treatment with antisera raised against the lipopolysaccharides of P. piscicida, implic...
