  • 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, implicating components of glycoprotein(s) as ligands in the adhesion process. The isolates showed a great binding capacity to intestines from the marine fish hosts gilthead sea bream, sea bass and turbot, with values ranging from 10(4) to 10(5) bacteria/g. Although the P. piscicida strains showed a weak invasiveness in the poikilothermic cell lines employed as in vitro model, the bacteria remained viable inside the infected cells at least for 2 days. The invasion process was inhibited by cytochalasin D indicating the active participation of the host cell cytoskeleton in the internalization of P. piscicida.
