  <dc:description>&lt;p&gt;&lt;span&gt;A model system was used to study bacterial fish pathogen transmission between the freshwater bivalve&amp;nbsp;&lt;/span&gt;&lt;i&gt;Amblema plicata&lt;/i&gt;&lt;span&gt;&amp;nbsp;and two strains (Nauyuk and Labrador) of Arctic char&amp;nbsp;&lt;/span&gt;&lt;i&gt;Salvelinus alpinus. Aeromonas salmonicida&lt;/i&gt;&lt;span&gt;, the cause of fish furunculosis, was readily transmitted from Arctic char to&amp;nbsp;&lt;/span&gt;&lt;i&gt;A. plicata&lt;/i&gt;&lt;span&gt;&amp;nbsp;and vice versa via simple cohabitation. Clinical furunculosis was artificially established in Nauyuk Arctic char via horizontal exposure to Labrador Arctic char that received intraperitoneal injections of&amp;nbsp;&lt;/span&gt;&lt;i&gt;A. salmonicida.&lt;/i&gt;&lt;span&gt;&amp;nbsp;After the Nauyuk Arctic char began to die,&amp;nbsp;&lt;/span&gt;&lt;i&gt;A. plicata&lt;/i&gt;&lt;span&gt;&amp;nbsp;were placed in the tank with the fish. After 33 d of cohabitation, a group of 10&amp;nbsp;&lt;/span&gt;&lt;i&gt;A. plicata&lt;/i&gt;&lt;span&gt;&amp;nbsp;was cultured, and&amp;nbsp;&lt;/span&gt;&lt;i&gt;A. salmonicida&lt;/i&gt;&lt;span&gt;&amp;nbsp;was isolated from all 10. The remaining&amp;nbsp;&lt;/span&gt;&lt;i&gt;A. plicata&lt;/i&gt;&lt;span&gt;&amp;nbsp;were transferred to other tanks being supplied with specific-pathogen-free water. At 1, 5, 15, and 30 d after transfer, 60 uninfected Labrador Arctic char were cohabitated with the&amp;nbsp;&lt;/span&gt;&lt;i&gt;A. plicata.&lt;/i&gt;&lt;span&gt;&amp;nbsp;Transmission of&amp;nbsp;&lt;/span&gt;&lt;i&gt;A. salmonicida&lt;/i&gt;&lt;span&gt;&amp;nbsp;from&amp;nbsp;&lt;/span&gt;&lt;i&gt;A. plicata&lt;/i&gt;&lt;span&gt;&amp;nbsp;to the Arctic char was evaluated via fish mortality and bacterial culture after 3–4 weeks of exposure. Mortality to&amp;nbsp;&lt;/span&gt;&lt;i&gt;A. salmonicida&lt;/i&gt;&lt;span&gt;&amp;nbsp;occurred in groups exposed to&amp;nbsp;&lt;/span&gt;&lt;i&gt;A. plicata&lt;/i&gt;&lt;span&gt;&amp;nbsp;after 1 and 5 d of depuration but not in groups exposed after 15 and 30 d. The bacterium was not isolated from either the&amp;nbsp;&lt;/span&gt;&lt;i&gt;A. plicata&lt;/i&gt;&lt;span&gt;&amp;nbsp;or the Arctic char in the 15- and 30-d groups. Results indicate that the current minimum 30-d quarantine of freshwater bivalves destined for relocation to prevent spread of zebra mussels&amp;nbsp;&lt;/span&gt;&lt;i&gt;Dreissena polymorpha&lt;/i&gt;&lt;span&gt;&amp;nbsp;is sufficient to allow depuration of a fish pathogen and, thus, to prevent the spread of disease.&lt;/span&gt;&lt;/p&gt;</dc:description>
