  <dc:description>In total, 288 slimy sculpins, &lt;i&gt;Cottus cognatus&lt;/i&gt;, were collected in September 2003 from 6 Lake Michigan, U.S.A., ports, along with 220 ninespine sticklebacks, &lt;i&gt;Pungitius pungitius&lt;/i&gt;, from 3 ports. The ports included Waukegan, Illinois; Port Washington (PW) and Sturgeon Bay (SB), Wisconsin; and Manistique (MS), Frankfort (FF), Ludington (LD), and Saugatuck, Michigan. &lt;i&gt;Echinorhynchus salmonis&lt;/i&gt; infected sculpins from 6 ports, &lt;i&gt;Acanthocephalus dirus&lt;/i&gt; infected sculpins from 4 ports, and &lt;i&gt;Neoechinorhynchus pungitius&lt;/i&gt; infected sculpins from 3 ports. &lt;i&gt;Echinorhynchus salmonis&lt;/i&gt; infected significantly more sculpins at PW and at FF than at MS and LD. There were several significant differences in the intensities and abundances of &lt;i&gt;E. salmonis&lt;/i&gt; among ports. &lt;i&gt;Acanthocephalus dirus&lt;/i&gt; significantly infected more sculpins and had significantly higher abundances at FF than at PW, MS, and LD. &lt;i&gt;Echinorhynchus salmonis&lt;/i&gt;, &lt;i&gt;A. dirus&lt;/i&gt;, and &lt;i&gt;N. pungitius&lt;/i&gt; infected sticklebacks from SB, MS, and FF. &lt;i&gt;Neoechinorhynchus pungitius&lt;/i&gt; significantly infected more sculpins and more sticklebacks, and it had significantly higher abundances at MS than at FF. &lt;i&gt;Neoechinorhynchus pungitius&lt;/i&gt; was the most common acanthocephalan in &lt;i&gt;C. cognatus&lt;/i&gt; and &lt;i&gt;P. pungitius&lt;/i&gt; at MS. These acanthocephalan species infecting &lt;i&gt;C. cognatus&lt;/i&gt; and &lt;i&gt;P. pungitius&lt;/i&gt; corresponded in their occurrence to those organisms that serve as their intermediate hosts found in the stomachs of both fish species. Potential changes in the diet of &lt;i&gt;C. cognatus&lt;/i&gt; played a role in significant differences found for &lt;i&gt;E. salmonis&lt;/i&gt; and &lt;i&gt;N. pungitius&lt;/i&gt; at MS. One of these acanthocephalan species was always the most numerous helminth species found in the digestive tracts of &lt;i&gt;P. pungitius&lt;/i&gt; and &lt;i&gt;C. cognatus&lt;/i&gt; from these Lake Michigan ports.</dc:description>
