Copyright policy )Elaphostrongylus spp. from Scandinavian cervidae - a scanning electron microscope study (SEM)
<p>Nematodes of the genus <em>Elaphostrongylus</em> collected from moose (<em>Alces alces</em> L.), reindeer (<em>Rangifer tarandus tarandus</em> L.), and red deer (<em>Cervus elaphus</em> L.), respectively, were studied by means of scanning electron microscopy. Morphological differences in the ribs of the genital bursa were demonstrated. The <em>Elaphostrongylus</em> species from reindeer and red deer differed from each other in four ribs of the genital bursa. These results agree with the morphological characters of <em>E. cervi</em> and <em>E. rangiferi</em> described by Cameron (1931) and Mitskevitch (1960). The genital bursa of <em>Elaphostrongylus</em> sp. from moose, in accordance with the description of <em>E. alces</em> by Steen <em>et al</em>. (1989) showed characteristics differing from those found in <em>Elaphostrongylus</em> spp. from reindeer and red deer respectively. These results support the hypothesis that there are three separate species of <em>Elaphostrongylus</em> present in Scandinavian Cervidae.

De hanliga bursorna med sin a stodjeribbor uppvisade variationer i utseende, langd och placering mellan dessa rundmaskar. De arter av <em>Elaphostrongylus </em>funna hos ren och kronhjort skilde sig åt avseende fyra stodjeribbor på de hanliga bursorna. Dessa resultat stammer val overens med de karaktarer som tidigare ar beskrivna av Cameron(1931) och av Mitskevich (1960). Den hanliga bursan hos arten<em> Elaphostrongylus</em> funnen hos alg, vilken tidigare ar beskriven av Steen <em>et al</em>. (1989), visade upp ett utseende som skilde sig från bursorna hos de <em>Elaphostrongylus</em>-arter funna hos ren och kronhjort. Dessa resultat stoder hypotesen om tre skilda arter av <em>Elaphostrongylus</em> hos skandinaviska hjortdjur.</p>
