Abstract

<p>A method for estimating the density of Elaphostrongylus rangiferi larvae in reindeer faeces that have been deep frozen is described. The method involves the use of an inverted microscope with plankton counting chambers. Statistical data on the efficiency and sensitivity of the method are given. With fresh faeces, the results obtained with the method were not significantly different from those obtained with the Baermann technique. With faeces that had been stored in deep freeze, the method detected on average 30 per cent more larvae than the Baermann technique.</p><p>Metoder for &aring; estimere tettheten av hjernemarklarver i avf&oslash;ring fra reinsdyr.</p><p>Abstract in Norwegian / Sammendrag: En metode for &aring; estimere tettheten av hjernemarklarver i avf&oslash;ring som har v&aelig;rt dypfryst blir beskrevet.

Ved unders&oslash;kelse av fersk avf&oslash;ring skilte ikke de resultatene metoden ga seg fra de som ble oppn&aring;dd med Baermanns metode. Ved unders&oslash;kelse av avf&oslash;ring som hadde v&aelig;rt lagret dypfrosset ga metoden i gjennomsnitt 30 prosent flere larver enn Baermanns metode.</p>
