Pathology and Microbiology
Spores identified as Myxobolus neurobius were found in head homogenates of both wild young Atlantic salmon Salmo salar and Arctic char Salvelinus alpinus . Formalin-preserved spores from Atlantic salmon measured an average of 12.9 x 9.4 mu m and contained two polar capsules that measured 6.4 x 2.9 mu m. The spores from the Arctic char appeared morphologically identical by bright-field microscopy to those from the Atlantic salmon except they measured 13.7 x 9.6 mu m and had polar capsules that Show moreSpores identified as Myxobolus neurobius were found in head homogenates of both wild young Atlantic salmon Salmo salar and Arctic char Salvelinus alpinus .
