| muscular sarcocystosis in two arctic foxes (vulpes lagopus) due to sarcocystis arctica n. sp.: sarcocyst morphology, molecular characteristics and phylogeny. | the arctic fox (vulpes lagopus) is a critically endangered species in norway, and therefore, the small population is closely monitored, and most foxes found dead are subjected to necropsy. in two deceased foxes, thin-walled muscular sarcocysts were first detected in histological sections, and numerous sarcocysts were later found in frozen and thawed muscle samples from fox 1. these sarcocysts measured 1-12 × 0.1-0.25 mm and had closely spaced, short, knob-like protrusions, giving the cysts a ser ... | 2014 | 24297693 |
