Resurrection and Redescription of Varestrongylus alces (Nematoda: Protostrongylidae), a Lungworm of the Eurasian Moose ( Alces alces ), with Report on Associated Pathology
Background: Varestrongylus alces, a lungworm in Eurasian moose from Europe has been considered a junior synonym of Varestrongylus capreoli, in European roe deer, due to a poorly detailed morphological description and the absence of a type-series. Methods: Specimens used in the redescription were col...
