Crenosoma vulpis larva (fox lungworm) in a juvenile opossum from Northern Virginia, USA

Abstract

A juvenile opossum, seeking warmth in a stairwell in Northern Virginia, was pale, underweight and subsequently found to be infected with Crenosoma vulpis, a type of lungworm. To our knowledge, this parasitic infection has not previously been reported in the Virginia opossum (Didelphis virginiana). The opossum was treated and released.
