Pseudomonas Infections in Mink with Special Reference to Pseudomonas Vasculitis in Pulmonary Lesions

Abstract

Pulmonary lesions associated with Pseudomonas infections in mink were studied histologically. In peracute cases the injury consisted of hemorrhagic necrosis of the lung tissue. In later stages of progression the widespread hemorrhagic necrosis was followed by leuco-cytic infiltration and exudation of fibrin. These latter changes also included classic Pseudomonas vasculitis such as this vascular lesion is described in humans and some laboratory animals.
