Haematoxylin and eosin stain, bar = 500 μm b. Transverse section of four adult A. vasorum (arrows) in the pulmonary artery of the same stoat. Haematoxylin and eosin stain, bar = 500 μm. Inset: Transverse section of a nematode in the pulmonary artery of a weasel. Its location within the artery and the clearly visible lateral chords (arrows) are consistent with A. vasorum.
