Parietal cells from an uninfected control animal (left) and from a lamb euthanased on Day 10 p.i. after infection with 35,000 L3 Teladorsagia circumcincta (centre and right).
Left: TEM showing a central nucleus (N), cytoplasm filled with mitochondria and visible intracellular canaliculi; centre: LM section showing parietal cells stained brown with anti-H+/K+-ATPase antibody and a vacuolated parietal cell (arrow); right: TEM of parietal cells containing one or more vacuole-like structures (V), pale cytoplasm, reduced numbers of mitochondria and swollen pale nuclei. Bar = 5 μm (left, right). 50 μm (centre).
