Coronary artery pathology seen in H. pylori-infected and uninfected macaques.
Panels A, B, C, and D show arteries from cagA positive (cagA+) animals. Panels A and C show severe necrosis. Panel B shows an atypical bulging plaque. Panels D, E, and F depict arteries that are near the median intimal thickness values for cagA-positive, cagA-negative (cagA-), and uninfected (Hp-) animals, respectively. Measurement lines shown in some images indicate the maximal intimal thickness for those sections.
