Severity of aortic aneurysms and C. gracilis in the gut in patients with TAK. A PCR electrophoretic analysis. The upper images show the amplified products of the universal 16S primers (first PCR), and the lower images show those of C. gracilis specific 16S primers (second PCR). B Aortic aneurysm-related event-free survival in the patients who were positive or negative for C. gracilis by PCR. C Mean of the maximum short diameters in four regions of the aorta. D Three-dimensional computed tomography (3D-CT) images before interventions and positivity of C. gracilis by PCR in each patient with TAK who had interventions owing to aortic dilatation. Case 16 is shown as a reference for patients with TAK without interventions. Images in Case 6 are chest CT and abdominal CT. Images of 3D-CT were missing in Cases 12 and 15
