Microscopic findings in ileocolonic biopsy specimens (second colonoscopy) in a man in Japan who had recurrent Helicobacter fennelliae bacteremia. A) Morphologic features of the bacteria in a cecal tissue suspension with Gram staining (original magnification ×2,000). Arrow indicates gram-negative spiral bacilli. B) Histologic findings in a biopsy specimen taken from the transverse colon with hematoxylin-eosin staining (original magnification ×200). The colonic mucosa shows mild leukocytic infiltration. C) Histologic findings in a biopsy specimen taken from the transverse colon with Warthin-Starry silver staining (original magnification ×200). Bacteria are aggregated in crypts (arrowheads) D) Morphologic features of bacteria obtained from the transverse colon with Warthin-Starry silver staining (original magnification ×1,000). A cluster of spiral bacilli was observed.
