A 16-year-old Caucasian male presented with nausea, vomiting, and abdo
minal pain. Endoscopy revealed erythematous antral mucosa with four di
screte gastric ulcers. Biopsies showed multiple spiral organisms, 4-6
mu m in length, lying in the mucous layer on the surface. The organism
s were strongly Giemsa positive and weakly CLOtest positive. They did
not stain with Warthin-Starry silver or Gram-Weigert stains. Electron
microscopy revealed fragments of Gastrospirillum hominis, with its cha
racteristic spiral shape and length of 4 mu m in the plane of section.
We believe that this is one of the first reported pediatric cases in
North America.
