Helicobacter-like organisms in the stomach of pigs with and without gastric ulceration

Methods: Stomachs of pigs from four farms with diverse management systems were examined. The presence of Helicobacter was determined using an in-situ urease mapping technique and performing microscopic examination using Warthin-Starry silver stain. Culture was attempted using methods appropriate for Campylobacter species and Helicobacter pylori. The presence of lesions in the pars oesophagea based on macroscopic examination was recorded.
