The authors have collected fecal and gastric samples from 110 pigs originating from 27 farms and a further 116 fecal samples from six additional farms. Fifty-eight pigs were selected randomly, whereas 52 pigs were chosen on the basis of the presence of gross lesions (catarrh, parakeratosis, ulcer). Samples for histological examination were collected from the oesophageal, cardiac, fundic and pyloric regions. The paraffin-embedded samples were sectioned and stained with hemalaun-eosin and subsequently examined for the presence of inflammation, parakeratosis or ulceration. Some sections were also stained with the Warthin-Starry method and there were structures similar to Helicobacter suis found on the mucosal surface and in the foveolae (Figure 3. and 4.). Of the 110 stomachs examined, 67 had gross lesions. Of the 82 stomach samples examined histologically, all sections showed some form of mucosal lesion [inflammation (Figure 1.), parakeratosis, ulcer (Figure 2.)]. The HpSA-ELISA-test, capable of detecting the somatic antigen of H. pylori even from disintegrated bacteria, was positive in all cases tested (Table 1.). This is likely to be due to the presence of bacteria that are antigenically related to H. pylori, or other, as yet unidentified Helicobacter species. Further histological studies are necessary to clarify the pathological significance of Helicobacter infection in swine.
