- Abstract
The aim of this study was to relate the anatomopathological findings of naturally occurring subclinical gastric lesions in piglets, with or without Helicobacter spp. through immunohistochemistry. Forty-eight piglets of commercial genetic lineage were used. The animals were acquired in a commercial farm, with an average weight of 34 kg and an average age of 79 days, and after slaughter, their stomachs were collected and evaluated. Samples from the glandular and aglandular anatomical regions were evaluated. Macroscopically, 34 (70.83%) samples had lesions on aglandular region, while 14 (29.17%) nothing had. Of the injured stomachs, 14 were classified as grade 1, six as grade 2 and 14 as grade 3. Microscopically, 44 samples (91.66%) showed parakeratosis. Of these, 22 showed a discreet manner, 20 moderate and two severe. In the glandular region, in 41 (85.4%) samples there was a change in at least one of the three regions, and only seven animals (14.6%) showed no change in any of the three. Fourteen samples showed increased muciparous activity, two showed erosion and five hyperemia. The lesions were higher in antral regions and cardic, followed the fundus. In relation to immunohistochemistry, 21(43.8%) samples were negative in all areas, 24 (50%) were positive in at least one, and none were positive in all. The anatomopathological findings showed a statistical relationship with the bacteria, and its immunostaining, not associated with gastric lesions in certain regions, demonstrates its saprophytic and opportunistic character.
