Abstract
Among diseases of the gastrointestinal tract of pigs, gastric ulcerative gastritis are the most common. It is generally believed that pigs get sick with peptic ulcer disease and gastritis from poor feeding, housing, and various diseases. The pathogenesis development of ulcer and gastritis in pigs has a multifactorial origin and mostly remains unclear. The assessment of the pathomorphological state of the stomach of pigs admitted for slaughter clinically healthy showed that in 57 % of cases had severe hyperkeratosis, covering more than 50 % of the surface of the stomach, erosions and / or ulcers. The DNA of H. suis bacteria was detected by molecular genetic method in 70 % of the gastric mucosa samples examined. Analysis of pathomorphological changes in the stomach depending on the detection of H. suis in it, showed that changes in case of gastritis with helicobacteriosis were more pronounced. Microscopy revealed structural changes in the gastric mucosa with varying degrees of intensity of fibrosis, atrophy of glandular structures and cell infiltration. The relation between the presence of H. suis in the fundal or pyloric parts of the stomach and the severity of lesions in the stomach of pigs was found and shown.
