The aim of the study was to estimate the occurrence, density, and characteristics of inflammatory infiltrations in swine with Helicobacter sp., and particularly Candidatus Helicobacter suis (CHS) infections. Gastric samples from 29 pigs were obtained from slaughterhouses. Helicobacer genus-specific and CHS-specific primers sets were used to determine the Helicobacter status in all animals, and density and characteristics of inflammatory infiltration were estimated during microscope examinations. Helicobacter infections were observed in all the examined cases, and gastritis was noted in most cases. Mononuclear cells (lymphocytes and plasma cells) mostly dominated in the inflammatory infiltrations, and neutrophils were observed more seldom. It was noted that pigs which had Helicobacter infections in this part of the gastric mucosa, also had more intensive inflammatory infiltrations than animals without infection. No differences in the density of inflammatory infiltrations in the body and pyloric antrum of the stomach were noted.

The aim of the study was to evaluate the frequency of the presence of antibodies to Helicobacter pylori and Helicobacter felis antigens in dogs. One hundred thirty two dogs of different age and sex were included in the study and divided in two groups. Serum samples and gastric biopsy specimens were taken during gastrointestinal endoscopy. The examined group consisted of 102 dogs with dyspeptic symptoms and pathological changes in gastric mucosa. The control group contained 30 clinically healthy animals. In the examined group Helicobacter spp. infection was established by direct microscopy and urease test. It was detected in 89.2% of the dogs, whereas in the control group, in 96.7% animals. In the culture of gastric biopsy specimens Helicobacter felis was the most frequently isolated strain. The anti-H. pylori IgG antibodies were detected in 24.5% serum samples of the examined dogs. The anti-H. felis IgG antibodies were identified in 30.4% samples of animals with gastritis and in 20% of healthy animals respectively. Antibodies of H. pylori antigens were not evaluated in healthy dogs. The antibodies to H. pylori and H. felis antigens were detected more frequently in dogs with gastritis than in healthy dogs.
