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.
