“…in dogs, gastric Helicobacter was determined at rates ranging from 67 to 100%. For this reason, studies have focused on dogs with the suspicion that dogs with whom people share their habitats may be the source [3,8,18,19]. In this study, H. pylori was determined in 54.28%, H. heilmannii in 82.85%, and H. felis in 8.57% by Real-time PCR in dogs, revealing the importance of studies on the prevalence and diagnosis of Helicobacter-like organisms in dogs.…”

“…Diagnosis of Helicobacter species is made with tests like rapid urease test, histopathology, culture, Polymerase Chain Reaction (PCR) from tissue samples or non-invasive tests such as urea breath test, blood tests, and serological tests [3,13,15,26]. The aim of this current study was to reveal the presence of H. felis, H. heilmannii, and H. pylori in the stomach and liver tissues taken during necropsy from owned, stray dogs and dogs kept in shelters, which died from different causes in the first stage, by Real-time PCR and histopathological examination.…”

Helicobacter species such as H. heilmannii, H. pylori, H. felis, H. bizzozeronii and H. salomonis have been identified in cats and dogs, and research suggesting that these species may be zoonotic agents and has been studied intensified in recent years. The aim of this study was to reveal the presence, comparing the histopathological findings and Real-time PCR results of H. felis, H. heilmannii, and H. pylori in the stomach and liver tissues taken during the necropsies of owned, stray or shelter dogs. The material of the study consisted of stomach and liver tissues taken from 35 dogs that died for different reasons and were brought for necropsy. DNA copies of H. heilmannii were detected by Real-time PCR in the liver samples of 30 dogs using H. heilmannii-specific primers. In the case of gastric samples, Real-time PCR detected H. heilmannii in 13 cases, H. pylori in 3 cases, both H. heilmannii and H. pylori in 13 cases, and H. felis, H. heilmannii and H. pylori in 3 cases. Microscopically, neutrophil leukocyte infiltration, epithelial degeneration, fibrosis and oedema in the lamina propia, and lymphoplasmacytic cell infiltration were determined in the stomachs. In the Hemotoxylin Eosin staining of the sections, 5 cases and 14 cases in the Warthin–Starry staining were found positive for Helicobacter-like microorganisms. Microscopically, dissociation of the remark cords and hydropic degeneration in hepatocytes, and focal mononuclear cell infiltrations in some sections were determined in the livers. In conclusion, with this study, it was understood that Real-time PCR analyzes are very useful in the diagnosis of H. felis, H. heilmannii, and H. pylori. However, histopathological examinations are necessary to associate the presence of bacteria with the development of the disease.

“…In this study, Helicobacter species were frequently found in both rivers, making these pathogens among the most threatening zoonotic pathogens under the concept of One Health [ 22 ]. Helicobacter species are present in most animals, such as dogs, cats, poultry, and even birds [ 2 ]. In fact, one study tested 80% of poultry positive for Helicobacter species [ 23 ], suggesting a high prevalence of this group of pathogens in different environments, including groundwater [ 24 ], soil [ 25 ], and common freshwater [ 26 ].…”

“…In the same country, drug-resistant H. pylori infections have also been identified [ 11 ]. Based on the zoonotic tendency of H. pylori , the high similarity of Helicobacter species in canines and human owners in Taiwan suggests cross-transmission between canines and humans [ 2 ]. Meanwhile, the high prevalence of H. pylori infection in southern Uganda may be due to a lack of clean water, poor sanitation, and overcrowding of the population [ 12 ].…”
