“…In humans, the incidence of Helicobacter pylori in the oral cavity ranges from 0% to 100% (Majmudar et al 1990, Bernander et al 1993, Agüloǧlu et al 2006, Cellini et al 2010. Such a discrepancy may be caused by various factors.…”

The aim of this study was to identify the species and determine the prevalence of gastric Helicobacter in the saliva of dogs with gastritis. The study was carried out on 30 dogs of different breeds, genders and ages, which were diagnosed with gastritis. The nested-PCR method was used to detect Helicobacter spp. in saliva. Helicobacter bacteria were found in the saliva samples of 23 (76.6%) dogs. Helicobacter heilmannii was the most commonly detected species of gastric Helicobacter spp. in canine saliva, and was found in 22 (73.3%) cases. The results indicate that gastric Helicobacter spp. occurs relatively frequently in dogs with gastritis. Moreover, the saliva of dogs with gastritis may be a source of Helicobacter spp. infection for humans and other animals. However, further studies are needed to confirm this finding as the PCR method does not distinguish active from inactive infections.

“…Reports of unsuccessful attempts to culture H. pylori from the mouth [27,28] may be due to the organism being present in a non-culturable coccoid form, or as a transient member of the oral micro¯ora. However, detection by PCR indicates that the presence of H. pylori can be demonstrated in the mouths of a signi®cant number of infected individuals [7,8].…”

“…The diagnosis of RAS was based on accepted clinical criteria (16). The diagnosis of HSV infection was determined by serum examination (17 Discussion Culture is the gold standard for diagnosis of H. pylori infection (2,23), but it is very unlikely that oral H. pylori would be detected by culture (4,6,9). A low number of organisms or loss of viability during processing of dental specimens might contribute the poor sensitivity of culture (24,25).…”

“…Today, it is considered to be a pathogen important to the development of gastrointestinal ulcers and it has been implicated as a carcinogen for gastric cancer and mucosa-associated lymphoid-tissue lymphoma of the stomach (2,3). H. pylori has been detected in dental plaque, saliva, and the subgingival region (4)(5)(6)(7)(8), and there have been reports that H. pylori strains in the mouth and stomach are identical (7,9,10). It has been suggested that the oral cavity might be an alternative reservoir for H. pylori (11,12).…”

Abstract:Helicobacter pylori is an important pathogen involved in the development of gastrointestinal ulcers, but its involvement in oral ulcerous lesions is unclear. As culture is generally recognized as the gold standard for diagnosis of H. pylori infection, we employed this approach to assess the association of H.pylori with oral mucosal ulcerations. Samples were collected from patients with oral mucosal ulcerative disorders: 12 cases of recurrent aphthous stomatitis (RAS), 7 cases of herpes simplex virus (HSV) stomatitis, and 3 cases of erosive lichen planus (LP). Serum IgG antibodies against H. pylori were examined in all cases. All of the RAS and erosive LP cases were culturenegative for H. pylori, while two cases of HSV stomatitis were positive. The two culture-positive cases were also seropositve for the H. pylori antigen. It is suggested that H. pylori might not have a direct association with oral ulcerations. However, H. pylori in the oral cavity might exist in a non-culturable coccoid state without productive infection, and might form colonies only under special conditions such as HSV infection. (J. Oral Sci. 42, 225-229 , 2000)
