“…A number of species of bacteria were found with Helicobacter heilmannii being the most common, but H. salomonis, H. bizzozeronii, and H. pylori were also detected. The study suggests that Helicobacter is relatively common in dogs with gastritis, and their saliva may be a source of infection for humans and other animals [14]. Abdel-Raouf et al came to similar conclusions, finding H. pylori in saliva in 45.3% of domestic dogs and 44.4% of domestic cats.…”

Helicobacter pylori is known as one of the most common Gram-negative bacteria in the world. Infection takes place via oral-oral, gastro-oral, and faecal-oral routes. The oral-oral route is considered to be the most common route of transmission. The presence of H. pylori in the saliva is considered as a factor inducing periodontal disease and tooth decay, as well as changes such as aphthous ulcers, leucoplakia, and lichen planus. Furthermore, existing bacteria in dental plaques such as Streptococcus mutans and Prevotela intermedia may produce bacteriocins that promote the growth of H. pylori. Recent studies have focused on infection of H. pylori mainly in adults, although infection often occurs in early childhood. As such, more studies concerning the developmental population are needed. Saliva, as an easily available biological material, may soon become an important source in the diagnosis of H. pylori infections, especially in children and adolescents.

“…Estudos apontam a presença de Helicobacter spp. na saliva de cães com gastrite, o que indica que a saliva é uma potencial fonte da bactéria (23,24). Apesar de não totalmente elucidado, suspeita-se que a infecção entre outros animais e seres humanos ocorra por via oral como, por exemplo, por meio de lambedura (24,25) .…”

ResumoBactérias do gênero Helicobacter spp. têm sido identificadas na mucosa gástrica de diferentes espécies de mamíferos, inclusive em caninos. Pacientes infectados têm gastrite histológica; no entanto, não são todos os portadores que apresentam sinais clínicos. O objetivo deste trabalho foi identificar as bactérias sugestivas de Helicobacter spp. pela impregnação pela prata e caracterizar as lesões histopatológicas observadas. Foram analisadas amostras de mucosas gástrica e entérica de 26 caninos. Para avaliação histopatológica, foi realizada avaliação qualitativa, na qual foram atribuídos escores de ausente (-) a acentuada (+++), considerando a densidade de bactérias espiraladas por campo (400x), presença de células inflamatórias e aglomerados linfoides. Dos 26 animais avaliados, 34,6% apresentaram positividade para helicobacteriose. A gastrite foi observada em 15,38% dos animais e a maior ocorrência de bactérias do gênero Helicobacter spp. foi observada em região de corpo/fundo gástrico (23%). Em nove amostras, seis de corpo/fundo gástrico e três de antro pilórico, foram observados aglomerados linfóides associados a Helicobacter spp. Por meio de Teste de Fisher, verificou-se associação positiva entre a presença de Helicobacter spp. e agregados linfoides (p<0,001). A infecção por Helicobacter spp. está associada com a presença de aglomerados linfóides em caninos. Palavras-chave: bactéria espiralada; cães; estômago; histoquímica; intestino.

Background: Companion animals like dogs play an important role in the lives of many people and are often considered to be members of families, but definitely, any contact with them poses an inherent risk of transmitting zoonotic pathogens. One of these pathogens is the genus Helicobacter which is linked to many disorders in human and animal. Objectives:The aim of this study was to investigate the presence of some zoonotic species of genus Helicobacter in companion dogs.Results: Through culturing in a special medium, nine samples (9%) were detected as infected (two pure and seven mixed culture). Based on multiplex-PCR, 13 samples (13%) were infected by Helicobacter spp. although none of them were infected by H. pylori. Species-specific PCR indicated that 38.5% or 5/13 of the samples were infected with H. heilmannii, while 15.45% or 2/13 of the samples were infected by H. billis. Multivariate logistic regression analysis showed that the age factor had a significant effect on Helicobacter spp. infection (odds ratio [OR] = 2.42, p = 0.01). Conclusion:This study revealed the negligible faecal transmission of H. pylori. Moreover, due to the detection of H. Heilmannii and H. billis in feces and their association with human gastric diseases, dog owners should be educated about the risks and transmission modes of zoonotic bacterial infections of dogs.
