Pathogenic role of gastric Helicobacter sp in domestic carnivores

As a result of phylogenic studies using new molecular biology techniques and fundamental experimental studies, we now know more about helicobacteria in domestic carnivores, their morphologic characteristics, their taxonomia and more important we know more about their ecological niche. Few clinical studies have been carried out, but the ones that have been undertaken are interesting in that they confirm the extensive prevalence of Helicobacter infections in domestic carnivores and underline their role in the genesis of the inflammatory gastropathies observed in these species. Finally, recent observations have demonstrated the ubiquitous character of these helicobacteria by showing their presence in the stomach of man, dog and cat. This ubiquitous character has led some scientists to consider the potential zoonotic risk of the human infection by Helicobacter heilmannii, felis or pylori.
