Helicobacter pylori and Non-Helicobacter pylori Helicobacter (NHPH) Zoonotic Infections: A Survey Among Greek Veterinarians Aiming to Enhance Communication

Helicobacter species affect humans and animals, mainly causing gastrointestinal but also extra-gastrointestinal pathologies. Besides Helicobacter pylori, which is the main human pathogen, Non-Helicobacter pylori Helicobacters (NHPH) are also associated with human diseases, thus raising concern about their zoonotic potential. Veterinarians are considered a risk group for NHPH infections and act as first-line communicators to animal owners about their prophylaxis. Therefore, we aimed to assess the knowledge and perception of veterinarians working in Greece about Helicobacter pylori and NHPH by asking them to participate anonymously in an online 34-question survey. The questionnaire consisted of three sections regarding environmental exposure to Helicobacter spp.; know-how about clinical signs in various species, including personal human experience; and willingness to get updated information about NHPH. Of the 111 respondents, 41.4% had not heard of H. suis (NHPH), and 35.0% were unaware of the species that could be affected. Almost 60.0% of companion animal veterinarians rarely suspect and 20.0% never suspect Helicobacter spp. infections in the case of gastritis. Nevertheless, 41.0% of respondents considered Helicobacter as zoonotic, and 87.0% wanted to receive information via professional channels and brochures. Despite the limited number of respondents and the exploratory nature of our study, as with similar data from Portugal, we emphasize the need to train veterinarians to have a more targeted focus on the zoonotic potential of Helicobacter within a One Health approach.
