Background Helicobacter pylori is one of the most common bacterial infections and is widespread globally. It causes a variety of gastrointestinal disorders, though a great proportion of infections are asymptomatic. A total of 143 fresh stool samples were collected from apparently healthy farm and pet animals (43 cattle, 50 buffaloes, 50 sheep, 50 dogs, and 50 cats), in addition to 768 human stool samples. The samples were examined using stool antigen and rapid antibody tests, and further confirmation of glmM “human antigen-positive samples and animal milk samples” was conducted by polymerase chain reaction (PCR). Results The prevalence rates of H. pylori infection in animals were 22.2% and 16% in antibody and stool antigen tests, respectively. The detection rates were 28%, 24%, 12%, 10%, and 4.7% in cats, dogs, buffaloes, sheep, and cattle, respectively. On the other hand, the prevalence rate of H. pylori infection in human stool samples was 74.8%, and a statistically significant association was observed between prevalence and several factors, such as sex, age, and locality. PCR was performed to detect the glmM gene of H. pylori, and this gene was found in 21 of 27 human antigen-positive samples and 5 of 13 animal milk samples. Conclusions H. pylori was detected in both human and animal samples. Furthermore, glmM was found in milk and human samples. Our findings suggest that pet and farm animals could transmit H. pylori infection to humans.

“…Sharing plates, glasses, and other utensils with an individual infected with H. pylori can potentially lead to transmission. The bacteria can survive on these surfaces and be transferred to another individual if proper cleaning and disinfection are not followed (Mezmale et al, 2020;She et al, 2023) (Table 1) (Dore et al, 1999;Stevenson et al, 2000;Dore et al, 2001;Fujimura et al, 2002;Turutoglu and Mudul, 2002;Quaglia et al, 2008;Meng et al, 2008;Angelidis et al, 2011;Safaei et al, 2011;Rahimi and Kheirabadi, 2012;Momtaz et al, 2014;Mousavi et al, 2014;Atapoor et al, 2014;Yahaghi et al, 2014;Esmaeiligoudarzi et al, 2015;Talaei et al, 2015;Bianchini et al, 2015;Osman et al, 2015;Abdel-Latif et al, 2016;Saeidi and Sheikhshahrokh, 2016;Hemmatinezhad et al, 2016;Ghorbani et al, 2016;Eldairouty et al, 2016;Gilani et al, 2017;Al-Mashhadany and Mayass, 2017;Khaji et al, 2017;Talimkhani and Mashak, 2017;Ranjbar et al, 2018;Hamada et al, 2018;Elhariri et al, 2018;Guessoum et al, 2018;Mashak et al, 2020;Kareem and Maaly, 2021;Elrais et al, 2022;Al-Shrief and Thabet, 2022;Asadi et al, 2023;…”

Helicobacteriosis is a common bacterial infection caused by Helicobacter pylori. It affects the stomach and small intestines, leading to inflammation. Bacteria can spread through contaminated food or water. This review explores the role of food in the transmission of H. pylori, drawing on research from the past three decades. People commonly acquire the infection during childhood, often from close family members. Crowded living conditions can also contribute to the spread. This review also discusses various risk factors and highlights the challenges of detecting H. pylori, particularly in its dormant form. Techniques like ribotyping and restriction fragment length polymorphism hold promise for tracing transmission routes, but more long-term studies are needed to account for potential confounding factors.
