Abstract：
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.
The aim of this study was to investigate the presence of some zoonotic species of genus Helicobacter in companion dogs.
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).
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.

摘要：
像狗这样的伴侣动物在许多人的生活中起着重要的作用，通常被认为是家庭成员，但肯定的是,与它们的任何接触都会带来传播人畜共患病原体的固有风险。这些病原体之一是螺杆菌属,其与人和动物中的许多疾病有关。
这项研究的目的是调查伴侣犬中某些人畜共患的螺杆菌属物种的存在。
通过在特殊培养基中培养，9个样本(9%)被检测为感染(2个纯培养物和7个混合培养物)。基于多重PCR，13个样本（13％）被幽门螺杆菌感染。尽管他们都没有感染幽门螺杆菌。物种特异性PCR显示38.5%或5/13的样本感染了H.heilmannii,而15.45%或2/13的样本被H.billis感染。多因素logistic回归分析显示年龄因素对幽门螺杆菌有显著影响。感染（比值比[OR]=2.42，p=0.01）。
这项研究揭示了幽门螺杆菌的粪便传播可以忽略不计。此外，由于在粪便中检测到H.Heilmannii和H.billis，以及它们与人类胃病的关系，狗主人应该接受关于狗的人畜共患细菌感染的风险和传播方式的教育。
