Abstract

A polyphasic identification approach was used to investigate the taxonomic position of Campylobacter-like isolates recovered from barnacle geese (Branta leucopsis) and Canada geese (Branta candensis). Seven strains were selected from a collection of 21 isolates and analyzed by extensive phenotypic testing; four strains were characterized by 16S rRNA gene sequence analysis. The results clearly identified the bird isolates as Helicobacter canadensis, recently described as an emerging human pathogen. This is the first report of an animal reservoir for this organism and of its presence in Europe and confirms the zoonotic potential of H. canadensis.

摘要

采用多相鉴定方法研究了从白额黑雁(Branta leucopsis)和加拿大雁(Branta candensis)中分离出的类弯曲杆菌菌株的分类地位。从21株分离物中挑选出7株进行广泛的表型测试分析;4株通过16S rRNA基因序列分析进行特征鉴定。结果明确将鸟类分离物鉴定为加拿大幽门螺杆菌,该菌最近被描述为一种新出现的人类病原体。这是关于该生物体动物宿主及其在欧洲存在情况的首次报告,并证实了加拿大幽门螺杆菌的人畜共患病潜力。
