We report the isolation of a novel helicobacter isolated from the caecum of the Siberian hamster (Phodopus sungorus). Sequence analysis showed 97% sequence similarity to Helicobacter ganmani. In addition, we report the co-infection of these Siberian hamsters with a Campylobacter sp. and a second Helicobacter sp. with 99% sequence similarity to Helicobacter sp. flexispira taxon 8 (Helicobacter bilis), a species isolated previously from patients with bacteraemia. Gross necropsy and histopathology did not reveal any overt pathological lesions of the liver and gastrointestinal tract that could be attributed to the Helicobacter or Campylobacter spp. infections. This is the first helicobacter to be identified in the Siberian hamster and the first report of co-infection of Helicobacter spp. and Campylobacter sp. in asymptomatic Siberian hamsters.
我们报告了从西伯利亚仓鼠（Phodopus sungorus）盲肠中分离出一种新型幽门螺杆菌。序列分析显示，其与甘氏幽门螺杆菌有97%的序列相似性。此外，我们报告了这些西伯利亚仓鼠同时感染了一种弯曲杆菌属细菌和另一种幽门螺杆菌，后者与弯曲螺旋形幽门螺杆菌分类群8（胆汁幽门螺杆菌）有99%的序列相似性，该菌种先前从菌血症患者中分离得到。大体尸检和组织病理学检查未发现任何可归因于幽门螺杆菌或弯曲杆菌属细菌感染的肝脏和胃肠道明显病理病变。这是在西伯利亚仓鼠中鉴定出的首例幽门螺杆菌，也是无症状西伯利亚仓鼠中幽门螺杆菌属细菌和弯曲杆菌属细菌共同感染的首次报道。
