Abstract
Comparison of the Helicobacter nemestrinae 16S ribosomal DNA with published homologous sequences from members of the genera Helicobacter, Wolinella, and Campylobacter reveals a close relationship between H. nemestrinae, H. pylori, and H. acinonyx. This finding is unexpected since these species differ significantly in their DNA guanine-plus-cytosine contents (24 to 38 mol%).
摘要
将猪幽门螺杆菌16S核糖体DNA与已发表的来自幽门螺杆菌属、沃氏菌属和弯曲菌属成员的同源序列进行比较，结果显示猪幽门螺杆菌、幽门螺杆菌和猎豹幽门螺杆菌之间存在密切关系。这一发现出乎意料，因为这些物种的DNA鸟嘌呤加胞嘧啶含量差异显著（24%至38摩尔%）。
