Abstract
Comparison of partial 16S rRNA sequences from representative Campylobacter species indicates that the Campylobacter species form a previously undescribed basic eubacterial group, which is related to the other major groups only by very deep branching. This analysis was extended to include the spiral bacterium associated with human gastritis, Campylobacter pylori (formerly Campylobacter pyloridis). The distance between C. pylori and the other Campylobacter species is sufficient to exclude the pyloric organism from the Campylobacter genus. The results indicate that C. pylori is more closely related to Wolinella succinogenes than it is to the other Campylobacter species inspected. Another close relative of the campylobacters was found to be Thiovulum, a sulfide-dependent marine bacterium.
摘要
对代表性弯曲杆菌属物种的部分16S rRNA序列进行比较表明，弯曲杆菌属物种形成了一个以前未描述过的基本真细菌类群，该类群仅通过非常深的分支与其他主要类群相关。该分析扩展到包括与人类胃炎相关的螺旋菌幽门弯曲杆菌（以前称为幽门弯曲菌）。幽门弯曲杆菌与其他弯曲杆菌属物种之间的距离足以将幽门生物排除在弯曲杆菌属之外。结果表明，幽门弯曲杆菌与产琥珀酸沃林氏菌的关系比与所检测的其他弯曲杆菌属物种的关系更密切。弯曲杆菌的另一个近亲被发现是硫小杆菌，一种依赖硫化物的海洋细菌。
