Abstract

Multilocus enzyme electrophoresis of 161 Hafnia alvei isolates from 158 hosts and 3 water column samples collected in Australia revealed that this species consists of two genetically distinct groups. The two groups of H. alvei differed significantly in their genetic structure and host distribution. The taxonomic class of the host but not geographic locality explained a significant proportion of the observed genetic and biochemical variation among strains within each genetic group.

摘要

对从澳大利亚采集的158个宿主和3个水柱样本中分离出的161株蜂房哈夫尼亚菌进行多位点酶电泳分析后发现，该物种由两个基因上截然不同的群体组成。这两组蜂房哈夫尼亚菌在遗传结构和宿主分布上存在显著差异。宿主的分类类别而非地理位置，解释了每个遗传群体内菌株间观察到的很大一部分遗传和生化变异。
