BACKGROUND
Burkholderia thailandensis, a close relative of Burkholderia pseudomallei, has previously been reported only from Southeast Asia and North America. It is biochemically differentiated from B. pseudomallei by the ability to utilize arabinose. During the course of environmental sampling for B. pseudomallei in the Northern Territory of Australia, an isolate, MSMB 43, was recovered that is arabinose positive.
RESULTS
Genetic analysis using 16S rDNA sequencing and DNA/DNA hybridization indicates that MSMB 43 is most similar to B. thailandensis although multi-locus sequence typing indicates that this isolate is divergent from both B. pseudomallei and other described B. thailandensis.
CONCLUSION
We report the isolation and initial characterization of strain MSMB 43, which is a B. thailandensis-like isolate recovered in Australia.
背景
泰国伯克霍尔德菌是类鼻疽伯克霍尔德菌的近亲，此前仅在东南亚和北美有报道。它可利用阿拉伯糖，在生化特性上与类鼻疽伯克霍尔德菌有所不同。在澳大利亚北领地对类鼻疽伯克霍尔德菌进行环境采样的过程中，分离出一株阿拉伯糖阳性菌株MSMB 43。
结果
使用16S rDNA测序和DNA/DNA杂交进行的基因分析表明，MSMB 43与泰国伯克霍尔德菌最为相似，尽管多位点序列分型表明该分离株与类鼻疽伯克霍尔德菌和其他已描述的泰国伯克霍尔德菌不同。
结论
我们报告了菌株MSMB 43的分离及初步特征，它是在澳大利亚分离出的一株类似泰国伯克霍尔德菌的菌株。
