A slow-growing aerobic bacterium, named Shr3, was isolated from an arid area in Tunisia, and was only distantly related to all other known organisms at <82% similarity of 16S rRNA gene sequences. Along with other genetic, biochemical and physiological properties, the isolate Shr3 was shown to be a highly novel new species, representing a new Class within the Phylum Proteobacteria. This taxonomic proposal has been subject to expert reviews.A copy (sub-culture) of the Shr3 strain has been deposited at National Collection of Industrial, Food and Marine Bacteria (NCIMB), UK. In addition to Shr3, two more isolates were also characterized to propose new taxa, i.e., species, genera, families, orders, or higher.

一种生长缓慢的需氧细菌，命名为Shr3，从突尼斯的干旱地区分离出来，与所有其他已知生物只有远亲关系，16S rRNA基因序列的相似性<82%。结合其他遗传、生化和生理特性，分离物Shr3被证明是一个高度新颖的新种，代表了变形菌门的一个新纲。这一分类学建议已经过专家审查。Shr3菌株的一个副本（传代培养）已存放在英国国家工业、食品和海洋细菌收集中心（NCIMB）。除Shr3外，还对另外两个分离物进行了鉴定，提出了新的分类群，即种、属、科、目或更高的分类群。
