昆虫病原线虫4新种所携带共生菌的分子鉴定

 以16S rDNA为分子标记对中山大学有害生物控制及资源利用国家重点实验室近年从我国采集到并描述发表的斯氏属昆虫病原线虫4个新种所携带的共生菌进行分类鉴定，结果显示Steinernema akhursti所携带的共生菌很可能是Xenorhabdus属的一个新种，S aciari和S. leizhouense所携带的共生菌可能是Xenorhabdus属的两个近缘的新种或同一种的两个远缘菌株，而S. beddingi所携带的共生菌可能是Xenorhabdus bovienii的一个新菌株。

Molecular Identification of the Symbiotic Bacteria of Four Recently Described Species of Entomopathogenic Nematode

The taxonomic status of the symbiotic bacteria of four recently described species of entomopathogenic nematode was determined preliminarily using 16S rDNA as molecular marker. The results indicated that the symbiotic bacterium of Steinernema akhursti is likely to be a new species of Xenorhabdus, and those of Saciari and Sleizhouense perhaps are two new relative species or two distant strains of a new species of Xenorhabdus, while that of S. beddingii is a new strain of Xbovienii.
