We described an association between a strain of the nematode Caenorhabditis briggsae, i.e. KT0001, and the bacteria Serratia sp. SCBI (South African Caenorhabditis briggsae isolate), which was able to kill the insect Galleria. Here we show that the Serratia sp. SCBI lines the gut of the nematode, similar to the Heterorhabditis-Photorhabdus complex, indicating that the association is possibly internal. We also expand on the relevance of this tripartite, i.e. insect-nematode-bacteria, interaction in the broader evolutionary context and Caenorhabditis natural history.
我们描述了秀丽隐杆线虫的一种品系,即 KT0001,与细菌沙雷氏菌 SCBI(南非秀丽隐杆线虫分离株)之间的关联,这种细菌能够杀死昆虫家蚕。在这里,我们表明沙雷氏菌 SCBI 菌株排列在线虫的肠道中,类似于异小杆线虫-发光杆菌复合物,这表明这种关联可能是内部的。我们还在更广泛的进化背景和秀丽隐杆线虫自然史中扩展了这种三方,即昆虫-线虫-细菌相互作用的相关性。
