This study describes the bacterial community composition within the intestinal ecosystem of rainbow trout (Oncorhynchus mykiss) using high-throughput 16S rRNA gene sequence analysis. Sequences from intestinal samples from Chinook salmon (Oncorhynchus tshawytscha) farmed in New Zealand and rainbow trout farmed in Turkey were also included for comparative purposes. The results revealed that the most abundant operational taxonomic units (OTUs) were affiliated to the genus Mycoplasma, but were not specifically associated with any known species. Comparative analysis of 16S rRNA gene sequences indicated that these OTUs represent potentially novel species within the genus Mycoplasma.
本研究采用高通量 16S rRNA 基因序列分析的方法，描述了虹鳟鱼肠道生态系统中的细菌群落组成。本研究还包括了新西兰养殖的奇努克鲑（Oncorhynchus tshawytscha）和土耳其养殖的虹鳟肠道样本的序列，以供比较。结果表明，最丰富的操作分类单元（OTUs）与支原体属（Mycoplasma）有关，但与任何已知物种均无特定关联。16S rRNA 基因序列的比较分析表明，这些 OTUs 代表支原体属中潜在的新型物种。
