Specific identification of microorganisms in the environment is important but challenging, especially at the species/strain level. Here, we have developed a novel k-mer-based approach to select strain/species-specific probes for microbial identification with diagnostic microarrays. Application of this approach to human microbiome genomes showed that multiple (≥10 probes per strain) strain-specific 50-mer oligonucleotide probes could be designed for 2,012 of 3,421 bacterial strains of the human microbiome, and species-specific probes could be designed for most of the other strains. The method can also be used to select strain/species-specific probes for sequenced genomes in any environments, such as soil and water.
环境中微生物的特异性鉴定很重要,但具有挑战性,尤其是在种/菌株水平。在这里,我们开发了一种新的基于 k- -mer 的方法,用于通过诊断微阵列选择微生物鉴定的菌株/种特异性探针。该方法在人类微生物组基因组中的应用表明,可针对人类微生物组的 3421 种细菌菌株中的 2012 种设计多个(每个菌株≥10 个探针)菌株特异性 50- 碱基寡核苷酸探针,并且可为大多数其他菌株设计种特异性探针。该方法还可用于为任何环境(如土壤和水)中的测序基因组选择菌株/种特异性探针。
