is a highly infectious bacterium responsible for melioidosis, a systemic disease prevalent in Northern Australia and Southeast Asia. Melioidosis is a community-acquired infectious disease caused by , which thrives in tropical regions. This study presents the complete genome sequences of 18 isolates from clinical and environmental settings in Kelantan, Malaysia. Clinical isolates were characterized based on patient outcomes: recovery 6), relapse 4), and death due to melioidosis 6), with two environmental isolates that were obtained from soil samples. Draft genome sequences of the isolates were generated using Illumina HiSeq sequencing technology. The 18 genomes have an average length of 7,823, 977 bp (7,587,408-8,243,305 bp), an average GC content of 67.4%, with a mean N50 length and contigs of 47,798 bp and 2,882, respectively. RAST identified an average of 9,671 CDS and 64 RNAs per genome. A total of 144 virulence genes were identified across the dataset, including ADA and G genes. Antimicrobial resistance gene detection revealed a predicted resistance profile involving the OXA-59 gene, conferring resistance to beta-lactam antibiotics, present in all 18 genomes. MLST profiles revealed ST54 as the most common sequence type, corresponding to isolates USM003, USM010, USM011, USM013, and USM014. The 18 draft genomes also showed a close phylogenetic relationship with other genomes from Southeast Asia. In summary, the complete genome sequences of 18 isolates have been elucidated and provide a valuable resource to investigate the genetic diversity and virulence profiles of .
是一种导致类鼻疽的高传染性细菌,类鼻疽是一种在澳大利亚北部和东南亚流行的全身性疾病。类鼻疽是一种由在热带地区大量繁殖的引起的社区获得性传染病。本研究展示了从马来西亚吉兰丹州的临床和环境样本中分离出的18株的完整基因组序列。临床分离株根据患者预后进行分类:康复(6例)、复发(4例)以及因类鼻疽死亡(6例),另外有两株环境分离株是从土壤样本中获得的。分离株的基因组草图序列是使用Illumina HiSeq测序技术生成的。这18个基因组的平均长度为7,823,977 bp(7,587,408 - 8,243,305 bp),平均GC含量为67.4%,平均N50长度和重叠群分别为47,798 bp和2,882。RAST鉴定出每个基因组平均有9,671个编码序列和64个RNA。在整个数据集中总共鉴定出144个毒力基因,包括ADA和G基因。抗菌抗性基因检测显示预测的抗性谱涉及OXA - 59基因,该基因赋予对β - 内酰胺抗生素的抗性,存在于所有18个基因组中。多位点序列分型谱显示ST54是最常见的序列类型,对应于分离株USM003、USM010、USM011、USM013和USM014。这18个基因组草图还显示与来自东南亚的其他基因组有密切的系统发育关系。总之,已阐明18株的完整基因组序列,为研究的遗传多样性和毒力谱提供了宝贵资源。
