Burkholderia pseudomallei, the etiological cause of melioidosis, is a soil saprophyte endemic in South-East Asia, where it constitutes a public health concern of high-priority. Melioidosis cases are sporadically identified in nonendemic areas, usually associated with travelers or import of goods from endemic regions. Due to extensive intercontinental traveling and the anticipated climate change-associated alterations of the soil bacterial flora, there is an increasing concern for inadvertent establishment of novel endemic areas, which may expand the global burden of melioidosis. Rapid diagnosis, isolation and characterization of B. pseudomallei isolates is therefore of utmost importance particularly in non-endemic locations.
We report the genome sequences of two novel clinical isolates (MWH2021 and MST2022) of B. pseudomallei identified in distinct acute cases of melioidosis diagnosed in two individuals arriving to Israel from India and Thailand, respectively. The data includes preliminary genetic analysis of the genomes determining their phylogenetic classification in rapport to the genomes of 131 B. pseudomallei strains documented in the NCBI database. Inspection of the genomic data revealed the presence or absence of loci encoding for several documented virulence determinants involved in the molecular pathogenesis of melioidosis. Virulence analysis in murine models of acute or chronic melioidosis established that both strains belong to the highly virulent class of B. pseudomalleii.
导致类鼻疽病的病原菌是假鼻疽伯克霍尔德菌,它是东南亚地区的土壤腐生物,是高度优先关注的公共卫生问题。非流行地区偶尔会发现类鼻疽病例,通常与旅行者或从流行地区进口的货物有关。由于广泛的洲际旅行以及预期的气候变化相关的土壤细菌菌群的改变,人们越来越担心会无意中建立新的流行地区,这可能会增加类鼻疽病的全球负担。因此,快速诊断、分离和鉴定假鼻疽伯克霍尔德菌分离株非常重要,特别是在非流行地区。
我们报告了两株新型临床分离株(MWH2021 和 MST2022)的基因组序列,这两株假鼻疽伯克霍尔德菌分别从来自印度和泰国的两名个体的不同急性类鼻疽病病例中分离得到。这些数据包括对基因组进行初步遗传分析,以确定它们与 NCBI 数据库中记录的 131 株假鼻疽伯克霍尔德菌菌株的基因组在系统发育分类上的关系。对基因组数据的检查显示了存在或不存在编码几种已记录的毒力决定因素的基因,这些因素涉及类鼻疽病的分子发病机制。在急性或慢性类鼻疽病的小鼠模型中的毒力分析表明,这两种菌株都属于假鼻疽伯克霍尔德菌的高毒力类。
