金黄色葡萄球菌是金黄色葡萄球菌细分的一种新种。目前尚不清楚该物种是否会引起食物中毒。本研究旨在研究两株怀疑为beS的食物中毒分离株的产肠毒素活性。阿根廷（Tokyo13064和Tokyo13069）。通过全基因组测序构建的系统发育树结果表明，这两个分离株与s型菌株更相似。阿根廷（MSHR1132）比任何一个。aureusstrain。此外，s。这两株菌株中均存在arggenteus，即两株菌株都属于CC75谱系，并且都缺乏acrtopqmoperon。因此，两者都被确定为S。argenteus。”两株菌株的辅助成分组成与MSHR1132不同。例如，在Tokyo13064和Tokyo13069中检测到这些与seb相关的金黄色葡萄球菌致病性岛SaPIishikawa11，但在MSHR1132中未检测到。结果表明，这两个分离株均属于不同的世系，均从MSHR1132世系中分离出来。Tokyo13064和Tokyo13069表达了高水平的S(arg) eband产生的S(arg)EB蛋白，表明两者都具有引起食物中毒的能力。我们的研究结果表明是这样的。含有特殊辅助成分的银可引起葡萄球菌疾病，如食物中毒，类似于toS。葡萄球菌。
Staphylococcus argenteusis a novel species subdivided from Staphylococcus aureus. Whether this species can cause food poisoning outbreaks is unknown. This study aimed to investigate the enterotoxigenic activities of two food poisoning isolates suspected to beS. argenteus(Tokyo13064 and Tokyo13069). The results for phylogenic trees, constructed via whole genome sequencing, demonstrated that both isolates were more similar to a type strain ofS. argenteus(MSHR1132) than anyS. aureusstrain. Moreover, the representative characteristics ofS. argenteuswere present in both strains, namely both isolates belong to the CC75 lineage and both lack acrtOPQMNoperon. Thus, both were determined to be “S. argenteus.” The compositions of the two isolates' accessory elements differed from those of MSHR1132. For example, theseb-related Staphylococcus aureus pathogenicity island, SaPIishikawa11, was detected in Tokyo13064 and Tokyo13069 but not in MSHR1132. Both isolates were suggested to belong to distinct lineages that branched off from MSHR1132 lineages in terms of accessory elements. Tokyo13064 and Tokyo13069 expressed high levels ofs(arg)eband produced S(arg)EB protein, indicating that both have the ability to cause food poisoning. Our findings suggest thatS. argenteusharboring particular accessory elements can cause staphylococcal diseases such as food poisoning, similarly toS. aureus.
