金黄色葡萄球菌是一种新出现的菌种,其引起的感染与金黄色葡萄球菌引起的感染相当。到目前为止,它涉及很少的慢性或持续性感染。在这项研究中,我们描述了一个持续的假体关节感染(PJI)影响一名年轻女子的情况。我们在体外研究了致病性S. argenteus菌株(骨细胞侵袭、生物膜形成和炎症诱导)进行基因组分析,并与另外两株S. argenteus和两个S.金黄色葡萄球菌分离株看来,这个S。Argenteus PJI菌株结合了生物膜形成、成骨细胞侵袭和细胞内持久能力以及可能参与逃避宿主免疫防御的基因,这可能解释了感染的慢性化。
Staphylococcus argenteus is an emerging species responsible for infections comparable to those induced by Staphylococcus aureus. It has been involved in few chronic or persistent infections so far. In this study, we described a case of a persistent prosthetic-joint infection (PJI) affecting a young woman. We investigated in vitro the virulence traits of the incriminated S. argenteus strain (bone cell invasion, biofilm formation and induction of inflammation) and analyzed its genome, in comparison with two other strains of S. argenteus and two S. aureus isolates. It appeared that this S. argenteus PJI strain combined biofilm formation, osteoblast invasion and intracellular persistence abilities together with genes potentially involved in the escape of the host immune defenses, which might explain the chronicization of the infection.
