Abstract

Group A streptococcal (GAS; aka Streptococcus pyogenes) meningitis is a fulminant disease associated with high morbidity and mortality. To elucidate the mechanisms underlying the invasiveness of GAS in meningitis, we compared GAS isolates derived from five cases of meningitis to otitis and colonizing isolates. We did not observe differences in adherence to and invasion of human brain microvascular endothelial cells, virulence factors activity, or barrier disruption. Whole genome sequencing did not reveal particular invasiveness traits. Most patients previously suffered from otitis media suggesting that meningitis likely resulted from a continuous spread of the infection rather than being attributable to changes in the pathogen's virulence.

导致脑膜炎但无明显侵袭表型的 A 群链球菌菌株

A 组链球菌（GAS）脑膜炎导致很高的发病率和死亡率。为了阐明 GAS 在脑膜炎中的侵袭性，我们将 5 株 GAS 脑膜炎分离株与耳炎和定植分离株进行了比较。所有菌株的基因和毒力特征都相当，这表明脑膜炎很可能是由感染的持续传播引起的。

期刊介绍： MicrobiologyOpen is a peer reviewed, fully open access, broad-scope, and interdisciplinary journal delivering rapid decisions and fast publication of microbial science, a field which is undergoing a profound and exciting evolution in this post-genomic era. The journal aims to serve the research community by providing a vehicle for authors wishing to publish quality research in both fundamental and applied microbiology. Our goal is to publish articles that stimulate discussion and debate, as well as add to our knowledge base and further the understanding of microbial interactions and microbial processes. MicrobiologyOpen gives prompt and equal consideration to articles reporting theoretical, experimental, applied, and descriptive work in all aspects of bacteriology, virology, mycology and protistology, including, but not limited to: - agriculture - antimicrobial resistance - astrobiology - biochemistry - biotechnology - cell and molecular biology - clinical microbiology - computational, systems, and synthetic microbiology - environmental science - evolutionary biology, ecology, and systematics - food science and technology - genetics and genomics - geobiology and earth science - host-microbe interactions - infectious diseases - natural products discovery - pharmaceutical and medicinal chemistry - physiology - plant pathology - veterinary microbiology We will consider submissions across unicellular and cell-cluster organisms: prokaryotes (bacteria, archaea) and eukaryotes (fungi, protists, microalgae, lichens), as well as viruses and prions infecting or interacting with microorganisms, plants and animals, including genetic, biochemical, biophysical, bioinformatic and structural analyses. The journal features Original Articles (including full Research articles, Method articles, and Short Communications), Commentaries, Reviews, and Editorials. Original papers must report well-conducted research with conclusions supported by the data presented in the article. We also support confirmatory research and aim to work with authors to meet reviewer expectations. MicrobiologyOpen publishes articles submitted directly to the journal and those referred from other Wiley journals.
