1996年夏に多発した腸管出血性大腸菌O157感染症は医学的,細菌学的のみならず社会的な問題ともなった.本年になっても多くの集団例,散発例が報告され,けっして我々のまわりからO157の危険が去ったわけではない. O157感染症の大きな問題点はその病態が単なる食中毒のような腸管感染症にとどまらず, HUSや脳症のような重篤な合併症を併発し全身性感染症的要素を有すること,また合併症に対する有効な治療法が確立していないことである.

The newfound relationship between extrachromosomal DNAs and excised signal circles
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Metagenomic characterisation of additional and novel avian viruses from Australian wild ducks
Birds, notably wild ducks, are reservoirs of pathogenic and zoonotic viruses such as influenza viruses and coronaviruses. In the current study, we used metagenomics to detect and characterise avian DNA and RNA viruses from wild Pacific black ducks ...

レジオネラは土壌細菌で世界中に分布しているが,近代の文化的生活における人工環境の至る所で増殖し,近年新たな展開を見せている.特に,人工環境水においては共存するアメーバを媒体として大量に増殖し,ありとあらゆる環境水からレジオネラ感染の危険性が高まっている.人工環境水の消毒の問題は人体への影響を考慮する必要があり,困難をきわめている状態である.わが国にはビル管理基準としての冷却塔におけるレジオネラ症防止指針が作成されているが,米国のCDCのような院内感染防止指針やその他の環境水に対する水の管理基準の策定はこれからである.診断法はPCR法や尿中抗原検出などかなりの進歩が見られているので,疑わしい症例では積極的にしかるべき施設へ依頼してでも確定診断を得る努力をする必要がある.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Antibody-Dependent Dengue Virus Entry Modulates Cell Intrinsic Responses for Enhanced Infection
Dengue is caused by infection with any one of four dengue viruses (DENV); the risk of severe disease appears to be enhanced by the cross-reactive or subneutralizing levels of antibody from a prior DENV infection.

A comprehensive genomic and proteomic analysis of cervical cancer revealed STK11 and STX3 as a potential biomarkers of chemoradiation resistance. Our study demonstrated EGFR as a therapeutic target, paving the way for precision strategies to overcome treatment failure and the DNA repair pathway as a critical mechanism of resistance.
