TL;DR: The S.flexneri chromosome has, astonishingly, 314 IS elements, more than 7-fold over those possessed by its close relatives, the non-pathogenic K12 strain and enterohemorrhagic O157:H7 strain of Escherichia coli.

TL;DR: Evidence is presented that extracellular DNA is important for the initial phase of biofilm development by S. epidermidis on polystyrene or glass surfaces under static or hydrodynamic conditions, and that the ext racellular DNA promotes biofilm formation of the remaining population.

TL;DR: The complete genome of Staphylococcus epidermidis strain ATCC 12228, a non‐biofilm forming, non‐infection associated strain used for detection of residual antibiotics in food products, was sequenced and the ica operon coding for the enzymes synthesizing interbacterial cellular polysaccharide is missing.

TL;DR: In this paper, the authors performed a genome-wide CRISPR screen and identified several endosomal entry-specific regulators, including host factors regulating the surface expression of angiotensin-converting enzyme 2 (ACE2) for SARS-CoV-2.

TL;DR: A decoy nanoparticle is reported against COVID-19 through a powerful two-step neutralization approach: virus neutralization in the first step followed by cytokine neutralizationIn the second step, the nanodecoys efficiently bind and neutralize inflammatory cytokines including interleukin 6 (IL-6) and granulocyte−macrophage colony-stimulating factor (GM-CSF), and significantly suppress immune disorder and lung injury in an acute pneumonia mouse model.
