One‐Step Immobilized Phage Depolymerase Coatings for Catheter‐Related Bloodstream Infections

Advanced Science, EarlyView.
Catheter‐related bloodstream infections (CRBSI) caused by drug‐resistant Gram‐negative bacteria remain a major clinical challenge. Here, a polydopamine‐assisted depolymerase coating degrades bacterial capsules and restores serum‐mediated killing, effectively suppressing biofilms and reducing bacterial burden in vitro, ex vivo, and in vivo, presenting a

A study of Clostridium difficile in biofilm mode of growth using the Sorbarod filter system [PDF]

In all ecosystems, bacteria are likely to grow in biofilms, and the organisms making up the natural flora of the colon are considered to be no exception to this. One of the most important hospital-acquired infections is antibiotic associated diarrhoea,

Anti-biofilm potential of phenolic acids: the influence of environmental pH and intrinsic physico-chemical properties

, 2016
Phenolic acids are a particular group of small phenolic compounds which have exhibited some anti-biofilm activity, although the link between their activity and their intrinsic pH is not clear.

Reversing Macrophage Immunometabolic Dysfunction in Prolonged Infections Via a Glutaminolysis‐Fueled Restoration‐Based Hierarchically Selective Therapeutic System

Advanced Science, EarlyView.
A hierarchically selective immunotherapeutic nanoplatform, mGls@HEV‐MTP, selectively restores macrophage immunocompetence through GLS1‐mediated restoration of glutaminolysis‐fueled anaplerosis. Concurrently, it renders Staphylococcus aureus (S. aureus) more readily recognizable to the metabolically reprogrammed macrophages, thereby facilitating ...

Antibiofilm Activity of Areca Nut (Areca catechu L.) Extract and Fractions against Escherichia coli ATCC 25922

Journal of Nuts
Escherichia coli is one of the pathogenic bacteria that is resistant to antibiotics. Antibiotic resistance does not only occur due to antibiotics failing, but changes in the bacteria themselves also play an important role.

Integrated transcriptomic and metabolomic analysis of the antibacterial mechanism of Rhizoma Coptidis extract against Staphylococcus epidermidis ATCC 35984

BMC Microbiology
Background Biofilm formation is a key virulence factor in Staphylococcus epidermidis. Rhizoma Coptidis, the medicinal root of Coptis chinensis, has been traditionally used in Chinese medicine for its broad-spectrum antimicrobial properties.

Noncanonical Peloruside A Biosynthesis by an Uncultivated Verrucomicrobiota Symbiont

Angewandte Chemie, EarlyView.
Noncanonical biochemistry of the peloruside PKS characterized in this work, comprising double bond generation by a noncanonical tridomain (blue), acetyl‐CoA recycling (orange), and proofreading systems (purple and yellow). The Z‐double bond is installed by TEB1 through O‐acetylation and acetate elimination. The acyl ligase PelB (AL, orange) selectively
