Efficacy of copper-impregnated antimicrobial surfaces against spores.
Infect Control Hosp Epidemiol
December 2024
Objective: () is one of the most common causes of healthcare-associated infections (HAIs). Elimination of spores is difficult as they are resistant to common hospital-grade disinfectants. Copper-impregnated surfaces provide continuous reduction of multiple pathogens, potentially lowering the risk of infections.

- Peripheral nerve-crush injury promotes neuromuscular junction (NMJ) recovery, showing improved muscle function as nerve re-innervates, while volumetric muscle loss (VML) leads to permanent muscle function loss and chronic NMJ impairments.
- In a study with adult mice, researchers compared the effects of nerve-crush versus VML on NMJ remodeling, monitoring recovery over time post-injury.
- Results indicated that while nerve-crush injury allowed for complete recovery of muscle strength, VML resulted in persistent deficits, along with abnormal signaling and structural changes at the NMJ, with some noted sex differences in recovery rates.
Background: Microbial contamination of hospital surfaces remains despite adherence to routine disinfection. Our study demonstrates bioburden from various types of hospital high-touch surfaces and the pathogenicity of all bacteria recovered.
Methods: Several high-touch hospital surfaces from a single medical-surgical unit were sampled and cultured using replicate organism detection and counting (RODAC) Tryptic Soy agar plates.
We report extensively drug-resistant (XDR) Shigella sonnei infection in an immunocompromised patient in Texas, USA. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry failed to identify XDR Shigella, but whole-genome sequencing accurately characterized the strain. First-line antimicrobials are not effective against emerging XDR Shigella.

The objective of this study was to evaluate the device's ability to kill microbial pathogens on hospital surfaces and compare it to manual disinfection using germicidal sodium hypochlorite wipes.
Methods: A total of 344 observations (4 observations from 86 objects' surfaces) were sampled with 2 paired samples per surface: a pre- and a post-sodium hypochlorite and FFUV sample.
