Copper Stress Response of Antibiotic‐Resistant and Copper‐Tolerant Enterococcus faecium and the Antibacterial Efficacy of Functionalized Copper Surfaces

Advanced Materials Interfaces, EarlyView.
This study examines how different laser‐patterned copper and brass surfaces, including copper coatings, affect the survival of vancomycin‐resistant Enterococcus faecium. Using microscopy and genome analysis, the results show that copper tolerance varies between strains and can increase after vancomycin exposure.

A Rare Case of a Distal Humerus Pathological Fracture from Klebsiella Pneumoniae Osteomyelitis: A Case Report [PDF]

Malaysian Orthopaedic Journal, 2020
Klebsiella pneumoniae is one of the leading causative organisms in pyogenic liver disease. It can cause disseminated infections, but rarely to bone, and rarely in healthy hosts. We report an unusual case of a distal humerus fracture from osteomyelitis

Antimicrobial Multi‐Assay Evaluation of (Al‐Doped ZnO)‐Ag and TiO2‐Ag Nanocoatings: Impact of Direct and Indirect Mechanisms

Advanced Materials Interfaces, EarlyView.
This work explores the antimicrobial action of AZO‐Ag and TiO2‐Ag nanocoatings on plastic, demonstrating good efficacy against highly‐critical antibiotic‐resistant bacteria, yeast, and virus. A multi‐assay approach is here exploited to inspect the contribution of direct and indirect antimicrobial mechanisms, and potential human toxicity is also ...

Detection Of clbB and clbN Genes in Isolated Klebsiella Pneumoniae of Biopsies from Colorectal Cancer Patient in Erbil Province

Eurasian Journal of Science and Engineering, 2023
Recently, it has been proved that some of Enterobacteriaceae like Klebsiella pneumoniae, which carry polyketide synthase (PKS) islands, damage human dsDNA by encoding Colibactin genotoxin; and finally, they induce some apoptosis in damaged mucosal cells.

Gallium β‐Cyclodextrin Nanoparticles Containing both Gallium Protoporphyrin and Gallium Nitrate Exhibit Antimicrobial Activity against Nontuberculous Mycobacteria in Vitro and in Vivo

Advanced Therapeutics, EarlyView.
Cyclodextrin nanoparticle containing both Ga(NO3)3 and GaPP is synthesized and tested against non‐tuberculous mycobacteria (NTM). The in vivo efficacy of the nanoparticle therapy is additionally tested by treating pulmonary NTM infections in mice and observed much greater effectiveness in bacterial clearance and survival of mice.
