Antimicrobial characteristics of metals reveal that Ag despite its economic constraints remains the most popular antibiotic agent. Antimicrobial characteristics of copper nanoparticles (CNPs) are not well understood. To our knowledge, no systematic comparative study on microbial properties of silver nanoparticles (SNPs) and CNPs exists. In this article, a comparative study on microbial properties of engineered metal nanoantibiotics against clinically important strains has been attempted. Our results indicate that biocidal activities of CNPs are better than SNPs. Minimum inhibitory concentration (MIC) values of CNPs are 10 times lower than the corresponding MICs of SNPs. These improved biocidal activities of CNPs would make it affordable and potent nontraditional antibiotics against which microbes are least susceptible to develop any drug resistance.

The microbial aminotransferase enzyme DapC is vital for lysine biosynthesis in various Gram-positive bacteria, including . Characterization of the enzyme's conformational dynamics and identifying the key residues for ligand binding are crucial for the development of effective antimicrobials. This study employs atomistic simulations to explore and categorize the dynamics of DapC in comparison to other classes of aminotransferase.

RNA viruses have high genetic diversity, allowing rapid adaptation to environmental pressures, such as disinfection. This diversity increases the likelihood of mutations influencing the viral sensitivity to disinfectants. Ethanol is widely used to control viral transmission; however, insufficient disinfection facilitates the survival of less-sensitive viruses.

Background: Multidrug-resistant bacteria (MDR) represent a significant global health concern and vary in specific settings. Spain reported several annual deaths attributed to MDR bacteria, mainly carbapenemase-producing Enterobacterales.
Objectives: We aimed to characterise the incidence and temporal trends of MDR bacterial infections or colonisations reported within the province of Granada (data from five hospitals), and to investigate factors linked to clinical vulnerability.

Tuberculosis (TB), a leading infectious disease caused by the pathogen , poses a significant treatment challenge due to its unique characteristics and resistance to existing drugs. The conventional treatment regimens, which are lengthy and involve multiple drugs, often result in poor patient adherence and subsequent drug resistance, particularly with multidrug-resistant (MDR) and extensively drug-resistant (XDR) strains. This highlights the urgent need for novel anti-TB therapies and new drug targets.
