Summary: This study determined the lethal concentrations of disinfectants and antibiotics for Listeria monocytogenes and found that the surface characteristics of bacterial cells influence resistance to these compounds. Most strains showed resistance to antibiotics, highlighting the concern of antibiotic resistance.

Summary: This study investigated the antimicrobial properties of differently sized AgNPs immobilized on a surface. It was found that an active surface with high antibacterial efficacy could be achieved using a small amount of silver, reducing aggregation phenomena. The research provides a pathway for the development of antibacterial materials with low silver content.

Summary: By artificially creating a density gradient of selenium concentration, we successfully achieved simultaneous fabrication of two superstructures of CuSe monolayer on a Cu(111) substrate and observed an intermediate state. Scanning tunneling microscopy and spectroscopy measurements showed that the selenium concentration can modulate the superstructure and semiconductor behavior of the CuSe monolayer.

Summary: In this study, an Epinecidin called Em-Epi was identified and functionally characterized from the Malabar grouper. Em-Epi showed similar physico-chemical properties and sequence identity with Epinecidin from Epinephelus coioides. Functional characterization revealed that Em-Epi has antibacterial, antiviral, and anticancer activities.

Summary: Antimicrobial peptides (AMPs) are potential candidates for replacing conventional antibiotics to combat drug resistance in pathogenic bacteria. To accelerate the evaluation process, we develop a deep learning method called MBC-Attention to predict the minimum inhibitory concentration of AMPs against Escherichia coli. The proposed model outperforms traditional machine learning methods.

Summary: In this study, a method to examine the antimicrobial and bactericidal activities of AMPs at the single-cell level was developed and applied to analyze the interaction between an AMP called magainin 2 (Mag) and Escherichia coli cells. The results show that a short interaction time is sufficient to induce bacterial cell death.

Summary: There is currently no internationally accepted, standardized method for determining the minimum inhibitory concentration (MIC) of natural substances like essential oils. This study aimed to compare MIC values obtained from different studies that used various culture media. The results showed that the MIC values for cinnamon essential oil varied depending on the culture media used, with the median values ranging from 465 to 517 μg/mL. The MIC values for oregano essential oil were significantly lower in Mueller-Hinton Broth (MHB) compared to highly nutritious media. Additionally, the lag phase of bacterial growth in the presence of oregano essential oil was much shorter in MHB compared to other media. Therefore, MHB is not recommended for comparing the antimicrobial properties of different essential oils.

Summary: Although antibiotic treatment cannot eradicate avian mycoplasmosis, it can reduce the number of deaths. One major challenge of antibiotic treatments is the development of antimicrobial resistance among field isolates. Regular determination of minimum inhibitory concentrations of antibiotics is necessary to optimize treatment dosages.

Summary: By using a machine learning feature selection approach, we accurately predicted the minimum inhibitory concentration (MIC) values of antimicrobial drugs, and found that half of the selected features were annotated as hypothetical proteins with unknown functions, indicating the potential of uncovering novel genes associated with pathogenic antimicrobial resistance through feature selection on the entire gene set.

Summary: This study synthesized Cu:Ag bimetallic nanoparticles and evaluated their characterization and antibacterial properties, revealing significant inhibition effects against bacteria such as Staphylococcus aureus and Escherichia coli with different concentrations of Ag. The findings suggest the potential of Cu-Ag bimetallic NPs as inhibitors of certain enzymes, indicating new opportunities for antibiotic discovery through in vitro studies.
