Summary: Most bacteria exist and interact within polymicrobial communities, producing unique compounds, increasing virulence, and enhancing antibiotic resistance. This study demonstrates that changes in the growth environment can determine the final population composition of bacteria, highlighting the importance of considering the growth environment in understanding bacterial coexistence. The researchers also found that altering the carbon source in the growth media impacts the absolute growth of bacterial species and their dominance in co-culture. Furthermore, perturbing the spatial structure in the community can affect the relationship between growth and population composition.

Summary: When two clinically relevant bacterial pathogens, Staphylococcus aureus and Pseudomonas aeruginosa, co-culture in a biofilm, P. aeruginosa shows higher motility and lower pigment production, while S. aureus exhibits increased persistence due to lower abundances of proteins related to cell wall biosynthesis and cell division. Both species also display higher antimicrobial tolerance when co-cultured. This study provides insights into the dynamics of both the surfaceome and exoproteome of the dual-species biofilms.

Summary: This study demonstrates that Staphylococcus aureus relies on the presence of wall teichoic acids (WTA) and lipopolysaccharide (LPS) to hitchhike motile bacteria like Pseudomonas aeruginosa for movement. The hitchhiking motility of S. aureus is reduced when the gene encoding the WTA synthesis enzyme, TagO, is deleted, but restored when the gene is complemented. The study also shows that P. aeruginosa promotes the movement of S. aureus in the digestive system of Caenorhabditis elegans and mice.

Summary: This study investigated the variations in microbial communities associated with PM10 in three urban sites in Rome and their local sources. Bacterial and fungal communities in the air had the highest alpha-diversity and were separate from epiphytic and road dust communities. The resuspension/deposition of road dust from traffic was found to be a major source of microbial exchanges. The abundance of extremotolerant microbes in epiphytic communities increased with pollution levels and was associated with opportunistic human pathogenicity in fungal communities.

Summary: Nanomaterials, particularly zinc oxide (ZnO) nanostructures, are being widely studied in medicine due to their unique properties. However, recent research has shown that ZnO nanoparticles (ZnO-NPs) and ZnO nanorods (ZnO-NRs) can induce cellular toxicity. This study aimed to investigate the effects of ZnO-NR treatment on normal and cancer cells. The results demonstrated that ZnO-NR treatments led to cell death, activation of hypoxia response, and induction of autophagy and mitophagy. While ZnO-NRs showed potential in reducing cancer growth, concerns were raised regarding their impact on normal cells in the long term.

Summary: The emergence of multidrug-resistant bacteria is a growing threat to public health, necessitating the development of non-antibiotic antibacterial approaches. In this study, vertically aligned carbon nanotubes (VA-CNTs) with controlled nanomorphology were proposed as effective platforms for bacteria eradication. Through a combination of microscopic and spectroscopic techniques, the topography of VA-CNTs was tailored in a controlled and time-efficient manner using plasma etching processes. The highest reduction in cell viability was observed for VA-CNTs modified using plasma etching with Ar and O-2, indicating their potential as a surface for inactivating both planktonic and biofilm infections.

Summary: This study investigates the probiotic potential of an autochthonous Lactiplantibacillus plantarum strain (PFA2018AU) isolated from carrots in Abruzzo, Italy. The strain exhibits high survival under simulated gastro-intestinal conditions, low antibiotic susceptibility, hydrophobicity, aggregation, and the ability to inhibit the growth of several pathogens. In vivo experiments using Caenorhabditis elegans as a model organism demonstrate that L. plantarum PFA2018AU colonizes the gut, extends lifespan, and stimulates innate immunity. These findings suggest that LAB from vegetables like carrots have functional properties that make them potential novel probiotic candidates.
