Bacterial Antibiotic and Heavy Metal Resistance Mechanisms
This community investigates the molecular mechanisms by which bacteria develop resistance to antibiotics and heavy metals, focusing on the genetic and physiological pathways that allow pathogens to survive in hostile environments.
The research centers on the interplay between antimicrobial resistance and metal tolerance in major pathogens such as Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa. Key mechanisms identified include the overexpression of efflux pumps, the modification of outer membrane proteins, and the management of oxidative stress. A significant portion of the work examines the co-selection of antibiotic and heavy metal resistance genes, particularly in environmental and clinical isolates. The community also explores the role of biofilm formation and membrane vesicles in facilitating the spread of these resistance traits. Specific attention is given to the genetic determinants of resistance in Mycobacterium tuberculosis and Klebsiella pneumoniae, as well as the development of novel antimicrobial agents and inhibitors targeting these resistance pathways.
The community’s output is distributed across multiple elements, with the largest shares of research found in cadmium (0.6%) and manganese (0.6%) studies. It also represents a significant portion of research tracked for zinc (0.3%) and copper (0.3%).
The community comprises 16,451 papers, with the highest publication volumes in Frontiers in Microbiology, the Journal of Bacteriology, and the Journal of Biological Chemistry.
Recent work includes the de novo design of antimicrobial peptides using deep learning, the investigation of heavy metal and antibiotic co-exposure in wastewater, and the repurposing of non-antibiotic drugs as antibacterial agents to combat resistance.
