Artificial Intelligence-Driven Analysis of Antimicrobial-Resistant and Biofilm-Forming Pathogens on Biotic and Abiotic Surfaces

Antibiotics, Journal Year: 2024, Volume and Issue: 13(8), P. 788 - 788

Published: Aug. 22, 2024

The growing threat of antimicrobial-resistant (AMR) pathogens to human health worldwide emphasizes the need for more effective infection control strategies. Bacterial and fungal biofilms pose a major challenge in treating AMR pathogen infections. Biofilms are formed by pathogenic microbes encased extracellular polymeric substances confer protection from antimicrobials host immune system. also promote growth antibiotic-resistant mutants latent persister cells thus complicate therapeutic approaches. ubiquitous cause serious risks due their ability colonize various surfaces, including tissues, medical devices, food-processing equipment. Detection characterization crucial prompt intervention control. To this end, traditional approaches often effective, yet they fail identify microbial species inside biofilms. Recent advances artificial intelligence (AI) have provided new avenues improve biofilm identification. Machine-learning algorithms image-processing techniques shown promise accurate efficient detection biofilm-forming microorganisms on biotic abiotic surfaces. These advancements potential transform research clinical practice allowing faster diagnosis tailored therapy. This comprehensive review focuses application AI identification industries, healthcare, food safety, agriculture. discusses existing approaches, challenges, applications research, with particular focus role improving diagnostic capacities guiding preventative actions. synthesis current knowledge future directions, as described review, will guide development efforts combating biofilm-associated

Bacteria-Inspired Synthesis of Silver-Doped Zinc Oxide Nanocomposites: A Novel Synergistic Approach in Controlling Biofilm and Quorum-Sensing-Regulated Virulence Factors in Pseudomonas aeruginosa

Antibiotics, Journal Year: 2025, Volume and Issue: 14(1), P. 59 - 59

Published: Jan. 9, 2025

Multidrug-resistant Pseudomonas aeruginosa infections pose a critical challenge to healthcare systems, particularly in nosocomial settings. This drug-resistant bacterium forms biofilms and produces an array of virulent factors regulated by quorum sensing. In this study, metal-tolerant bacteria were isolated from metal-contaminated site screened for their ability synthesize multifunctional nanocomposites (NCs). Rapid color changes the reaction solution evidenced biotransformation process. The potent Bacillus cereus SASAK, identified via 16S rRNA sequencing deposited GenBank under accession number MH885570, facilitated microbial-mediated synthesis ZnO nanoparticles silver-doped NCs. These biogenic characterized using UV-VIS-NIR spectroscopy, FTIR, XRD, zeta potential, HRTEM, FESEM, EDX analyses. At sub-MIC concentration 100 µg/mL, 2% Ag-ZnO NCs effectively inhibited factor production biofilm formation P. without affecting bacterial growth. Notably, there was significant reduction violacein pigment (96.25%), swarming motility, pyocyanin (1.87 µg/mL). Additionally, (81.1%) EPS (83.9%) substantially hindered, along with reduced extracellular protease activity, as indicated zone (from 2.3 1.8 cm). study underscores potential promising agents combating sensing-mediated virulence chronic caused multidrug-resistant aeruginosa.
