Abstract
Objectives
This study aimed to characterize Aeromonas veronii CTe-01 focusing on its resistance to heavy metal and antibiotics.
Methods
A. veronii CTe-01 was characterized using standard microbiological and molecular techniques. Antibiotic susceptibility and heavy metal resistance were tested per standard protocols. Genomic analysis, including plasmid characterization, was conducted in silico.
Results
A. veronii CTe-01 showed resistance to various heavy metals and antibiotics. Multiple resistance genes were identified, including those for beta-lactamases, heavy metal resistance, and type III secretion system components. The bacterium carries a 9 kb plasmid with repA/repB replication genes, parA/parB partitioning genes, and a type II toxin-antitoxin system for stability.
Conclusions
A. veronii CTe-01 is a genetic reservoir for antibiotic resistance, heavy metal resistance genes, and virulence factors. The study offers insights into its dual role as a pathogen and heavy metal remediator in aquatic environments.
