Antibiotic Resistance and Aquatic Systems: Importance in Public Health

This review focuses on the crucial role of aquatic ecosystems in preserving biodiversity and the biosphere, as well as the connection between antimicrobial resistance (AMR) and these ecosystems. It provides an in-depth analysis of the link between ecological well-being and public health, helping readers understand this complex subject. Aquatic ecosystems are essential for maintaining biodiversity and ecological balance. Additionally, they act as primary reservoirs and pathways for the spread of antimicrobial resistance (AMR). These ecosystems risk antibiotic contamination through various sources, such as the release of antibiotics from animal and human waste, improper disposal of unused medications, and pharmaceutical industry waste management practices. The presence of antibiotic residues in these environments significantly speeds up the development of bacterial resistance. The global prevalence of antimicrobial resistance (AMR) is evident in freshwater bodies, tributaries, sewage waters, and wastewater treatment facilities. Antimicrobial resistance (AMR) is now a significant public health threat, compromising the effectiveness of many previously successful treatments against various pathogens. One notable and alarming aspect of antimicrobial resistance (AMR) is its rapid development, often occurring within 5–10 years after introducing antimicrobial drugs to the market. This acceleration is closely tied to bacteria’s ability to thrive and adapt in the presence of antimicrobial agents and their residues in the environment. The implications of antimicrobial resistance (AMR) include treatment failures with long-term effects and a continuous increase in healthcare costs. This review comprehensively examines the intricate relationship between aquatic habitats, antibiotics, and the global challenge of antimicrobial resistance (AMR). It emphasizes the critical role of these ecosystems in preserving ecological diversity. It raises awareness about AMR’s urgent public health issue, laying a foundation for understanding its extensive consequences.
