Summary
The overuse of antibiotics in human and animal health has been favoring antibiotic resistance in bacteria. Moreover, antibiotic-resistance genes can spread in microbial communities, between bacteria, either pathogenic or commensal, by mobile genetic elements. The rise of aquaculture farms, to overcome the growing demand for fresh fish, can lead to the overuse of antibiotics to control diseases and promote growth. This work presents a first snapshot of the antibiotic resistance genes that are present in the sediments of oyster-extensive and gilthead bream semi-intensive aquacultures located in estuaries of three important rivers in the north, center, and south of Portugal. The metagenomic analysis approach revealed that the most diverse categories of antibiotic resistance are macrolide, tetracycline, and oxazolidinone classes. These resistances can hamper the effective treatment of infections in humans if transmitted through the food chain.
