“…Much of the problem has been attributed to mobile genetic elements such as plasmids and transposons [ 2 ]. Integrons are genetic elements that also contribute to the prevalence and horizontal transmission of antibiotic resistance [ 3 , 4 , 5 ]. Integrons are genetic elements with a site-specific recombination system for capturing, expressing and exchanging gene cassettes [ 6 ].…”

“…Since such clinically important ARGs have been thought to be derived from anthropogenic activity, class 1 integron was also suggested as a proxy for anthropogenic pollution [ 112 ]. Besides, the presence of ARGs on class 2 integron structure was found in Enterobacteriaceae family in India, with dfrA1 - sat2 - aadA1 the most frequently detected [ 113 ]. Class 3 integron was detected with gene cassettes carrying bla OXA-256 and aac(6′)-Ib variants in Enterobacter cloacae from hospital effluent, suggesting it has possibly participated in dissemination of ARGs in clinical and environmental settings [ 114 ].…”

Since the first discovery of antibiotics, introduction of new antibiotics has been coupled with the occurrence of antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARGs). Rapid dissemination of ARB and ARGs in the aquatic environments has become a global concern. ARB and ARGs have been already disseminated in the aquatic environments via various routes. Main hosts of most of ARGs were found to belong to Gammaproteobacteria class, including clinically important potential pathogens. Transmission of ARGs also occurs by horizontal gene transfer (HGT) mechanisms between bacterial strains in the aquatic environments, resulting in ubiquity of ARGs. Thus, a few of ARGs and MGEs ( e.g. , strA , sul1 , int1 ) have been suggested as indicators for global comparability of contamination level in the aquatic environments. With ARB and ARGs contamination, the occurrence of critical pathogens has been globally issued due to their widespread in the aquatic environments. Thus, active surveillance systems have been launched worldwide. In this review, we described advancement of methodologies for ARGs detection, and occurrence of ARB and ARGs and their dissemination in the aquatic environments. Even though numerous studies have been conducted for ARB and ARGs, there is still no clear strategy to tackle antibiotic resistance (AR) in the aquatic environments. At least, for consistent surveillance, a strict framework should be established for further research in the aquatic environments.
