The global rise in antimicrobial resistance (AMR) among bacteria causing infectious diseases is well documented, and the associated risks for human health are well known. There is much less research on AMR with regard to environmental strains, both opportunistic and pathogenic ones. The genus Aeromonas is widely distributed in the environment and causes many variable diseases in fish and humans. Infections in humans are predominantly caused by Aeromonas veronii, A. hydrophila and A. caviae (A. punctata) in a form of bacteremia, gastroenteritis or even septicaemia in immunocompetent and immunocompromised individuals. Different groups of antibiotics are used in the treatment, but studies indicate that fluoroquinolones and cefotaxime are the most efficient. A disturbing consequence of antibiotic overuse is an increasing number of detection of various antibiotic resistance genes (ARG) within this genus. The water environment is one of the major modes of transmission of resistant bacteria from animals to humans, and, thus, the dissemination of antibiotic resistance genes, particularly those located in mobile genetic elements (MGE) occurs in such as plasmids and transposons. This review summarizes recently published information on the type, distribution, and transmission of ARG by MGE, widespread in Aeromonas strains living in various aquatic environments, including wastewater, natural water, aquaculture and urban drinking water. The data available indicate that the opportunistic pathogens like Aeromonas spp. might serve as important vectors of ARG for clinically relevant pathogens present in such bodies of water .
