Abstract: | The use of antibiotics may accelerate the development of antibiotic resistance genes (ARGs) and bacteria which shade health
risks to humans and animals. The emerging of ARGs in the water environment is becoming an increasing worldwide concern. Hundreds
of various ARGs encoding resistance to a broad range of antibiotics have been found in microorganisms distributed not only
in hospital wastewaters and animal production wastewaters, but also in sewage, wastewater treatment plants, surface water,
groundwater, and even in drinking water. This review summarizes recently published information on the types, distributions,
and horizontal transfer of ARGs in various aquatic environments, as well as the molecular methods used to detect environmental
ARGs, including specific and multiplex PCR (polymerase chain reaction), real-time PCR, DNA sequencing, and hybridization based
techniques. |
