Characterization of Antibiotic Resistance E. Coli and Antibiotic Resistance Genes in Aquatic Environment of Taihu Lake, China

Abstract:

The aims of this study are to evaluate multiple antibiotic resistant Escherichia coli isolated from surface water and to investigate the presence and distribution antibiotic resistance genes (ARGs) in sediments of Taihu Lake. The results show that the presentence of four ARGs concentrations in the sediments of the lake was in sequence: strB>qnrB>strA>qnrS, as determined by realtime-PCR technique. The southwest and east areas of Taihu Lake were polluted seriously than other areas from all kinds of antibiotics. The screening Escherichia coli had a higher resistance to streptomycin, tetracycline and ampicillin than other four antibiotics, and had a lowest resistance to levofloxacin.
