Antibiotics and Resistance Genes in Awash River Basin, Ethiopia

In this study, the occurrence of three groups of antimicrobials including tetracycline, sulfonamides and fluoroquinolone, and their corresponding ARGs were investigated in the sediments of Awash River Basin, Ethiopia. Out of twelve studied compounds, sulfadiazine and enrofloxacin showed the highest and lowest detection frequency, respectively. Polymerase chain reaction (PCR) analysis revealed thattetA andtetB occurred in all the samples. The relative abundance of the resistant genes was in the following order:tetA  >  tetB  >  sul2  >  sul1. Redundancy analysis result indicated that some sediment characteristics were found to have influence on the distributionsul1-resistant gene.
