“…From Fig. 3, the detected ARGs in soil applied with swine wastewater were at high copy numbers, consistent with other studies (Wu et al, 2010;Cheng et al, 2015), which reflected the transfer of ARGs from animal farm to the surrounding environment.…”

“…Obviously, the distribution of ARGs was different between digested swine wastewater and the applied soil. The tetG increased in swine wastewater treated soil was noticed by Cheng et al (2015). Similarly, Peng et al (2015) found that tetG was the most abundance ARG in manure-treated soil, and tetG in soil increased by pretreatment with fresh manure by composting.…”

“…Similarly, Tang et al (2015) reported that tetG, sul1 and sul2 had high relative abundance with average values ranging from 1E-04 to 1E-03 copies/16S rRNA in long-term manured red soils. Besides, the persistent ARGs of tetG and sul1 detected in soil applied with digested swine wastewater was also reported by Cheng et al (2015), which requires more attention.…”

“…Different from solid manure, swine wastewater is applied frequently to meet the growth of vegetables and influenced by local climate (Cheng et al, 2015). Application of swine wastewater to farmland is a major route of dissemination of ARGs to environment, which increased the ARGs level in soil and also in runoff (Ghosh and LaPara, 2007;Joy et al, 2013).…”

“…The dominant factors influencing the retardation of antibiotics in soil include soil pH, SOM content, and soil texture (Thiele-Bruhn et al, 2004;Du and Liu, 2012). Antibiotic residues are less bioavailable, and thus less biodegradable in soils with high SOM and clay content, owing to stronger sorption to SOM and the formation of non-extractable residues (Luo et al, 2011;Müller et al, 2013;Cheng et al, 2016). Both higher SOM content and higher contents of enrofloxacin, oxytetracycline and sulfamethoxazole residues coincided in irrigated fields.…”

A metagenomic study was conducted to investigate the impact of raw wastewater use for irrigation in urban agriculture on the development of bacterial resistance in soil. Soil samples were collected in two African countries, from three different cities (each with irrigated and non-irrigated plots). Basic physical and chemical analysis were conducted, and the presence of selected antibiotic residues was assessed. Microbial DNA was extracted, quantified and sequenced. Microbial population structure and function, presence of horizontally transferable antibiotic resistance genes and Enterobacteriaceae plasmids replicons were analysed using bioinformatics. The relative prevalence of Proteobacteria and Bacteroidetes and sequence reads coding for microbial adaptation and growth were higher in irrigated fields; 33 and 26 transferable ARGs were found in irrigated and non-irrigated fields sequence reads, respectively. Extended spectrum β-lactam genes identified in irrigated fields included bla CARB-3, bla OXA-347, bla OXA-5 and bla Rm3. Concentration of sulfamethoxazole, ciprofloxacin and enrofloxacin in soils influenced the selection of antibiotic resistance genes encoding resistance against amphenicol, β-lactams, and tetracyclines. Ten Enterobacteriaceae plasmid amplicon groups were identified in the fields, five were common to both, two (IncW and IncP1) and three (IncY, IncFIB and IncFIA) were found in irrigated and non-irrigated fields, respectively.In conclusion, wastewater irrigation affected both soil microbial diversity and functions. Irrigated fields have more diverse transferable antibiotic resistance genes, including ESBL genes that encode resistance to βlactams antibiotics, except cephamycins and carbapenems. Even more, critical concentrations of antibiotic residues select for multiple and cross resistance. The findings from African cities show that wastewater irrigation in urban agriculture presents a serious public health risk for farmworkers and consumers by spread of bacterial resistance.
