“…The depth of sample did not portray a reasonable difference in the MRB content. Coliform and salmonella was reported found across the three sampled area [21]. The resistance of Pseudomonas aeruginosa isolated from plant samples against a range of antibiotics have also been reported.…”

“…Most of the isolated specie had resistance to ampicillin while no specie was reported to be resistant to sulfa methoxazol [20]. The soil samples of an active agricultural site [21] with different pattern of irrigation system have also been investigated for MRB presence. While a part of the agro site receives irrigation with untreated wastewater till the time of the investigation, another part of the site was never irrigated and irrigation was discontinued for the third part some years into their study.…”

Antibiotics are bioactive substances, used as human and animal medicines for illness prevention, disease treatment and growth promotion. They are considered to be pseudo persistent given their continuous input in the environment. Antibiotics enter agro ecosystems through several routes such as wastewater irrigation, soil application, animal manures or bio-solids which are mostly biologically active thus creating potential risks to the environment. They are present in different environmental matrices at low concentrations as residues. Antibiotic residues enter the environment primarily via urine, feces and manure from humans and animals after they have taken the medication, as well as from manufacturing wastewater. These residues contaminate the soil, surface water, and groundwater by leaching or runoff and ultimately breed antibiotic-resistant bacteria (ARB) and genes (ARG). These triune threat viz antibiotics, ARB and ARG have not been effectively removed by various treatment in wastewater treatment plants. Here, we put together existing knowledge and aim at providing in-depth knowledge to the extent to which a wide range of treatment processes determine the ultimate fate of antibioticbred threats (ARB and ARG) in conventional and advanced wastewater treatment. The use of antibiotics is inevitable, hence studies focusing on minimizing their discharge into the environment viz-a-viz support future regulatory measures are of great importance.

“…On the basis of the results of their experiments, it was established that about 94 strains of pathogenic flora were distinguished altogether in the test samples of the soil; the same tendency was inherent in the samples that were taken from nonirrigated soil. The use of raw wastewater for irrigation increases the development of resistibility of microorganisms, which can be observed even after a long period of time after the last irrigation [Palacios et al, 2017].…”

“…To prevent groundwater contamination by harmful pathogens in the future, it is critical to track microbial sources and evolution precisely and to address animal carcasses and manure as a source [ 13 ]. However, it is difficult to identify representative microorganisms in subsurface environments using conventional culturing methods.…”

Impacts of leachates from livestock carcass burial and manure heap sites on groundwater geochemistry and microbial community structure

et al. 2017

We investigated the impacts of leachates from a swine carcass burial site and a cow manure heap on the geochemical and microbiological properties of agricultural water samples, including leachate, groundwater from monitoring wells and background wells, and stream water. The leachate from the livestock burial site showed extremely high electrical conductivity, turbidity, and major ion concentrations, but low redox potential and dissolved oxygen levels. The groundwater in the monitoring wells adjacent to both sites showed severe contamination from the leachate, as indicated by the increases in EC, turbidity, Cl-, and SO42-. Bacteria from the phylum Firmicutes and Bacteriodetes and Archaea from the phylum Euryarchaeota were the major phyla in both the leachates and manure heap. However, the class- or genus-level components of these phyla differed markedly between the leachate and manure heap samples. The relative abundance of Firmicutes decreased from 35% to 0.3~13.9% in the monitoring wells and background wells at both sites. The Firmicutes in these wells was unlikely to have originated from the transportation of leachate to the surrounding environment because Firmicutes genera differed drastically between the leachate and monitoring wells. Meanwhile, sulfate-reducing bacteria (SRB) from the livestock carcass burial site were detected in the monitoring wells close to the leachate. This was likely because the release of carcass decomposition products, such as organic acids, to adjacent areas improved the suitability of the local environments for SRB, which were not abundant in the leachate. This study highlights the need to better understand microbial community dynamics along groundwater flow paths to evaluate bacterial transport in subsurface environments and provides new insights into the effective management of groundwater quality at both farm and regional scales.
