Migration and degradation of swine farm tetracyclines at the river catchment scale: Can the multi-pond system mitigate pollution risk to receiving rivers?
Abstract
The study investigated the degradation behaviors of swine farm tetracyclines (TCs) at a catchment scale and explored whether multi-pond systems could be beneficial to the interception of TCs so as to reduce the pollution risk to receiving rivers. The occurrence and migration of 12 kinds of tetracycline antibiotics, including their degradation products, were studied in four swine farms of the Meijiang River basin in China. The migration paths of the TCs were examined through sampling and analyzing the soil and/or sediment at different points along the swine wastewater outlet, which included sewer, sewage p...

Tracking antibiotic resistance gene transfer at all seasons from swine waste to receiving environments
Ecotoxicol Environ Saf. 2021 May 18;219:112335. doi: 10.1016/j.ecoenv.2021.112335. Online ahead of print.ABSTRACTAntibiotic resistance genes (ARGs) in livestock farms have attracted a growing attention with potential effects on human health. As one of the most important organic fertilizer, swine waste provided an ideal environment for understanding the dissemination and accumulation of ARGs in agricultural ecosystems. Here we conducted a year-round follow-up trace from swine waste to receiving environments, with the purpose of revealing the contamination profiles and ecological risks of ARGs at different seasons. Results i...

Biodegradation of three tetracyclines in swine wastewater.
In this study, we investigated the biodegradation of three TCs in swine wastewater. In batch experiments, OTC and CTC were completely degraded at d 18 and 20, respectively, but TC was remained at 7.1% after 20 d incubation. The degradation rates of TCs in the wastewater were in the order of OTC > CTC > TC. Degradation of the TCs was enhanced by the addition of enzyme extract from spent mushroom compost (SMC) of Pleurotus eryngii. The degradation rates were higher with the addition of extract-containing microcapsules than suspended enzyme extract in swine wastewater. In the bioreactor experiment, the addition of extra...

Sorption of tetracycline on H3PO4 modified biochar derived from rice straw and swine manure.
Abstract
Currently, the information about the sorption of tetracycline (TC) on animal manure derived biochar was rare although plant residue derived biochar showed high sorption of TC). Therefore, this study explored the sorption of TC on swine manure derived biochar, and compared with rice straw derived biochar simultaneously. Also, H3PO4 was adopted to modify both types of biochar. The sorption kinetic and isotherm data showed H3PO4 modification enhanced the sorption of TC on both types of biochar (especially swine-manure-biochar), and indicated the chemisorptions including H-bonding and π-π electron donor acc...

Interaction of swine organic anion transporting polypeptide 1a2 with tetracycline, macrolide and β-lactam antibiotics.
Abstract
Organic anion-transporting polypeptides (human OATPs; animals Oatps; gene symbol SLCO/Slco) are integral membrane proteins that mediate the sodium-independent transport of a wide range of endogenous compounds as well as many xenobiotics. Antibiotics, antidiabetic drugs, anti-inflammatory drugs, antifungals, antivirals, antihistamines, antihypertensives, fibrates, statins, cardiac glycosides, immunosuppressants, and anticancer drugs are among the substrates transported by OATPs. Because of the broad substrate specificity, wide tissue distribution and the involvement of drug-drug interaction, human OATPs ha...

Tissue concentrations of sulfamethazine and tetracycline hydrochloride of swine (Sus scrofa domestica) as it relates to withdrawal methods for international export.
In conclusion, the TLM may not always provide adequate WDT for foreign export markets especially when MRLs differ from tolerance levels approved for US markets. However, PopPK methods can provide conservative WDIs in situations with considerable variability in medication exposure such as with administration in water.

Swine Farming Is a Risk Factor for Infection With and High Prevalence of Carriage of Multidrug-Resistant Staphylococcus aureus
Conclusions. Current swine workers are 6 times more likely to carry MDRSA than those without current swine exposure. We observed active infections caused by LA-SA. This finding suggests that individuals with livestock contact may have a high prevalence of exposure to, and potentially infection with, antibiotic-resistant S. aureus strains, including LA-SA strains.

Seasonal variation and removal efficiency of antibiotic resistance genes during wastewater treatment of swine farms.
Abstract
The seasonal variation and removal efficiency of antibiotic resistance genes (ARGs), including tetracycline resistance genes (tetG, tetM, and tetX) and macrolide (ermB, ermF, ereA, and mefA), were investigated in two typical swine wastewater treatment systems in both winter and summer. ARGs, class 1 integron gene, and 16S rRNA gene were quantified using real-time polymerase chain reaction assays. There was a 0.31-3.52 log variation in ARGs in raw swine wastewater, and the abundance of ARGs in winter was higher than in summer. tetM, tetX, ermB, ermF, and mefA were highly abundant. The abundance of ARGs was...
