Airborne bacterial community and antibiotic resistome in the swine farming environment: Metagenomic insights into livestock relevance, pathogen hosts and public risks
Environ Int. 2023 Jan 13;172:107751. doi: 10.1016/j.envint.2023.107751. Online ahead of print.ABSTRACTGlobally extensive use of antibiotics has accelerated antimicrobial resistance (AMR) in the environment. As one of the biggest antibiotic consumers, livestock farms are hotspots in AMR prevalence, especially those in the atmosphere can transmit over long distances and pose inhalation risks to the public. Here, we collected total suspended particulates in swine farms and ambient air of an intensive swine farming area. Bacterial communities and antibiotic resistomes were analyzed using amplicon and metagenomic sequencing app...

Characteristics of aerosols from swine farms: A review of the past two-decade progress
Environ Int. 2023 Jul 1;178:108074. doi: 10.1016/j.envint.2023.108074. Online ahead of print.ABSTRACTWith the rapid development of large-scale and intensive swine production, the emission of aerosols from swine farms has become a growing concern, attracting extensive attention. While aerosols are found in various environments, those from swine farms are distinguished from human habitats, such as residential, suburban, and urban areas. In order to gain a comprehensive understanding of aerosols from swine farms, this paper reviewed relevant studies conducted between 2000 and 2022. The main components, concentrations, and siz...

Novel Human-like Influenza A Viruses Circulate in Swine in Mexico and Chile
Discussion Through new surveillance efforts and phylogenetic analysis of IAV-S in Mexico and Chile, we have expanded our understanding of the extensive IAV-S diversity that circulates in swine in Latin America. Most notably, we have identified multiple novel clades of H3N2 and H1N1 viruses of human origin in Mexico and Chile that have not been identified in swine previously, highlighting the importance of the human-swine interface in the evolution of IAV-S diversity in Latin America. The presence of two different IAV-S lineages in Mexico that are related to North American IAV-S (classical H1N1 and H3-cluster IV) also demon...

Antibiotics in swine husbandry effluents: Laying the foundations for their efficient removal with a biocompatible ionic liquid
Publication date: 15 August 2016 Source:Chemical Engineering Journal, Volume 298 Author(s): M.S. Álvarez, L. Gómez, R.G. Ulloa, F.J. Deive, M.A. Sanromán, A. Rodríguez The presence of emerging contaminants such as antibiotics is currently urging the search of new techniques to efficiently remove them from the environment. In this work, the exceptional ability of a cholinium-based ionic liquid to salt out aqueous solutions of non-ionic surfactants containing tetracycline and oxytetracycline has been demonstrated. The deep characterization of the phase diagrams has allowed implementing the process with an antibio...

Search for Campylobacter reveals high prevalence and pronounced genetic diversity of Arcobacter butzleri in floodwater samples associated with Hurricane Florence, North Carolina, USA.
In this study, floodwater samples (n=96) were collected as promptly post-hurricane as possible and for up to approx. 30 days, and selectively enriched for Campylobacter using Bolton broth enrichment and isolation on mCCDA microaerobically at 42°C. Only one sample yielded Campylobacter, which was found to be Campylobacter jejuni with the novel genotype ST-2866. However, the methods employed to isolate Campylobacter readily yielded Arcobacter from 73.5% of the floodwater samples. The Arcobacter isolates failed to grow on Mueller-Hinton agar at 25, 30, 37 or 42°C microaerobically or aerobically, but could be readily subcult...

Metagenomics analysis of microbial community distribution in large-scale and step-by-step purification system of swine wastewater
Environ Pollut. 2022 Sep 8:120137. doi: 10.1016/j.envpol.2022.120137. Online ahead of print.ABSTRACTBiological treatment is one of the most widely used methods to treat swine wastewater in wastewater treatment plants. The microbial community plays an important role in the swine slurry treatment system. However, limited information is available regarding the correlation between pollutant concentration and dominant microbial community in swine wastewater. This work aimed to study the profiling of microbial communities and their abundance in the 40 M3/day large-scale and step-by-step treatment pools of swine wastewater. Metag...

Subacute Cadmium Exposure Induces Necroptosis in Swine Lung via Influencing Th1/Th2 Balance
Biol Trace Elem Res. 2022 Feb 3. doi: 10.1007/s12011-022-03133-6. Online ahead of print.ABSTRACTCadmium (Cd) is a type of toxic substance, which widely exists in nature. However, the effect of Cd exposure on the toxicity of swine lungs and its underlying mechanism involved have not yet been reported. In our study, we divided swine into two groups, including a control group (C group) and Cd-exposed group. Swine in the C group were fed a basic diet, whereas swine in the Cd group were fed a 20 mg Cd/kg diet. Immunofluorescence, qRT-PCR, western blot analysis, and H&E staining were performed to detect necroptosis-related i...

Removal of microorganisms and antibiotic resistance genes from swine wastewater: a comparison between polyaluminum chloride (PAC), polyaluminum sulfate (LST), and aluminum hydroxide iron (LT)
J Environ Sci Health B. 2022 Apr 5:1-8. doi: 10.1080/03601234.2022.2058844. Online ahead of print.ABSTRACTThe presence of antibiotic-resistant bacteria (ARB) and antibiotic-resistance genes (ARGs) in swine wastewater may present a threat to the environment and public health. Conventional swine wastewater treatment processes generally fail to effectively reduce the content of ARGs. Therefore, it is necessary to develop a highly efficient and low-cost treatment method to solve this environmental problem. In doing so, we evaluated the application of three common coagulants in the treatment of swine wastewater. Using metagenom...

Potential Zoonotic Swine Enteric Viruses: The Risk Ignored for Public Health
Virus Res. 2022 Apr 11:198767. doi: 10.1016/j.virusres.2022.198767. Online ahead of print.ABSTRACTSwine could serve as a natural reservoir for a large variety of viruses, including potential zoonotic enteric viruses. The presence of viruses with high genetic similarity between porcine and human strains may result in the emergence of zoonotic or xenozoonotic infections. Furthermore, the globalization and intensification of swine industries exacerbate the transmission and evolution of zoonotic viruses among swine herds and individuals working in swine-related occupations. To effectively prevent the public health risks posed ...
