Occurrence of Staphylococcus aureus in swine and swine workplace environments on industrial and antibiotic-free hog operations in North Carolina, USA: A One Health pilot study.
Abstract Occupational exposure to swine has been associated with increased Staphylococcus aureus carriage, including antimicrobial-resistant strains, and increased risk of infections. To characterize animal and environmental routes of worker exposure, we optimized methods to identify S. aureus on operations that raise swine in confinement with antibiotics (industrial hog operation: IHO) versus on pasture without antibiotics (antibiotic-free hog operation: AFHO). We associated findings from tested swine and environmental samples with those from personal inhalable air samplers on worker surrogates at one IHO and thr...

Stage of Gestation at Porcine Epidemic Diarrhea Virus Infection of Pregnant Swine Impacts Maternal Immunity and Lactogenic Immune Protection of Neonatal Suckling Piglets
In this study, we infected pregnant first parity gilts in their first, second and third trimesters of gestation with PEDV to determine the impact of stage of gestation on generation of maternal B-cell immunity, the gut-MG-sIgA axis and lactogenic immune protection in PEDV challenged piglets. Our goal was to identify innate and adaptive immune factors during pregnancy that influence lymphocyte trafficking, in addition to immune correlates of lactogenic immune protection in neonatal suckling piglets. Understanding the impact of stage of gestation at PEDV infection or exposure on maternal immunity will allow more precise mate...

Development of a Reproducible Swine Model of Chronic Ischemic Mitral Regurgitation: Lessons Learned.
CONCLUSION: A reproducible percutaneous model of severe IMR in swine is feasible with a guided anesthetic and peri-operative approach. This model can serve as a platform to better understand the mechanism of IMR and subsequently to test novel repair techniques. PMID: 32553769 [PubMed - as supplied by publisher]

New Immunoinformatics Tools for Swine: Designing Epitope-Driven Vaccines, Predicting Vaccine Efficacy, and Making Vaccines on Demand
Novel computational tools for swine vaccine development can expand the range of immunization approaches available to prevent economically devastating swine diseases and spillover events between pigs and humans. PigMatrix and EpiCC are two new tools for swine T cell epitope identification and vaccine efficacy analysis that have been integrated into an existing computational vaccine design platform named iVAX. The iVAX platform is already in use for the development of human vaccines, thus integration of these tools into iVAX improves and expands the utility of the platform overall by making previously validated immunoinforma...

Quantifying soil N < sub > 2 < /sub > O emissions from soil and anaerobically digested swine manure, nitrification and denitrification using < sup > 15 < /sup > N isotope labeling method
Environ Sci Pollut Res Int. 2021 Feb 23. doi: 10.1007/s11356-021-12981-z. Online ahead of print.ABSTRACTIncreasing use of anaerobically digested swine manure in the farmland makes it necessary to understand its impact on N2O emissions, regarding the source of N2O and the corresponding mechanism of action. We used a 15N-labeled sulfate modifying the soil in order to identify the sources of N2O and the pathways of nitrification and denitrification. Three soil moisture contents (50% WHC, 75% WHC, and 100% WHC) along with three levels of anaerobically digested swine manure (0 g·kg-1, 10 g·kg-1, and 25 g·kg-1) were tested us...

Pilot study on the effects of low intensity focused ultrasound in a swine model of neuropathic pain
CONCLUSIONS: The results demonstrate that a 5-cm depth can be reached with external liFUS and alters pain behavior and allodynia in a large-animal model of neuropathic pain.PMID:33862597 | DOI:10.3171/2020.9.JNS202962

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...

Variations of antibiotic resistome in swine wastewater during full-scale anaerobic digestion treatment
Environ Int. 2021 Jun 12;155:106694. doi: 10.1016/j.envint.2021.106694. Online ahead of print.ABSTRACTAnaerobic digesters have been widely used to treat wastewaters in livestock farms. With the increasing risk of antibiotic resistance originated from livestock husbandry, removal of antibiotics and antibiotic resistance genes (ARGs) via anaerobic digesters deserved more attention. Here we investigated the removal of antibiotics and ARGs in swine wastewater by three on-farm full-scale anaerobic digesters, including buried biogas digester (BBD), up-flow anaerobic sludge blanket (UASB) and high density polyethylene covered bio...
