Effects of Insulin-degrading enzyme on the proliferation of swine Sertoli cells
Cell Mol Biol (Noisy-le-grand). 2023 Jan 31;69(1):13-18. doi: 10.14715/cmb/2022.69.1.3.ABSTRACTSertoli cells, the only somatic cells in testis seminiferous tubules, provide a supporting microenvironment for male germ cells and play essential roles in spermatogenesis. The insulin-degrading enzyme (IDE), a ubiquitous zinc peptidase of the inverzincin family, plays crucial role in sperm production, as IDE-knockout mice presented decreased testis weight and impaired sperm viability and morphology. However, whether and how IDE affects swine Sertoli cell proliferation remains unclear. Thus, in the present study, we aimed to eval...

Input and Leaching Potential of Copper, Zinc, and Selenium in Agricultural Soil from Swine Slurry.
Abstract
Trace elements, such as copper, zinc, and selenium, used as feed additives were determined in samples of both fresh (N = 14) and anaerobically digested (N = 6) swine slurry collected on medium- to large-size farms in northeast Spain. Considering both fresh and anaerobically digested samples, mean concentrations of zinc (1,500 mg kg(-1) dry mass [dm]) were greater than those of copper (mean 239 mg kg(-1 )dm), and the selenium concentrations detected were even lower (mean 139 μg kg(-1) dm). Zinc concentrations were significantly greater in anaerobically digested samples, whereas no significant d...

Methicillin-resistant Staphylococcus aureus in commercial swine herds is associated with disinfectant and zinc usage.
Abstract
Methicillin-resistant Staphylococcus aureus (MRSA) originating from swine is concerning for public health but an understanding of the emergence and persistence of MRSA in nursery herds is lacking. The aim of this study was to determine whether MRSA in nursery pigs is associated with particular herd-level parameters, including the use of antimicrobials, disinfectants, and heavy metals, which may be driving the selection and persistence of antimicrobial-resistance. Nasal cultures for MRSA were completed for 390 pigs from 26 farms at the end of the suckling phase and again at 3-weeks post-weaning. Herd-level...

Long-term effects of liquid swine manure land surface application in an apple orchard field on soil bacterial community and heavy metal contents in apple (Malus pumila Mill.)
This study investigated the impact of liquid swine manure (LSM) land surface application in an apple orchard on soil health and copper (Cu) and zinc (Zn) in soil and apple. Three apple plots were selected, among which two for LSM application for 5 (AY5) and 11 (AY11) years with different application rates, a long-term inorganic fertilizer application plot as the control treatment (AY0). The soil and apple samples were collected for analysis of soil physicochemical properties, bacterial diversity and abundance, and the contents of Cu and Zn in soil and apple. Results showed that the LSM application significantly increased t...

Bioremediation of zinc and manganese in swine wastewater by living microalgae: Performance, mechanism, and algal biomass utilization
Bioresour Technol. 2023 Jun 21:129382. doi: 10.1016/j.biortech.2023.129382. Online ahead of print.ABSTRACTThe remediation effects of living Chlorella sp. HL on zinc and manganese in swine wastewater was investigated, and the responses of algal cells and the mechanism were explored. In the wastewater with Zn(II) concentration of 1.85 mg/L and Mn(II) of 1 or 6 mg/L, the highest removal of Zn(II) by Chlorella reached 86.72% and 97.16%, respectively, and the Mn(II) removal were 42.74% and 30.33%, respectively. The antioxidant system of cells was activated by a significant increase in superoxide dismutase and catalase enzyme ac...

Quantification of airborne dust, endotoxins, human pathogens and antibiotic and metal resistance genes in Eastern Canadian swine confinement buildings
AbstractPig farming practices in Eastern Canada changed drastically into intensified and specialized operations. In large confined finishing facilities, workers are now exposed to concentrated biological particles (bioaerosols) for prolonged periods of time. Occupational exposure to airborne dust, endotoxins, bacteria, human pathogenic agents (Staphylococcus aureus, methicillin-resistantS.aureus,Salmonella spp.,Mycobacterium avium,Clostridium difficile andListeria monocytogenes), and antibiotic and metal resistance genes (cephalosporin, colistin, zinc) were investigated in 10 swine confinement buildings (SCBs). Average con...

Fate of antibiotic resistance genes and metal resistance genes during the thermophilic fermentation of solid and liquid swine manures in an ectopic fermentation system.
This study investigated the fate of antibiotic resistance genes (ARGs), metal resistance genes (MRGs), and class 1 integron-integrase gene (intI1) during thermophilic fermentation of swine manure in an ectopic fermentation system (EFS), which has been regarded as a novel system for efficiently treating both feces and urine. The abundances of MRGs and tetracycline resistance genes were 34.44-97.71% lower in the EFS. The supplementation of heavy metals significantly increased the abundance of intI1, with the enhancement effect of copper being more prominent than that of zinc. The highest abundances of resistance genes and in...

Understanding gaseous reduction in swine manure resulting from nanoparticle treatments under anaerobic storage conditions
In this study, two NPs: nano zinc oxide (nZnO) and nano silver (nAg) were tested in swine manure stored under anaerobic conditions to determine their effectiveness in mitigating gaseous emissions and total gas production. The biological sources of gas production, i.e., microbial populations were characterized via Quantitative Polymerase Chain Reaction (qPCR) analysis. Additionally, pH, redox, and VFAs were determined using standard methods. Each treatment of the experiment was replicated three times and NPs were applied at a dose of 3 g/L of manure. Also, headspace gas from all treatment replicates were analyzed for CH4 ...
