The global increase in livestock production has correspondingly intensified farm odors due to harmful bacteria, reduced immunity, and disease progression. In this study, we treated feces with Biomagic-Enzyme complex for 4 months to understand the relationship between farm odor, immunity against common viral diseases, immune cytokines, and changes in the microbiota. A gas meter (MultiRAE) was used to measure ammonia (NH3) and hydrogen sulfide (H2S) while odor intensity and offensiveness were characterized by the non-objective scaling method. A complete blood count was performed and plasma was obtained after blood centrifugation at 3,000 rpm for 20 minutes. The cytokine profile was evaluated using commercial kits. Microbial DNA was extracted and purified from fecal samples to analyze the microbiota. Microbial DNA and viral RNA/DNA were obtained from fecal samples and amplified to determine the expression of transmissible gastroenteritis virus (TGEV), porcine reproductive and respiratory syndrome (PRRS), and porcine circovirus type 2 (PCV2). Our results indicated that Biomagic reduced odor nuisance by decreasing ammonia levels, resulting in faint and fairly offensive odor intensity. After the enzyme treatment, Escherichia coli populations significantly reduced across all 3 farms. In contrast, beneficial Lactobacillus spp. levels remained stable, indicating the enzyme selectively targeted harmful bacteria while preserving beneficial ones. The beneficial Lachnospiraceae, Spirochaetaceae, and Bacteroidaceae were found to be higher in the third month of treatment. TGEV was not detected, while PRRS and non-pathogenic PCV2 showed a positive infection rate. In conclusion, Biomagic reduced ammonia, prevented viral infection from pig farms, and improved gut-beneficial bacteria and microbiota.

Background:
Diabetic nephropathy (DN) is a progressive complication among patients with diabetes and the most common cause of end-stage kidney disease. Neutrophil extracellular traps (NETs) are known to play a role in kidney disease, thus this study aimed to determine their role in the development of diabetic kidney disease using diabetic murine models.
Results:
Protein and histological analyses revealed that db/db mice and streptozotocin DN models expressed no significant NET-related proteins, myeloperoxidase, citrullinated histone H3 (citH3), neutrophil elastase, and lymphocyte antigen 6 complex locus G6D (Ly6G). However, the inflamed individuals in the DN model showed that citH3 and Ly6G were highly deposited in the renal system based on immunohistochemistry images. In vitro, NET treatment did not induce apoptosis in glomerular endothelial and renal tubular epithelial cells. NET inhibition by DNase administration demonstrated no significant changes in cell apoptosis.
Conclusions
NET-related proteins were only expressed in the DN model with tubulointerstitial inflammation. Our study revealed that NETs are only induced in mice with hyperglycemia-induced inflammation.
