Alterations in the gut resistomes of endangered wild equids associated with anthropogenic activities: Insights for One Health surveillance. Antibiotic resistance genes (ARGs) are emerging environmental contaminants, but how human-associated management practices are associated with mobile resistomes in endangered wildlife remains poorly resolved. Here, we used fecal metagenomics to compare Przewalski's horses, Mongolian khulans, and domestic horses from Xinjiang, China, including Przewalski's horses from a protected area and a captive-breeding setting under human management. Across 47 fecal metagenomes, we identified 380 ARG subtypes, 23 metal resistance gene (MRG) types, and 26 mobile genetic element (MGE) subtypes. Przewalski's h...
Structural and functional analysis of the inhibition of equine glutathione transferase A3-3 by organotin endocrine disrupting pollutants. Organotin compounds are highly toxic environmental pollutants with neurotoxic and endocrine-disrupting effects. They are potent inhibitors of glutathione transferases (GSTs), thus impeding their detoxication and antioxidant functions. Several GSTs, including equine GST A3-3 (EcaGST A3-3), exhibit steroid double-bond isomerase activity and are involved in the biosynthesis of testosterone and progesterone. We have performed enzyme kinetics analyses of the inhibition of EcaGST A3-3 by organotin compounds. We have also solved crystal structures of EcaGST A3-3 in complexes with glutathione, and wit...
Chloride/bromide ratios in leachate derived from farm-animal waste. Ratios of conservative chemicals have been used to identify sources of groundwater contamination. While chloride/bromide ratios have been reported for several common sources of groundwater contamination, little work has been done on leachate derived from farm-animal waste. In this study, chloride/bromide ratios were measured in leachate derived from longhorn-cattle, quarterhorse, and pygme-goat waste at a farm in Abilene, Texas, USA. (Minimum, median, and maximum) chloride/bromide ratios of (66.5, 85.6, and 167), (119, 146, and 156), and (35.4, 57.8, and 165) were observed for cattle, horses, ...
