“…In contrast, most agricultural and environmental bacteria are not pathogens, the term “resistant” can be applied either to an isolate, or to a whole community of bacteria, and the threat to health is indirect (Williams-Nguyen et al 2016). There is no consensus or standardized methods for defining or determining AR in non-clinical settings (Berendonk et al 2015; McLain et al 2016; Durso and Schmidt 2018), and the detection of any part of any target gene or determinant DNA sequence results in the sample being described as “resistant.” Where possible, researchers use clinical standards, but the relevance of those methods and links to risk (i.e., disease outcomes) are not known for most environmental bacteria (Williams-Nguyen et al 2016; McLain et al 2016). Though cumbersome, the use of qualifiers such as “clinical resistance” or “environmental resistance” would provide vocabulary to distinguish the two concepts when working in a One Health setting.…”

Agriculture reflects One Health principals, with the job of the farmer being to sustainably balance human, animal, and soil health. It is imperative to include an agricultural perspective when addressing antibiotic resistance (AR) from a One Health perspective, as the farmers, ranchers, and agricultural professionals have an intimate working knowledge of these complex systems, and they will be on the front lines of implementing on-farm control measures. Currently, communication across the One Health triad (humans, animals, environment) regarding agricultural AR is hindered by ambiguous language, complicated by cultural and linguistic differences that can lead to the conclusion that the other participant is not aware of the facts, or has ulterior motives. This work explores and identifies the language and vocabulary of AR in the context of supporting strategic short-and long-term problem solving in a One Health context.

“…In addition to the impact of agricultural runoff on microbial water quality, there is increasing attention being paid to the role of runoff as a potential mechanism for the transport of agriculturally‐associated antibiotic‐resistant bacteria (ARB) and antibiotic resistance genes (ARG) out of agricultural systems via surface or ground waters (Durso & Millmier Schmidt, 2018; Durso et al., 2018). We collected E .…”

Although the land application of livestock manure has numerous agronomic benefits, runoff from manured fields can degrade water quality. Setbacks instruct a minimum distance be maintained between manure application and surface waters. They are commonly used to manage nutrient contamination of surface waters; however, their utility for reducing microbial inputs remains unclear. Here we evaluated the efficacy of five setback distances in no-till wheat (Triticum aestivum L.) residue plots for reducing runoff fecal indicator concentrations from swine manure-amended fields. Also, since there is increasing interest in the use of water quality indicators to monitor antibiotic resistance in environmental systems, Escherichia coli and Enterococcus isolates were collected, and evaluated for resistance to 12 antibiotics. Seven of the 12 antibiotics evaluated in this study are critically important to human health and another four of the antibiotics evaluated are highly important to human health, according to World Health Organization (WHO) guidelines. Significant differences existed in amounts of indicators from pre-and post-manure application time points; however, no significant differences were observed for any of the five setback distances measured (range 4.9-23.2 m). Antibiotic-resistant E. coli and Enterococcus were isolated from pre-and post-application runoff, indicating presence of antibiotic-resistant fecal indicators in both manured and in non-manured soils, although the source manure had a higher percentage of isolates displaying resistance. It remains difficult to provide recommendations for concurrent reduction of nutrient and microbial contaminants.

“…However, dwindling non‐renewable resources and increasing fertilizer production costs are driving interest in innovative fertilizer use, including interest in manure‐based fertilizers such as PL. Animal manure is beneficial for nutrient recycling (Schröder et al., 2020), but it also comes with its own set of challenges, inherent to all fecal materials (Broszat & Grohmann, 2017; Durso & Schmidt, 2017). While both mineral and manure‐based fertilizers change the microbial communities of soil, animal manure contains a high concentration of enteric bacteria, including antibiotic resistant (AR) bacteria and potential pathogens (Hubbard et al., 2020).…”

Given the high cost and non‐renewability of mineral‐based fertilizers, there is increasing interest in the innovative use of manure‐based materials, such as poultry litter (PL). However, manure‐based fertilizers add both nutrients and microbes to the soil, including antibiotic‐resistant Escherichia coli (AREc). PL soil amendment impact on AREc in corn fields was evaluated in a randomized field experiment (May–October 2017). Two winter cropping systems (fallow and cover crop) were assigned to whole plots, with three spring‐applied fertilizer treatments (untreated control [UC], PL, and commercial fertilizer [CF]) assigned to subplots. Soil was collected from 0 to 15 cm on days 0, 7, 28, 70, 98, and 172 post‐treatment applications. Samples were cultured for the enumeration and prevalence of generic, tetracycline‐resistant (TETr), third‐generation cephalosporin‐resistant (3GCr) E. coli isolates, and extended spectrum beta‐lactamase (ESBL)‐producing Enterobacteriaceae. PL soil amendment significantly (p < 0.05) increased the levels of generic E. coli, TETr E. coli, and 3GCr E. coli on days 7 and 28 compared to UC or CF. Beyond day 28, AREc did not significantly (p > 0.05) differ by fertilizer treatment and returned to baseline on day 70. ESBL‐producing Enterobacteriaceae were detected from 16 samples, mostly on day 70. Cover crop significantly decreased TETr E. coli concentration on day 28, with no significant effects on the prevalence of 3GCr E. coli and ESBL‐producing Enterobacteriaceae compared to no cover crop. All ESBL‐producing Enterobacteriaceae and 79% of the 3GCr E. coli isolates were positive for blaCTX‐M gene by polymerase chain reaction. Results show that PL soil amendment transiently increases the levels of AREc compared to mineral fertilizer.
