A Mathematical Model for Antibiotic Resistance in a Hospital Setting with a Varying Population
<p>Antibiotic-resistant bacteria(ARB) is causing increased health risk and cost to society. Mathematical models have been developed to study the transmission of resistant bacteria and the efficacy of preventive measures to slow its spread within a hospital setting. The majority of these models have …

Shotgun metagenomic analysis of antimicrobial resistance in wastewater
… of living with the potential return to a pre-antibiotic condition where deadly infections are no longer treatable. Wastewater treatment plants (WWTPs) are vital components in water sanitation infrastructure and are now also being recognized as valuable monitoring points for antibiotics, …

Improved monitoring of emerging environmental biocontaminants through (nano)biosensors and molecular analyses
… One such shift is the advent of the modern antibiotic era, in which mass production and outputs of antibiotics, which are mostly naturally-derived microbial defense compounds and include a few synthetic antimicrobials, has profound implications for contributing to the spread of antibiotic …

Metagenomics-Based Environmental Monitoring of Antibiotic Resistance: Towards Standardization
Antibiotic resistance (AR) is a critical and looming threat to human health that requires action across the One Health continuum (humans, animals, environment). Coordinated surveillance within the environmental sector is largely underdeveloped in current National Action Plans to combat the spread …

Modeling Fecal Indicator Bacteria and Antibiotic Resistance in Diverse Aquatic Environments
… Understanding the sources of fecal indicator bacteria (FIB) and the environmental processes that affect them can be crucial to reducing the number of impaired streams and limiting the negative impacts on the environment. Antibiotic resistance is an emerging issue facing human health in the …

Antimicrobial resistance in soil: long-term effects on microbial communities, interactions with soil properties, and transport of antimicrobial elements
Since penicillin was discovered in 1928, antibiotic usage in human and veterinary medicine and prevalence of antibiotic resistant bacteria (ARB), has been increasing. While antibiotics and antibiotic resistance genes (ARGs) naturally occur in soils, increasing abundances of ARGs correlate with …

Evaluating and Improving Performance of Bisulfite Short Reads Alignment and the Identification of Differentially Methylated Sites
… conditions that affect proliferation of antibiotic resistance genes (ARGs), 2) identifying the effect of water chemistry and water age on microbial regrowth, and 3) characterizing co-occurrence of ARGs and/or mobile genetics elements (MGEs), i.e., plasmids in simulated RWDs. Analyses of …

Effect of Standard Post-harvest Interventions of Fresh Vegetables on Bacterial Community Dynamics, Pathogen Survival and Antibiotic Resistance
… is an established source of pathogenic bacterial contamination. However, less is known about whether such soil amendments could serve as a source of transmission of antibiotic-resistant bacteria (ARB) or antibiotic-resistance genes (ARGs) via fresh produce. As such knowledge is …

Characterizing the fate and transport of chemicals of emerging concern (CECs) from swine manure during waste to energy processes
… for biological processes that cultivated bacteria and algae to provide improved LPAM water quality and a bioenergy feedstock. The mixed algal-bacterial bioreactor (MABB) was operated with and without the addition of granular activated carbon (GAC) to enhance the removal of CECs and other …

Molecular detection, quantification and characterization of extended-spectrum β-lactamase (ESBL)- and AmpC-encoding genes in a cucumber agroecosystem
… and agricultural settings. The presence of antibiotic resistant bacteria (ARB) (including extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae) in fresh produce, is therefore imperative owing to the global push towards healthier diets with a focus on raw food due to its high …

Assessing Vulnerabilities to the Spread of Pathogens and Antibiotic Resistance in Agricultural and Water Systems Using Culture-, Molecular-, and Metagenomic-based Techniques
… that optimal treatment approaches reduce antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARGs). Key systems that were the focus of this effort included nutrient reuse (wastewater-derived biosolids and cattle-derived manure), water reuse, and drinking water systems …

Tracking Antibiotic Resistance throughout Agroecosystems
Widespread use of antibiotics in livestock production can result in the dissemination of bacteria carrying antibiotic resistance genes (ARGs) to the broader environment. Within agroecosystems, ARGs can pose a risk to livestock handlers, farmers, and ultimately consumers. The overall goals of this …

Impact of Manure Land Management Practices on Manure Borne Antibiotic Resistant Elements (AREs) in Agroecosystems
Rising global antibiotic resistance has caused concerns over sources and pathways for the spread of contributing factors. Majority of the antimicrobials used in the U.S. are involved in veterinary medicine, primarily with livestock rearing. Animal manure land application integrates livestock …

Persistence of Culturable Antibiotic Resistant Fecal Coliforms From Manure Amended Vegetable Fields
The reduced efficacy of antibiotics in treating common infections is one of the most pressing health concerns of the 21st Century. Increasing evidence links the widespread use of antibiotics in livestock production to the transfer of bacteria carrying antibiotic resistance genes to the broader …
