Several members from the team will be presenting at the conference. Dr. Pruden will be giving a talk as an overview of the research findings to date; Dr. Partha Ray will present a poster on the excretion of antibiotics; Lauren Wind will present on the field study; and Giselle Guron, Carmen Wickware, and Emily Garner will be presenting on the composting study. Chrissy Teets and Ellen Russell will be attending. Additionally, our team will be having an informal dinner with several of our advisory board members, who will be attending the conference: Ed Topp, Jean McLain, Lisa Durso, and Heather Allen.

Several member of our team presented at the IAFP 2017 Annual Meeting held in Tampa, FL: Vaishali Dharmarha presented “Storage Temperature and Sanitizer Washing Influences the Bacterial Community Dynamics of Carrots” and “An Assessment of Produce Growers’ Sanitizer Practices and Knowledge about Antimicrobial Resistance”; Kendall Fogler presented “Microbial Community Analysis of Field Grown Produce in Soil Amended with Manure or Compost from Antibiotic Treated Cattle”; and Giselle Guron presented “Metagenomic Analysis of Antibiotic Resistance Genes and Mobile Genetic Elements Found on Radish Taproots Grown in Soils Amended with Manure and Compost from Cattle” and “Quantifying Sulfonamide Resistance Genes on Lettuce Grown in Soil Amended with Manure and Compost from Antibiotic-Treated Cattle”.

Two of our graduate students presented results from our field study at the conference held in Athens, GA. Lauren Wind presented “Persistence of culturable antibiotic resistant fecal coliforms from manure-amended vegetable fields”, and Kyle Jacobs presented “Indicator bacteria, sediment, and antibiotic-resistance gene transport via runoff from vegetable plots amended with manure”.

Hanh Le, a student of Dr. Xia, recently attended the American Society of Agronomy (ASA), Crop Science Society of America (CSSA), and Soil Science Society of America (SSSA) 2016 International Annual Meeting in Phoenix, Arizona. She gave a presentation entitled “Effects of Manure Land Application Technologies and Timing on Environmental Fate of Four Antibiotics Commonly Used in Dairy Production”. Her presentation was awarded 2nd place for best student oral presentation award of SSSA Soils and Environmental Quality Division. Congratulations, Hanh!

Amy Pruden participated in the Water Reuse Symposium, participating in a panel discussion on the topic of Water Reclamation and Antibiotic Resistance: Where are we now?. The conference took place September 11-14 in Tampa FL.

Amy Pruden delivered a keynote lecture at the International Water Association Microbial Ecology and Water Engineering Conference. She discussed the microbial ecological processes that may either enhance or reduce the spread of antibiotic resistance genes during waste management, water treatment, and distribution. Antimicrobial Resistance in Wastewater Treatment Plants: A Call to Action. International Water Association Specialty Group on Microbial Ecology and Water Engineering. Sept. 4-6, Copenhagen, Denmark (2016- forthcoming).

Post-doctoral researcher Chaoqi Chen traveled to Philadelphia, PA, to present “Fate and Transformation of Veterinary Antibiotics in Soils”.

Several project team members attended the 2016 IAFP Annual Meeting in St. Louis, Missouri. Giselle Guron (below) presented her poster, titled, “Assessing the potential for antibiotic resistant bacteria to carry over from soil amendments to vegetable surfaces.

Christine Pankow presented her poster on the fate of antibiotic resistant bacteria in soil following manure versus compost application.
 
 
 
Robert K. Williams presented his poster on the effect of composting method and antibiotic residue in manure on the fate of E. coli and antibiotic resistant genes in cattle manures.

Amy Pruden delivered an invited keynote lecture at the International Water Association Leading-Edge Technology Conference in Jerez, Spain. The aim was to discuss how treatment and reuse of domestic wastewater can be conceptualized in a way to reduce the spread of antibiotic resistance, for examples, as a source of irrigation water: “Synergizing Water Sustainability and Public Health: Antibiotic Resistance and Opportunistic Pathogens in Recycled Water. International Water Association Leading Edge Technology Conference (LET 2016), June, Jerez de la Frontera, Spain (June 13-16, 2016).
