4th Annual International Environmental Dimension of Antibiotic Resistance (EDAR) conference at Michigan State University

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.

International Association for Food Protection

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”.

NIFA Food Safety Project Directors Meeting

NIFA held the annual project directors’ meeting at the International Association for Food Protection (IAFP). Dr. Pruden attended the meeting in Tampa, FL, and presented a talk that provided an overview about our research and extension efforts.

American Ecological Engineering Society Meeting

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”.

Lauren Wind successfully defended her thesis

Lauren Wind successfully defended her thesis work entitled, “Persistence of Culturable Antibiotic Resistant Fecal Coliforms from Manure-Amended Vegetable Fields”. This thesis explores the effects of crop (lettuce, radish) and fertilizer type (inorganic, compost, raw manure) on the incidence and persistence of antibiotic-resistant fecal coliforms, a common family of fecal indicator bacteria used to track the environmental spread of antibiotic resistance.

Team Meeting

Project team monthly meeting in which the team is discussing research results shared by Christine Pankow.

Robert Williams successfully defended his thesis

Robert Williams successfully defended his thesis work entitled, “Effect of Composting on the Prevalence of Antibiotic Resistant Bacteria and Resistance Genes in Cattle Manure”. This thesis explores the effect of composting on the levels of ARGs and numbers of bacteria capable of growing on media containing antibiotics. Beef and dairy manure from cattle were studied and it was found that the composting process itself had a stronger influence than whether they had previously been administered antibiotics.
