Composting can reduce antimicrobial resistance in manure

A brief summary of the manuscript, Dissipation of Antimicrobial Resistance Determinants in Composted and Stockpiled Beef Cattle Manure by Xu et al. (2016)

Key Points:

  • Composting manure can reduce pathogen presence and antimicrobial residues in manure.
  • Composting efficacy in reducing antimicrobial residues in manure is associated with elevated temperatures within the composting process.
  • Stockpiling manure marginally reduce pathogen presence and antimicrobial residues in manure when compared to composting.

Application of organic fertilizers increases antibiotics in soil

A brief summary of the manuscript, Use of commercial organic fertilizer increases the abundance of antibiotic resistance genes and antibiotics in soil by Zhou et al. (2016)

Key Points:

  • Residual antibiotics can persist in soil for months following the application of manure-based, commercial organic fertilizers.
  • Antimicrobial resistance and antibiotic residues decreased significantly over the first 60 days following fertilizer application but did not return to background levels until four months after application.

Antibiotic resistance higher in environments impacted by human or animal waste.

A brief summary of the manuscript, Antimicrobial-resistant bacterial populations and antimicrobial resistance genes obtained from environments impacted by livestock and municipal waste (Agga et al., 2015)

Key Points

  • Antibiotic resistance is naturally occurring in almost any environment, making it difficult to determine what is the true human health risk associated with any change in environmental bacterial populations or genes.
  • This study found higher concentrations of resistant bacteria in both treated municipal wastewater and livestock wastes than are naturally present in soil or water.
  • Municipal wastewater samples contained a wider variety of antibiotic-resistant genes than were present in livestock wastes.

Communicating Science Using the Science of Communication

In the digital world in which we live today the public is presented with an overwhelming quantity of information, much of which is unscientific. In this webinar we will apply the lessons learned from antimicrobial resistance and health communications to more science communication challenges. This presentation was originally broadcast on August 14, 2020. More… Continue reading “Communicating Science Using the Science of Communication”

How do you like your steak?

People worry, and I am no exception. I spend more time than I would like to admit on social media, and I have seen some things, disturbing things, things that cannot be unseen. Turns out there is a lot out there to be worried about; so how do I know I am worried the right amount and not too much? For example, I know that antimicrobial resistance (AMR) is a serious and growing health problem, but what does that mean for me? I want to know which aspects of the AMR crisis are going to impact me, which I do not have to worry about, and what I or others can do about it. The first thing I want to know more about is meat safety. I have seen the labels about “antibiotic-free meat”, and I want to know – how safe is my burger? So, I got in contact with some folks who really know meat to find out. Continue reading “How do you like your steak?”

Antimicrobial Resistance Resource Library

Antimicrobial-resistant (AMR) infections are a serious threat to global public health. Each year AMR accounts for roughly 700,000 deaths worldwide. While AMR-related research is ongoing, conveying research-based knowledge about AMR mechanisms, risks, and opportunities to improve outcomes to the general public, agricultural producers, food safety experts, educators, and consumers is imperative.

The iAMResponsible Project team, a nationwide extension effort for addressing AMR, has developed a shared resource library to curate and translate the latest news and research findings on AMR for a non-technical audience. This library is designed to provide educators and advisors with access to resources that will assist you in your discussion of antimicrobial resistance.  Please feel free to share and re-purpose educational products in this library with local audiences.

Are there alternatives to antibiotics?

A brief summary of the manuscript, Alternatives to Antibiotics: Why and How (Allen, 2017), a review of current and potential alternatives to antibiotics for use in human or veterinary medicine.

Key Takeaways:

  • Every time antibiotics are used, impacted bacteria adapt to survive. Bacteria that are not killed by the antibiotic pass on their new survival traits to later generations of bacteria, which limit the effect of the antibiotic the next time it is used.
  • Antibiotics are not the only way to treat bacterial diseases. Alternative treatment methods to consider include vaccines, immunotherapeutics, bacteriophage therapy, and probiotics.

Antimicrobial Resistance in Developing Countries: Current State and Controlling Strategies

In most developing countries, access to antimicrobial drugs is as easy as a run to the grocery store or nearby pharmacy – with or without a prescription from a medical professional. Even with a prescription, patients may not complete their doses, or they may not fully recover from an infection that then continues after the duration of the medicine. How does this unregulated use of antibiotics and related medications relate to the development and spread of antimicrobial resistance in developing countries and what strategies may help mitigate this increasing health crisis? Continue reading “Antimicrobial Resistance in Developing Countries: Current State and Controlling Strategies”

Antimicrobial Resistance is Native to the Environment

Germs are everywhere, some resistant to medical treatment

When I was a kid, I remember being called inside for lunch on a summer day and hearing, “Wash your hands! You’ve been playing in the dirt!” Of course, we all grew up knowing that dirty hands can spread germs. But, I didn’t know until I was much older that the same soil that made my hands dirty was also the source of some pretty amazing medicines.
