Deep dives
Improper Prescription and Use in Healthcare Settings
Improper prescription and use of antibiotics in healthcare settings have contributed to the rise of antibiotic resistance. Antibiotics were initially used indiscriminately, even for viral infections, leading to the development of resistance. Overprescription and improper use of antibiotics in hospitals and clinics have also contributed to the spread of resistance. Additionally, improper use of antibiotics by patients, such as not completing the recommended course, has further fueled the problem. Proper regulation and education about the appropriate use of antibiotics are needed to address this issue.
Improper Use in Agriculture
The use of antibiotics in agriculture has also played a significant role in the rise of antibiotic resistance. Antibiotics were initially used as growth promoters in livestock, leading to faster growth rates. However, this practice created a breeding ground for resistance. Improper use included adding antibiotics to animal feed, injecting them into animals, and even using antibiotics for washing fruits and vegetables. This widespread use of antibiotics in agriculture contributed to the rapid spread of resistance in bacteria, which could transfer to humans through consumption of contaminated food or contact with animals.
Failure to Regulate and Address the Issue
Despite early warnings about the potential dangers of antibiotic resistance, regulations and actions to address the issue were often inadequate. In some cases, political and economic pressures undermined efforts to regulate the use of antibiotics. Resistance emerged rapidly, leading antibiotics to become less effective over time. This failure to effectively regulate and address the issue has contributed to the current state of antibiotic resistance, where many antibiotics have become ineffective against bacterial infections.
Importance of Proper Antibiotic Use
Proper antibiotic use is essential to combat antibiotic resistance. This includes appropriate prescription practices in healthcare settings, as well as responsible antibiotic use in agriculture. Regulation, education, and public awareness campaigns are crucial to promote the appropriate use of antibiotics and to slow down the spread of resistance. By understanding the root causes of antibiotic resistance and taking proactive measures, we can better protect the effectiveness of antibiotics and ensure their continued use in treating bacterial infections.
The impact of antibiotic use in agriculture on antibiotic resistance
The podcast episode highlights the concerning results of a study, which found antibiotic resistance in the gut bacteria of farmers and their families, as well as in the chickens they raised. The use of antibiotics in animals has been shown to contribute to an increase in antibiotic resistance in humans. Despite evidence of the detrimental effects, the US has not banned the use of certain antibiotics as growth promoters in livestock. Denmark and the Netherlands have implemented stricter regulations, leading to a decline in antibiotic use on farms and a decrease in antibiotic-resistant bacteria in meat. However, in the US, antibiotic use in agriculture continues to increase, contributing to the global problem of antibiotic resistance.
The emergence and spread of antibiotic-resistant bacteria
The podcast discusses the rise of antibiotic-resistant infections, highlighting the cases of vancomycin-resistant enterococci (VRE) and vancomycin-resistant Staphylococcus aureus (VRSA). The overuse of antibiotics in agriculture, particularly as growth promoters, has played a significant role in the emergence and spread of antibiotic-resistant bacteria. The resistance genes were already present in animals raised for meat, and when antibiotics were used clinically, the resistance spread rapidly. Lobbyists have opposed regulations on antibiotic use in agriculture, downplaying the clinical importance of antibiotic-resistant infections. The spread of antibiotic-resistant bacteria from agricultural settings to hospitals and communities is a pressing concern.
The potential of phage therapy as an alternative treatment
The podcast explores the potential of phage therapy, which utilizes bacteriophages, viruses that specifically target and kill bacteria, as an alternative treatment for antibiotic-resistant infections. Phage therapy is being actively researched and shows promise in treating infections caused by pathogenic bacteria. Researchers have successfully treated patients using phage therapy, and clinical trials are underway. Genetically modified phages and phage cocktails are being developed, and the use of phages alongside antibiotics shows synergistic effects. Phage therapy could help address the antibiotic resistance crisis and reduce the reliance on antibiotics in the future.
No story of antibiotics would be complete without the rise of resistance. As promised in our last episode, this week we dive into what the WHO calls ‘one of the biggest threats to global health, food security, and development today’ - antibiotic resistance. In the decades since their development, misuse and overuse of antibiotics has led to many becoming all but useless, and our world seems on the verge of plunging into a post-antibiotic era. How does resistance work? Where did it come from? Why did it spread so far so rapidly? Is there any hope? In this episode, we answer all these questions and more. First, we explore the many ways bacteria evade the weaponry of antibiotic compounds. Then we trace the global spread of these resistant bugs by examining the major contributors to their misuse and overuse. And finally we assess the current global status of antibiotic resistant infections (spoiler: it’s very bad) and search for any good news (spoiler: there’s a lot!). To chat about one super cool and innovative alternative to antibiotics, we are joined by the amazing Dr. Steffanie Strathdee (Twitter: @chngin_the_wrld), Associate Dean of Global Health Sciences, Harold Simon Professor at the University of California San Diego School of Medicine and Co-Director at the Center for Innovative Phage Applications and Therapeutics. Dr. Strathdee provides a firsthand account of helping her husband, Dr. Tom Patterson, fight off a deadly superbug infection by calling on a long-forgotten method of treating bacterial infections: phage therapy.
