The Looming Threat of Antimicrobial Resistance (AMR)

• Pathogens are not constrained by borders, and antimicrobial resistance (AMR) is a growing global threat.
• Studies suggest AMR could kill 10 million people annually by 2050.
• The video explores the potential of bacteriophages (phages) as an alternative treatment to combat AMR.

Bacteriophages: Nature's Bacterial Killers

• Bacteriophages (phages) are viruses that infect and kill bacteria. They are harmless to humans.
• Phages inject their genetic material into specific bacteria, using them as hosts to replicate.
• They rapidly multiply and force the bacteria to explode, maintaining the biological balance of the planet.
• For every bacteria, there is a bacteriophage that can kill it.

Phage Research and Sample Collection

• Researchers collect samples from various environments, including sewage, to isolate phages.
• Ben Chan, an American researcher, collects samples from Kibera, one of the largest slums in Africa, where sanitation issues contribute to the spread of bacteria.
• He emphasizes the importance of being interested in "sewage and gross stuff" to find phages that can kill disease-causing bacteria.
• He notes that he has never found the same phage twice, highlighting the diversity and potential of phage therapy.

Phage Therapy: A Potential Solution

• Phage therapy has the potential to revolutionize the treatment of infections and the production of pharmaceuticals.
• Phages are open for anyone to use due to the lack of intellectual property.
• Phages could be produced for a fraction of a penny per dose, making them a low-cost alternative to antibiotics.
• Dedicated labs worldwide could create phage products, reducing dependence on large pharmaceutical companies.

Challenges and Opportunities in Developing Countries

• Tobi Nagel, founder of Phages for Global Health, aims to reverse the trend of developing countries receiving drugs after industrialized nations.
• She advocates for local drug development using phages.
• Researchers in Africa face challenges such as high costs of reagents and supplies. Syringe filters can cost tenfold more than in the US.
• Despite these challenges, African research institutes like KEMRI have isolated hundreds of phages.

Global Collaboration and Phage Banks

• International collaborations are crucial for developing phage therapy solutions.
• KEMRI sends phages to the Walter Reed Army Institute of Research in the US for storage and study.
• Mikeljon Nikolich at Walter Reed emphasizes the need for a diversity of phages to develop off-the-shelf antimicrobial products.
• The Eliava Institute in Tbilisi, Georgia, is a global leader in phage therapy, with over a century of experience and a stock of over a thousand phages.
• The institute provides customized phage treatments starting at around 4,000 euros.

Phage Therapy in the United States

• Adaptive Phage Therapeutics (APT) in Gaithersburg, Maryland, obtains phages from the Walter Reed Army Institute.
• APT uses an automated process to preselect suitable phages and has a patented database of phages licensed to therapy centers across the US.
• APT estimates the cost per phage therapy to be around 20,000 U.S. dollars.
• Phage therapy is not currently approved by the FDA, but APT receives one to two requests daily for emergency or compassionate use.

Compassionate Use at Yale University

• Ben Chan is the scientific director at the Center for Phage Biology and Therapy at Yale University.
• Yale is one of a handful of established phage therapy centers in the world.
• They use phages in clinical trials for "compassionate treatment" in cases of extreme infection and antimicrobial resistance where other therapies have failed.
• They have had solid success, nearly 100%, treating prosthetic joint infections.
• They are also testing bacteriophage therapy in people that have cystic fibrosis.

Case Study: Maggie Donovan and Cystic Fibrosis

• Maggie Donovan, a cystic fibrosis patient infected with the MRSA superbug, received supplemental phage therapy at Yale.
• The phage destroyed the superbug enough that it can now respond to antibiotics.
• After a series of therapy sessions, Maggie's symptoms improved significantly, leading to a better quality of life.

Phage Research in Uganda

• Jesca Nakavuma is Uganda's leading phage expert and the founder of the Phage Team Uganda at Makerere University.
• The team is fighting drug-resistant bacteria in humans, animals, and food production.
• Professor Ritah Nakayinga and her colleagues are hunting for phages at a sewage plant in Kampala to combat bacteria that infect bananas, a staple food crop.
• They are seeking a "superhero" phage that can kill as many strains as possible.
• Makerere University is a pioneer in phage bank development, but frequent power outages pose a threat to the project.

Phage Therapy in Animal Husbandry

• The International Livestock Research Institute in Nairobi is conducting clinical trials using phage therapy for salmonella infections in poultry.
• Angela Makumi and her team have an international partnership with Laval University in Canada.
• A Canadian biotech company uses phage cocktails from Kenya and dehydrates them into a concentrated powder for use in animal feed.
• 85% of the antibiotics produced worldwide are used in the livestock industry.
• The EU banned routine use and restricted the preventive use of antibiotics on healthy livestock in 2022.

Phage Applications in Food Safety

• Intralytix, a biotech company in the US, specializes in the development and production of bacteriophage products for food safety.
• They focus on food-borne pathogens like listeria, salmonella, and E.coli bacteria.
• They were the first company in the world to receive FDA approval for food safety products.
• Some producers with official approval to use phages prefer to remain anonymous due to fear of public backlash.

Phage Therapy in Aquaculture

• Fish farmer Thomas Missisoke in Uganda is a partner in a research project using phage therapy for salmonella infections in fish.
• He is committed to safe fish farming practices and avoids using chicken waste, which can contain harmful residues of medicine.

Phage Therapy for Wildlife Conservation

• Antimicrobial-resistant bacteria are a threat to gorillas in Bwindi Impenetrable Forest National Park in Uganda.
• Nelson Bukamba, a field veterinarian, is researching phage therapy to help protect the gorillas.
• Visitors to the park can unwittingly transport dangerous pathogens, posing a major threat to the animals.
• Gorillas and humans share about 98 percent of the same DNA, making them susceptible to human diseases.

The Future of Phage Therapy

• A symposium on phage research is held at the Institute of Primate Research in Kenya.
• Researchers hope that KEMRI will have a national phage bank for quick deployment in outbreaks.
• The Kenyan authorities have approved adding phages to the water supply in Kilifi to prevent outbreaks of bacterial infections.
• Researchers are optimistic about the potential of phage therapy to combat AMR and improve global health.

Conclusion

The video highlights the urgent need to address antimicrobial resistance and explores the potential of phage therapy as a promising alternative treatment. It showcases research efforts and collaborations across the globe, from Africa to the United States, and emphasizes the importance of developing phage banks, promoting local drug development, and implementing phage therapy in various sectors, including human health, animal husbandry, food safety, and wildlife conservation. While challenges remain, the video conveys a sense of optimism and determination to harness the power of phages to combat AMR and improve global health outcomes.
