Phage therapy consists of using bacteriophage viruses,
also known as phages, to treat
specific bacterial infections.

Benefits of phages

  • Phages are found in nature. It is estimated that there are 1030 phages with 108 different genomes on the planet, providing an almost unlimited reservoir of therapeutic antibacterial agents to pick from.
  • Phages precisely target an infection. They only damage the bacterial cells they are supposed to kill.
  • Lytic phages kill bacteria that are resistant to antibiotics.
  • Phage therapy causes a lot less side effects than antibiotics.
  • Compared to antibiotics, that require long and expensive developments, using natural phages is rapid and inexpensive.

Antibiotic resistance in farm animals

Resistance occurs when a bacterium adapts and becomes resistant to the antibiotics used to treat the infections it causes.
We often talk about antibiotic resistance in humans, but much less in animals. The massive use of antibiotics in farm animals induces the development of antibiotic resistance to potentially fatal bacteria.
Researchers from the Swiss Federal Institute of Technology Zurich (ETH Zurich), the Princeton Environmental Institute (PEI) and the Free University of Brussels, found that between 2000 and 2018, the proportion of antibiotics showing resistance rates above 50% in developing countries had exploded: it went from 0.15 to 0.41 in chickens and from 0.13 to 0.34 in pigs.
“Multidrug resistant” bacteria are increasingly present, which can ultimately compromise the health of farm animals and of the people who consume these animals.
