Bacteriophages

Bacteriophages have specialised over more than three billion years in infecting, killing and keeping bacteria under control. Some of these viruses kill so efficiently that they can be used purposefully instead of or in combination with antibiotics. Bacteriophages destroy bacteria without creating the same problems and side-effects as antibiotics. They could thereby become an effective, natural and environment-friendly alternative.

Bacteriophages have a number of applications in such areas as human and veterinary medicine, aquaculture, agriculture and food processing. They can become effective, natural and environment-friendly tools for combating antibiotic resistance in both people and animals.

The effect of bacteriophages against bacteria was described by French-Canadian microbiologist Félix D’Herelle in the 1920s. Experiments were conducted in subsequent years on using bacteriophages against infections.
Successful treatment with these viruses depends on knowing exactly which bacterial species are making the patient ill, so that the right bacteriophage can be deployed. This knowledge was not available in the 1920s and 1930s, and use of bacteriophages more or less ceased when Alexander Flemming discovered penicillin.
However, they continued to be used to treat infections in the Soviet Union and are still utilised today in such countries as Poland, Russia and Georgia when antibiotics prove ineffective against acne, sores, and skin, eye and gastrointestinal infections as well as against festering post-operative wounds in patients infected with antibiotic-resistant MRSA bacteria.

Post-1945 research on bacteriophages laid the basis for developing molecular biology and modern gene technology. With modern diagnostic methods and increased knowledge of pathogenic bacteria, a renewed commitment is being made to developing bacteriophages as one solution to the growing threat of antibiotic resistance.

Bacteriophages – a unique opportunity in the fight against antibiotic resistance

The report is a response to the challenge from Norwegian prime minister Erna Solberg. Many opportunities are available. Success can be achieved with commitment and right instruments.

Antibiotic resistance threatens the environment, animals, food production and public health

The threat posed by antibiotic resistance cannot be eliminated, but steps can be taken to reduce its progress.

Public health and modern medicine

Decades of medical research and progress could be reversed by antibiotic resistance.

Environmental consequences

The ecosystem in water, soil and organisms is disrupted by the production and use of pharmaceuticals and their subsequent disposal.

Antibiotics consumption in Norway

Norway is among the countries with the lowest consumption of antibiotics for both humans and animals, and has little problem with antibiotic resistance today.
