Scientists have taught artificial intelligence to design entire bacteriophage genomes. Sixteen phages created this way were viable and capable of destroying Escherichia coli. Some of them outperformed the natural phage on which they were based.
In the journal Nature Biotechnology, scientists presented a new tool, PALACE, that helps discover previously unknown bacteriophages. The algorithm analyzes massive amounts of genetic data and reconstructs complete phage genomes much more accurately than existing methods. This means researchers will be able to discover new bacteriophages more quickly and better understand their properties.
In July 2026, a clinical case of a 40-year-old patient with severe lung infections caused by three multidrug-resistant bacteria— Acinetobacter baumannii, Klebsiella pneumoniae, and Stenotrophomonas malto—was published in the journal Nature Communications. Previous antibiotic treatment had failed to fully control the infection, so doctors decided to use personalized phage therapy.

In 2026, a clinical case of a patient with a severe vascular graft infection caused by Pseudomonas aeruginosa was published in the journal Nature Communications. The bacteria formed a biofilm and proved resistant to multiple antibiotics. Doctors selected a customized combination of bacteriophages and antibiotics for the patient, having previously tested their effectiveness in the laboratory. After treatment, signs of inflammation around the graft significantly decreased, and the patient experienced no further episodes of bacteremia for a year.
When we talk about bacteriophages, we usually think of their use in combating antibiotic-resistant bacteria in medicine. However, a new scientific review has shown that these natural bacteria hunters can also protect agricultural crops. Bacteriophages can selectively destroy bacteria that cause dangerous diseases in tomatoes, potatoes, apples, pears, peppers, and other plants without harming the plants themselves, humans, or beneficial microorganisms.
In a new study, scientists described a unique case of treating a patient with cystic fibrosis whose chronic lung infection was caused by the bacterium Pseudomonas aeruginosa. When standard antibiotics failed, doctors used combination therapy—antibiotics combined with bacteriophages. A most interesting development occurred during treatment: the bacteria diverged into different groups with different survival strategies. Some became more vulnerable to antibiotics, others to phages.

Bacteriophages can combat more than just infections. In a new 2026 study, scientists used phages against a specific strain of Klebsiella pneumoniae, which is associated with the development of autoimmune inflammation. After eliminating these bacteria, symptoms of the disease significantly decreased. This opens the prospect of using phage therapy not only as an alternative to antibiotics but also as a tool for precisely targeting the human microbiome and immune system.

Bacteriophages can interact with a much wider range of bacteria than previously thought. Researchers from Rice University have developed a new RNA barcoding method that allows them to literally "label" bacteria that have received genetic material from phages and track these processes directly in natural microbial communities.

Modern medicine is increasingly moving toward individualized treatment. New research shows that the success of phage therapy depends not only on the correct selection of bacteriophage, but also on the patient's immune system and the genetic diversity of the bacteria.

Bacterial viruses alleviated the symptoms of E. coli poisoning in mice and rabbits, despite antibiotic treatment often worsening the condition. This result was achieved by inserting the CRISPR-Cas12 tool into the viruses, which cut out the region of the genome responsible for toxin production. Although this approach still requires human trials and the determination of a safe dose, it could become a targeted method for combating various antibiotic-resistant bacteria, not just E. coli.

The article discusses the rapid rise of antibiotic resistance—a situation where bacteria stop responding even to strong antibiotics—and explains why Ukraine has become one of the most problematic countries in Europe in this regard. It also discusses the causes of this crisis, the impact of the war on the spread of resistant infections, and the steps the government has begun to implement to combat the problem.

The world is approaching a dangerous point where antibiotics no longer work. Bacteria are rapidly developing drug resistance, and some infections are already nearly impossible to treat with conventional medications. People who have undergone transplants, cancer patients, cystic fibrosis patients, or those with weakened immune systems are particularly vulnerable. Even routine surgeries, once considered routine, can now be accompanied by dangerous bacterial complications. Against this backdrop, scientists are increasingly turning their attention to phage therapy—treatment using bacteriophages.

A new study on Mycobacterium abscessus has revealed an important detail: bacteria can "escape" even bacteriophages—the viruses that destroy them. In response to phage therapy, they change their shape or mutate, making treatment less effective. This is especially relevant against the backdrop of rising antimicrobial resistance, when conventional antibiotics are increasingly ineffective. But there's good news: scientists have found a solution—combination phage therapy—that simultaneously targets different bacterial variants.

Bacterial viruses have proven capable of reading chemical signals from other species indicating how many bacteria are still available for capture, and using this information to decide whether to enter dormancy or actively replicate. However, this "eavesdropping" is only useful for the viruses that produce these chemical signals themselves, not for those that read them. Since bacterial viruses are being explored as a means of combating antibiotic-resistant infections, the ability to influence the behavior of these viruses will improve the effectiveness of such measures.

Today, phage therapy is no longer just an alternative to antibiotics, but a new approach to fighting infections. It combines biology, genetics, and modern technology, opening the door to treatments that until recently seemed impossible. If this field continues to develop, humanity may have a powerful answer to the challenge posed by the era of antibiotic resistance.
Scientists describe a new mechanism that demonstrates the complexity of the "battle" between viruses and bacteria. The bacteriophage in question is HY126, which has a specialized enzyme system in its genome that modifies viral DNA. This mechanism involves two sequential chemical modifications of cytosine, one of the DNA bases: hydroxylation and the subsequent addition of arabinose molecules. This discovery expands our understanding of phage biology and reveals new ways in which viruses evade bacterial defenses.
A novel bacteriophage isolated from slaughterhouse wastewater and poultry farm effluent could be the key to protecting against Salmonella poisoning.
Sometimes a person’s legacy is not just their scientific achievements, but also the light they light in others. Professor Parviz Sabour was just such a person: an outstanding microbiologist, educator, and science communicator who dedicated his life to the study of bacteriophages and food safety. After his death, his family fulfilled his dream by establishing the Sabour Graduate Awards to support young scientists working in these important areas.
