Protecting Bacteriophages with a Mathematical Model

Topic: Health

Researchers from Spain created a mathematical model to help protect bacteriophages without reducing their ability to fight bacteria. This breakthrough could lead to more effective treatments for antibiotic-resistant infections.

Scientists at the Autonomous University of Barcelona have developed a mathematical model that helps protect bacteriophages, viruses that can destroy bacteria, as they travel through the digestive system.

Bacteriophages are considered one of the most promising alternatives to antibiotics in fighting antimicrobial resistance. However, when given orally, they face many challenges, including being degraded by stomach acids before reaching their destination. To overcome this, researchers have developed encapsulation systems that protect the viruses but also limit their ability to infect bacteria.

The new mathematical model, created by Sílvia Cuadrado and her team, describes how encapsulated bacteriophages behave in the gastrointestinal tract. It helps answer questions about how many viruses reach their destination, what characteristics the microcapsules should have, and how often they should be administered to maximize treatment effectiveness.

The study's key contribution is incorporating the encapsulation process into a mathematical model of bacteriophage therapy, an area that had previously received little attention. The model also distinguishes between the administered dose and the effective dose, which is the actual number of viruses available to combat infection.
