Question

Quizplus · Accepted Answer

The mechanism of action behind the use of bacterial viruses (bacteriophages) to eliminate bacterial infections relies on the specificity of the viruses for their bacterial hosts. The attachment structures on the virus match with receptors on the bacterial cells, allowing the virus to infect and ultimately kill the bacteria. This specificity is what makes bacteriophage therapy a promising alternative to antibiotics, especially for treating antibiotic-resistant infections.
