"Bacterial resistance" has become one of the greatest public health crises globally, posing a severe threat to the health of humans and animals. Various parties are actively seeking new solutions, and bacteriophages are expected to become one of the means to combat bacterial infections, potentially replacing or substituting antibiotics to some extent. However, the strong specificity of bacteriophages has, to some degree, limited their widespread application. We have established a rich library of pathogenic bacteria and bacteriophages and developed rapid and precise matching technologies for bacteriophages. This enables efficient and accurate enhancement of the match between bacteriophages and Klebsiella pneumoniae, significantly reducing workload and costs. We can quickly provide different phage cocktail formulations for human and animal Klebsiella pneumoniae infections, contributing to the reduction of antibiotic use, curbing bacterial resistance, and combating bacterial infections.
