👉 Phagedenical is a term used in microbiology and biochemistry to describe a bacterium that has been genetically engineered to produce a specific antibiotic or other therapeutic agent. The bacteria are engineered to be resistant to antibiotics, which can be useful for treating infections caused by resistant bacteria. Phagedenicals have been developed through genetic engineering techniques, such as CRISPR-Cas9, and are often used in the treatment of bacterial diseases.
