The book "Antibacterial Peptide Protocols" offers a comprehensive collection of methods for researching antibacterial peptides, which act as natural antibiotics of the host. These peptides play a crucial role in the body's defense mechanism against various infectious agents, including bacteria, fungi, parasites, and viruses. Given the growing threat of multidrug-resistant microbes and the limited availability of new antibiotics, research in this area is of great importance. The book is aimed at both experienced researchers and newcomers, providing reliable techniques and strategies that are essential for the development and application of antibacterial peptides in clinical practice. This publication is a valuable contribution to the growing field of antibacterial peptides and supports the scientific community in combating infectious diseases.
