<p>Hemolysins are a varied group of bacterial toxins that play a significant role in making microbes more harmful by disrupting host cell membranes and affecting host-pathogen interactions. Both Gram-positive and Gram-negative bacteria produce hemolysins, which help them acquire nutrients, avoid the immune system, damage tissue, and spread. This review offers a detailed look at bacterial hemolysins, emphasizing their classification, structural differences, and how they work at a molecular level. It discusses the role of hemolysins in how microbes’ function and cause disease, as well as their interactions with host cell responses. The review summarizes current methods for detecting and characterizing hemolysins, highlighting progress in both analytical and molecular techniques. Furthermore, it examines recent advancements in targeting hemolysins through strategies that reduce their harmful effects and therapeutic inhibition. By connecting mechanisms with new intervention strategies, this review stresses the significance of hemolysins in microbial biology and their potential as targets for new antimicrobial methods.</p> Graphical abstract <p></p>
