Bacterial cell (non-specific oxidative interaction)

"Bacterial cells – non-specific oxidative interaction" refers to a broad-spectrum antimicrobial mechanism where oxidizing agents target multiple cellular components simultaneously rather than a single receptor or enzyme. These agents, including hydrogen peroxide and povidone-iodine, generate reactive oxygen species (ROS) or directly oxidize functional groups such as thiols in proteins and double bonds in lipids (McDonnell & Russell, 1999, Clinical Microbiology Reviews). This non-specific attack leads to the denaturation of essential enzymes, disruption of the plasma membrane, and fragmentation of bacterial DNA, resulting in rapid cell death (Finnegan et al., 2010, Journal of Antimicrobial Chemotherapy). This mechanism is highly effective against a wide range of pathogens, including Gram-positive and Gram-negative bacteria, and is less prone to the development of resistance due to its multi-target nature. It is the primary mode of action for many clinical antiseptics and disinfectants used to treat or prevent infections (StatPearls, Povidone-Iodine). However, because the interaction is non-selective, these agents can also damage host tissues, potentially causing irritation or impaired wound healing if used at high concentrations (Drosou et al., 2003, Wounds).
