Broad microbial proteins and membranes

Broad microbial proteins and membranes encompass the collective structural and functional elements of microorganisms, including the lipid bilayer and various cytoplasmic proteins, which are essential for cellular integrity and metabolism (McDonnell & Russell, 1999). These components serve as the primary targets for non-specific antimicrobial agents such as antiseptics and disinfectants (CDC, 2008). The mechanism of action for these agents typically involves the denaturation of proteins, disruption of the cell membrane, or oxidation of cellular constituents, leading to rapid microbial death (StatPearls, 2023). Because these agents target fundamental biological structures common to many life forms, they often lack the high selectivity seen in systemic antibiotics, which can lead to host tissue irritation or toxicity (NIH, 2022). This broad-spectrum activity is crucial for effective sterilization and disinfection in clinical environments to prevent the spread of infections (WHO, 2009). However, the therapeutic use of such agents is generally limited to topical applications or inanimate surfaces due to their potential for damaging human cells (PubMed, 2021).
