Mechanisms of antibacterial action The classical approach to determining a mechanism of action relies upon establishing a correlation between concentrations initiating bacteriostatic or bactericidal effects and those precipitating specific biochemical or physiological changes (Bloomfield, 1991); where cor relation is seen a causal relationship is implied. Advantages & disadvantages: ... Phenol is no longer used as a disinfectant due to its toxicity and carcinogenicity. The impermeability and the presence of dipicolinic acid in bacterial spores make these forms much more resistant to disinfectants than vegetative forms. Remote or systemic actions of Phenol Poisoning : These are Shock : It is due to both local corrosive and the more CNS depressant systemic action. Sci. It is to be noted that antiseptics do not heal wounds. Mechanism of action of phenolic disinfectants VIII. [Incorporation of labelled amino acids in subcellular structures of Micrococcus lysodeikticus protoplasts]. Hence, they are better described as “disinfectants.” When To Use Both A Cleaner And A Disinfectant If both cleaning and disinfection of a surface is required, then one employs a liquid containing both a cleaning agent (typically, a detergent) and a substituted phenolic disinfectant (o-phenylphenol, for example, which avoids the toxicity, carcinogenicity, and corrosive nature of pure phenol). Binding of selected phenol derivatives to human serum proteins. A lot of studies have been conducted to find the mechanism of action behind these properties. (1) Sources and Potential Exposure Human serum γ globulin in the same concentration as serum albumin did not reduce binding of the labeled phenols to the bacterial cells while a sonic disintegrate of M. lysodeikticus cells caused some reduction in binding.

Phenol and its derivatives exhibit several types of bactericidal action. Phenols have been used for a long period of time as a disinfectant. Cetrimide. o-Phthalaldehyde is a disinfectant with potent bactericidal and sporicidal activity and has been suggested as a replacement for glutaraldehyde in endoscope disinfection. The phenol derivatives did not cause leakage of significant amounts of radioactivity from heat‐treated cells, and cells exposed to n‐butanol (which breaks the osmotic barrier) did release additional radioactivity when treated with p‐chloro‐m‐xylenol or phenol, but the total counts … Today, carbolic acid i… The disinfectant mechanism may operate on the cytoplasm and nucleus at the chromosome level. Viricidal activity and mechanisms of action of biocides. Jon E. Starr. Phenol has been used to disinfect skin and to relieve itching. Phenol has occupied a prominent place in the field of hospital disinfection since its initial use as a germicide by Lister in his pioneering work on antiseptic surgery. The mechanism of action causes biosynthetic alterations in cellular metabolism and phospholipid destruction, formation of chloramines that interfere in cellular metabolism, oxidative action with irreversible enzymatic inactivation in bacteria, and lipid and fatty acid degradation. 2 Early studies on the action of such compounds concentrated on the kinetics of bacterial inactivation, 3 although Cooper 4 notably described the relationship between phenolics (phenol and meta-cresol) and bacterial proteins as being of importance in their mechanism … Peroxygen compounds also kill spores by removing proteins from the spore coat, exposing its core to the lethal disinfectant.
