Intermediate level disinfectant means a disinfectant that kills all microbial pathogens except bacterial endospores, when used as recommended by the manufacturer. It is bactericidal , tuberculocidal , fungicidal (against asexual spores but not necessarily dried chlamydospores or sexual spores ), and virucidal .
A mechanism of action of a chemical could be "binding to DNA" while its broader mode of action would be "transcriptional regulation". [3] However, there is no clear consensus and the term mode of action is also often used, especially in the study of pesticides, to describe molecular mechanisms such as action on specific nuclear receptors or ...
An illustration shows the different effects of the bacteriostatic agent and bactericidal agent. A bacteriostatic agent or bacteriostat, abbreviated Bstatic, is a biological or chemical agent that stops bacteria from reproducing, while not necessarily killing them otherwise.
As antiseptics (i.e., germicide agents that can be used on human or animal body, skin, mucosae, wounds and the like), few of the above-mentioned disinfectants can be used, under proper conditions (mainly concentration, pH, temperature and toxicity toward humans and animals). Among them, some important are
In some literature articles, the terms "mechanism of action" and "mode of action" are used interchangeably, typically referring to the way in which the drug interacts and produces a medical effect. However, in actuality, a mode of action describes functional or anatomical changes, at the cellular level, resulting from the exposure of a living ...
For cresol bactericides or disinfectants the mechanism of action is due to the destruction of bacterial cell membranes. [7] [8] Most recently, cresols have been used to create a breakthrough in manufacturing carbon nanotubes at scale that are separated and not twisted, without additional chemicals that change the surface properties of the ...
This is the mechanism of bleaches based on chlorine but also of oxygen-anions which react through the initial nucleophilic attack. [12] A reducing bleach works by converting double bonds in the chromophore into single bonds. This eliminates the ability of the chromophore to absorb visible light. This is the mechanism of bleaches based on sulfur ...
Chloroxylenol, also known as para-chloro-meta-xylenol (PCMX), is a chlorine substituted phenol with a white to off-white appearance and a phenolic odor.. The discovery of chloroxylenol was the result of efforts to produce improved antiseptics that began at the end of the 1800s, when scientists gradually realized that more substituted and more lipophilic phenols are less toxic, less irritant ...
