Disinfectants are generally distinguished from other antimicrobial agents such as antibiotics, which destroy microorganisms within the body, and antiseptics, which destroy microorganisms on living tissue. Disinfectants are also different from biocides—the latter are intended to destroy all forms of life, not just microorganisms. Disinfectants ...
Multiple compounds are being developed and tested for their microbicidal activity in clinical trials. Microbicides can be formulated in various delivery systems including gels , creams , lotions , aerosol sprays , tablets or films (which must be used near the time of sexual intercourse ) and sponges and vaginal rings (or other devices that ...
Microorganisms growing on an agar plate. Sterilization (British English: sterilisation) refers to any process that removes, kills, or deactivates all forms of life (particularly microorganisms such as fungi, bacteria, spores, and unicellular eukaryotic organisms) and other biological agents (such as prions or viruses) present in fluid or on a specific surface or object. [1]
An antimicrobial is an agent that kills microorganisms (microbicide) or stops their growth (bacteriostatic agent). [1] Antimicrobial medicines can be grouped according to the microorganisms they act primarily against. For example, antibiotics are used against bacteria, and antifungals are used against fungi. They can also be classified ...
Each mentioned item in the list has different microbicidal activity, i.e. some viruses can be more or less resistant. For example, Poliovirus is resistant to a solution of 3% H 2 O 2 even after a contact time of 10 minutes, [ 59 ] however 7.5% H 2 O 2 takes 30 minutes to inactivate over 99.9% of Poliovirus. [ 7 ]
The supposed superiority of bactericidal agents over bacteriostatic agents is of little relevance when treating the vast majority of infections with gram-positive bacteria, particularly in patients with uncomplicated infections and noncompromised immune systems. Bacteriostatic agents have been effectively used for treatment that are considered ...
Other liquid sterilants, such as peracetic acid, may also be used for sterilization and may raise similar occupational health issues. [5] Sterilization means the complete destruction of all biological life (including viruses and sporoidal forms of bacteria ), and sterilization efficacy is typically considered adequate if less than one in a ...
A bacteriostatic agent or bacteriostat, abbreviated Bstatic, is a biological or chemical agent that stops bacteria from reproducing, while not necessarily killing them otherwise. Depending on their application, bacteriostatic antibiotics , disinfectants , antiseptics and preservatives can be distinguished.
