Sterilant means a chemical agent which is used to sterilize critical medical devices or medical instruments. A sterilant kills all micro-organisms with the result that the sterility assurance level of a microbial survivor is less than 10^-6. Sterilant gases are not within this scope. [citation needed]
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 ...
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]
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 ]
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 ...
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.
Production of antibiotics is a naturally occurring event, that thanks to advances in science can now be replicated and improved upon in laboratory settings. Due to the discovery of penicillin by Alexander Fleming , and the efforts of Florey and Chain in 1938, large-scale, pharmaceutical production of antibiotics has been made possible.
