The terms sterilization and disinfectionare often times used in place of one another. There are major differences inthese terms though. Sterilization involves the killing or removing all livingcells from an object (Willey, Sherwood, & Woolverton, 2017, p. 173).“Disinfection is the killing, inhibition, or removal of microorganisms that maycause disease” (Willey, Sherwood, & Woolverton, 2017, p. 173). This leavesmany so called good bacteria living. Basically, sterilization kills or removesall microorganisms, while disinfection only kills or removes harmfulmicroorganisms. Many antimicrobial chemical agents are disinfectants, becausesterilization is often very harmful to users. It requires very specific usagein order to not be harmful to people (Willey, Sherwood, & Woolverton, 2017,p. 183). Sterilization often requires prolonged exposure to the substance inorder to kill all microorganisms. This is often used on medical equipment andin surgical rooms in order to reduce infection risk (Willey, Sherwood, &Woolverton, 2017, p. 183). Many of these chemicals must be diluted in order forsafe use. There are several properties of an antimicrobial agent that make it agood disinfectant. Disinfectants must be effective in destroyingmicroorganisms, but also safe to use. They should be able to be stored for longterm use, be effective in killing or removal of harmful microorganisms withoutbeing harmful to the user. Disinfecting agents must also be cost effective.They should also not have a overly strong or unpleasant smell (Willey,Sherwood, & Woolverton, 2017, p. 180).

Quorum sensing is like the communication forone bacteria to another “cell-cell communication”. This communication betweencells is very important because the development of these organisms rely on it.Gram-positive and Gram-negative bacteria use quorum sensing communicationcircuits to regulate the process of development of multicellular organisms.These processes include symbiosis, virulence, antibiotic production, motility,and biofilm formation. Gram-negative bacteria use acylated homoserine lactonesas autoinducers, and Gram-positive bacteria use processed oligo-peptides tocommunicate. These new discoveries can help figure out which bacteria willrespond to the different drug treatments. Learning the way that these cellscommunicate with on another will help build stronger drugs. Biofilm formationputs treatments for infectious disease in a very challenging place. It allowsthe cells to attach to many surfaces and is very resistant to most treatments.The biofim formation created a better environment for bacteria to survive,making them stronger and harder to get rid of.
