The terms sterilization and disinfection
are often times used in place of one another. There are major differences in
these terms though. Sterilization involves the killing or removing all living
cells from an object (Willey, Sherwood, & Woolverton, 2017, p. 173).
“Disinfection is the killing, inhibition, or removal of microorganisms that may
cause disease” (Willey, Sherwood, & Woolverton, 2017, p. 173). This leaves
many so called good bacteria living. Basically, sterilization kills or removes
all microorganisms, while disinfection only kills or removes harmful
microorganisms. Many antimicrobial chemical agents are disinfectants, because
sterilization is often very harmful to users. It requires very specific usage
in order to not be harmful to people (Willey, Sherwood, & Woolverton, 2017,
p. 183). Sterilization often requires prolonged exposure to the substance in
order to kill all microorganisms. This is often used on medical equipment and
in surgical rooms in order to reduce infection risk (Willey, Sherwood, &
Woolverton, 2017, p. 183). Many of these chemicals must be diluted in order for
safe use. There are several properties of an antimicrobial agent that make it a
good disinfectant. Disinfectants must be effective in destroying
microorganisms, but also safe to use. They should be able to be stored for long
term use, be effective in killing or removal of harmful microorganisms without
being 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 for
one bacteria to another “cell-cell communication”. This communication between
cells is very important because the development of these organisms rely on it.
Gram-positive and Gram-negative bacteria use quorum sensing communication
circuits 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 lactones
as autoinducers, and Gram-positive bacteria use processed oligo-peptides to
communicate. These new discoveries can help figure out which bacteria will
respond to the different drug treatments. Learning the way that these cells
communicate with on another will help build stronger drugs. Biofilm formation
puts treatments for infectious disease in a very challenging place. It allows
the 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.
