The disk diffusion test (also known as the agar diffusion test, Kirby–Bauer test, disc-diffusion antibiotic susceptibility test, disc-diffusion antibiotic sensitivity test and KB test) is a culture-based microbiology assay used in diagnostic and drug discovery laboratories. In diagnostic labs, the assay is used to determine the susceptibility ...
The disc diffusion method involves selecting a strain of bacteria, placing it on an agar plate, and observing bacterial growth near antibiotic-impregnated discs. [12] This is also called the Kirby-Bauer method, [13] although modified methods are also used. [14]
The double-disc synergy test (DDST) utilizes two of these disks on the cultivated agar solution, either infused with a different antimicrobial solution. [ 2 ] This test was recommended the standard by the Clinical and Laboratory Standards Institute in 2004 for its use against MRSA . [ 3 ]
The first self-assessment based on Marston's DISC theory was created in 1956 by Walter Clarke, an industrial psychologist. In 1956, Clarke created the Activity Vector Analysis, a checklist of adjectives on which he asked people to indicate descriptions that were accurate about themselves. [6]
Sulphide Indole Motility (SIM) medium is a bacterial growth medium which tests for the ability to reduce sulfates, the ability to produce indoles, and motility. [1] This combination of challenges in one mixture is convenient and commercially available in stab tubes.
DiSC as a personality assessment of a person will change for a person over time or for a different environment. DiSC assessments might possibly be done on another person. A person's spouse or family might assess a person totally different than how their co-workers. In Contrast, a Myer-Briggs assessment is your innate personality preferences.
Mutations in the intercalated disc gene are responsible for various cardiomyopathies that can lead to heart failure. [2] Ruptured intercalated discs, in this case regarded as a visual artifact. Ruptured intercalated discs, when seen on histopathology, have two main causes: Microtome sectioning, thereby being a visual artifact. [4]
A strip of filter paper impregnated with diphtheria antitoxin is buried just beneath the surface of a special agar plate before the agar hardens. Strains to be tested are streaked with known positive and known negative toxigenic strains on the agar's surface in a line across the plate, and at a right angle to the antitoxin paper strip.
