An example of such testing is antibiotic susceptibility testing by measurement of minimum inhibitory concentration which is routinely used in medical microbiology and research. If a suspension used is too heavy or too dilute, an erroneous result (either falsely resistant or falsely susceptible) for any given antimicrobial agent could occur.
CLED agar (cystine–lactose–electrolyte-deficient agar or medium) is a valuable non-inhibitory growth medium used in the isolation and differentiation of urinary microbes. It contains cystine and lactose and is electrolyte -deficient; the latter trait prevents the swarming of Proteus species.
Hardy Diagnostics is an American company that manufactures and sells bacteriological culture media, reagents, automated microscope slide staining machines, and rapid identification kits for microbiological testing in clinical, research, and industrial laboratories. The company's culture media is useful in the detection of bacterial pathogens ...
[1] [9] The results of antimicrobial susceptibility tests performed during a given time period can be compiled, usually in the form of a table, to form an antibiogram. [ 31 ] [ 32 ] Antibiograms help the clinician to select the best empiric antimicrobial therapy based on the local resistance patterns until the laboratory test results are available.
TSI agar slant results: (from left) preinoculated (as control), P. aeruginosa, E. coli, Salmonella Typhimurium, Shigella flexneri The Triple Sugar Iron (TSI) test is a microbiological test roughly named for its ability to test a microorganism's ability to ferment sugars and to produce hydrogen sulfide.

An agar plate being viewed in an electronic colony counter Example of a workup algorithm of possible bacterial infection in cases with no specifically requested targets (non-bacteria, mycobacteria etc.), with most common situations and agents seen in a New England community hospital setting. Different agar plates are used for different specimen ...
Into a second flask, add charcoal, yeast extract, alpha-keto-glutarate, and agar. Mix the dry powders. Pour the buffer solution into the second flask containing the dry powders and mix. Carefully heat to dissolve the agar, then sterilize by autoclaving at 121 °C for 15 minutes. Immediately place the medium in 50 °C water bath.
Immunodiffusion is a laboratory technique used to detect and quantify antigens and antibodies by observing their interactions within a gel medium. [1] This technique involves the diffusion of antigens and antibodies through a gel, usually agar, resulting in the formation of a visible precipitate when they interact.
