The susceptibility of bacteria, particularly those derived from body fluids, to antimicrobial agents is determined in terms of an ATP index measured by culturing a bacterium in a growth medium, assaying the amount of ATP in a sample of the cultured bacterium by measuring the amount of luminescent light emitted when the bacterial ATP is reacted with a luciferase-luciferin mixture, subjecting the sample of the cultured bacterium to an antibiotic agent and assaying the amount of bacterial adenosine triphosphate after treatment with the antibiotic by measuring the luminescent light resulting from the reaction, whereby the ATP index is determined from the values obtained from the assay procedures. Unbeknownst to her or her family, a sample of her cells had been sent to a nearby tissue lab, where instead of dying quickly, they doubled every 20 to 24 hours according to Johns Hopkins. While designing instruments for the Mars Viking spacecraft, Chappelle became interested in bioluminescence, which is warm light produced by living organisms. An improved method is provided for determining bacterial levels, especially in samples of aqueous physiological fluids, which method depends on the quantitative determination of bacterial adenosine triphosphate (ATP) in the presence of non-bacterial ATP. Later, he developed techniques that are still widely used for the detection of bacteria in urine, blood, spinal fluids, drinking water, and foods. mentoring high school and college students of minority backgrounds.
