    Area of Science:

    • Microbiology
    • Immunology
    • Analytical Chemistry

    Background:

    • Microbiological assays often require precise measurement of substance diffusion in agar.
    • Accurate and permanent records are crucial for reproducibility and quality control in laboratory testing.

    Purpose of the Study:

    • To evaluate the utility of photogrammetry as a method for documenting microbiological diffusion assays.
    • To compare the accuracy of photogrammetry with direct measurement techniques.

    Main Methods:

    • Utilizing photograms (photographic records) to document the diffusion of substances within agar media.
    • Comparing measurements obtained from photograms with those from direct measurement methods.

    Main Results:
