| Description: | These thin agar culture plates reveal the results of a drug susceptibility test on Mycobacterium tuberculosis bacteria. Note that PHIL 16464 also shows results of this same test, using the same organisms and growth medium, however, at that point in the test, it seems that the photograph was obtained at a later time due to the presence of additional colonization in the upper dish quadrant, marked 107.
The agar medium is imbibed with various drugs to determine to which medications the bacteria are susceptible. Though in this case it is not known what drugs are being tested, it is apparent that each had a different effect on the organism’s survival. |
