Example sentencesExamples

Primary syphilis is diagnosed by dark-field microscopy of a suspected lesion or by serologic testing.
Given the inherent difficulties of dark-field microscopy, negative examinations on three different days are necessary before a lesion may be considered negative for T. pallidum.
He was among the first to prepare partially purified antibodies by dissociating antigen-antibody complexes and the first to use dark-field microscopy to visualize the spirochetes of syphilis.
Spirochete concentrations were determined by dark-field microscopy, and 10 4 spirochetes were injected intradermally (i.d.) into the shaved dorsal skin at the base of the tail.
