FIG. 5.

Corresponding bright-field (A) and immunofluorescent (B) microscopic images showing the labeling of S. schenckii yeast cells by MAb 2G7 (anti-S. schenckii melanin MAb) in a hamster testicle and corresponding bright-field (C) and immunofluorescent (D) microscopic images showing particles recovered from a hamster testicle (as described above) following treatment of the tissue with enzymes, denaturant, and hot acid, after preparations were reacted with anti-S. schenckii melanin MAb 7C5. The particles are similar in size and shape to S. schenckii yeast cells. Bars, 5 μm.
