Wirtz-Conklin spore stains of tissue imprints were prepared from luminescent tissues harvested at 1 h (A and B) and 24 h (C and D) post-intranasal infection with B. anthracis transformed with pPS12. (A and B) Tissue imprints taken 1 h postinfection showed macrophages with intracellular malachite green-stained spores (arrows) and extracellular spores (asterisks). (C and D) Tissue imprints made at 24 h postinfection showed macrophages and numerous polymorphonuclear leukocytes with intracellular spores (arrows). Magnification, ×100.
