Examination was made of crystalline formations derived from the Girard-Robic EV strain of Pasteurella pestis, under polarized light and under fluorescent light. Under polarized light, with a red sensitive class I filter, they have a color ranging from yellowish white to straw yellow. Under fluorescent light, they emit an intense greenish yellow radiation. Under the microscope, in polarized light, these preparations most frequently display elements having the appearance of bundles of slender, rectilinear needles.
