Ivins make very large _ Peeve was very knowledgeable of spore production, but never saw him make the preps. Ivins would determine the LD-50 of pathogenic organisms with mice. Ivins used BALB-C and CBA-J mice, per the publications. Because of his work with spores, Ivins would do weekly spore check swipes of the bacteriology suites, and there would occasionally be a small contamination somewhere in the lab (e.g. phone, doorknob). not aware of anyone lyophilizing B. anthracis at USAMRIID.
