MIKESELL's box doe contain Ba Ames strain, but IVINS does not know if somebody else has already submitted this sample to the FBIR. These are not samples that anybody was trying to hide. MIKESELL left USAMRIID in the early to mid_1990's. MIKESELL's laboratory notebooks are in IVINS' office. Imotebooks should be in the library at USAMRIID. The library usually discards notebooks after 20 years. IVINS provided the four samples of Ba Ames strain (labeled Reference Material 1030, 7739 a,b,c) to the FBI repository in October 2003. IVINS provided Agents with a typewritten description of the 4 samples (The description summary will be submitted to the 1A section of the subfile). IVINS provided the following labels and descriptions for each of the four samples: 1) "Reference Material 1030" is comprised of Ba Ames strain spores produced by IVINS on 13 different days: 20 Nov 95, 14 Dec 95, 8 Jan 96, 22 Jan 96, 8 Feb 96, 12 Feb 96, 16 Feb 96, 19 Feb 96, 18 Mar 96, 25 Mar 96, 1 Apr 96, 15 Apr 96, 18 Nov 96. Batches of spores produced on the aforementioned dates were made in Leighton and Doi medium and purified on Renografin-76 gradients. This was found in the B-3 cold room (Roon[ | , a 4-8 degree Celsius cooler. These spores are the leftovers from aerosol challenges.
