Reference: 279A-WF-222936-USAMRIID Serial 795 Enclosures: 1) Diagram of aerosol challenge equipment, 2) Three (3) pictures of flask containing RMR 1029. Details: The USAMRIID facility located in Fort Detrick, Frederick, Maryland, houses a service division which specializes in exposing test animals to known pathogens and toxins for the purpose of "challenging" the efficacy of vaccines given to the animals prior to exposure. The vaccines are under development by other USAMRIID divisions or other laboratories which use the services of the Aerobiology Division for the challenges. The pathogens and toxins used are in liquid aerosol form when sprayed into the exposure chambers containing test animals. In an attempt to identify potential sources of Ames strain Ba spores which could theoretically have been used in the preparation of anthrax-laced letters mailed in September and October 2001, the history of Ames aerosol challenges at USAMRIID from 1996 through 2001 was compiled. From 12/9/1996 through 10/2001 there were 53 separate aerosol challenges involving Ba on 35 different days. The b7c _ | |
