At the request of the Environmental Protection Agency, we performed immunological biological monitoring for exposure to Bacillus anthracis (Ba) on workers conducting environmental sampling in response to the October, 2001 terror attack at the American Media, Inc., building In Boca Raton, FL. We developed, validated and used a fluorescent covalent microsphere immunoassay (FCMIA) to measure anti-Ba-protective antigen (PA) IgG in workers' sera. The FCMIA gave 4 positive anti-PA IgG results. The positive sera were the pre-entry and follow-up samples of two workers who had received their last dose of anthrax vaccine In 2000. We also compared the FCMIA to a Centers for Disease Control standardized enzyme-linked immunosorbent assay (ELISA) for anti-PA IgG (Emerg Infect Dis 8:1103-10, 2002). A high positive correlation (R=0.923, P <0.001) was observed when 20 other samples were co-analyzed for anti-PA IgG in a double-masked analysis using FCMIA and ELISA.
