Table 3 Optical density of IgM ELISA against HspX obtained for the different groups according to their vaccination status.

From: Humoral response to HspX and GlcB to previous and recent infection by Mycobacterium tuberculosis

  IgM HspX
  BCG (-) m ± sd old BCG m ± sd recent BCGb m ± sd
Uninfected 1.154 ± 0.481 1.108 ± 0.511 0.927 ± 0.535
LTBI 1.035 ± 0.622 0.986 ± 0.445 0.991 ± 0.744
r LTBI 1,580 ± 0.505 1,328 ± 0.477 1,560a
  1. LTBI = latent tuberculosis infection; m = mean of optical density; sd = standard deviation
  2. a Only one HCW had recent BCG vaccination (last five years).
  3. b Vaccination in the last five years. There was no influence of BCG vaccination to the IgM responses for HspX.
