Figure 1: No correlation between in vitro mycobacterial growth in whole blood and PBMC.
From: The influence of haemoglobin and iron on in vitro mycobacterial growth inhibition assays

Spearman’s correlation between BCG Pasteur growth in the whole blood and PBMC MGIT assays in 10 healthy human volunteers at (a) week 0, (b) week 4, (c) week 8 and (d) week 24 following BCG vaccination. Previously BCG vaccinated and naïve volunteers were grouped together. Points represent the mean of duplicate cultures. Δ log10 CFU = (log10 CFU of sample − log10 CFU of control).
