PG - 7-9 LID - S0167-7012(16)30260-3 [pii] LID - 10.1016/j.mimet.2016.09.010 [doi] AB - We describe a simplified Mycobacterial Growth Inhibition Assay (MGIA) for pre-clinical assessment of vaccine-mediated protection in mice. The assay is accomplished by directly infecting splenocytes from vaccinated mice with Mycobacterium tuberculosis and quantifying mycobacteria using Mycobacterial Growth Indicator Tubes (MGIT). Vaccine-mediated immunogenicity detected by this assay correlated with protection. CI - Published by Elsevier B.V.
