Boosting with poxviruses enhances Mycobacterium bovis BCG efficacy against tuberculosis in guinea pigs.

abstract：:Carbon storage regulator A (CsrA) is an RNA binding protein that has been characterized in many bacterial species to play a central regulatory role by modulating several metabolic processes. We recently showed that a homolog of CsrA in Borrelia burgdorferi (CsrA(Bb), BB0184) was upregulated in response to propagation ...
