highly significantP < 0.005
When groups of individuals were analyzed, it was observed that there was highly significant control of bacterial replication in the presence vs. the absence of non-adherent PBMC from vaccinees ( n = 11); P < 0.005 for cultures with LVS-infected or SCHU S4-infected cells, whereas addition of non-adherent PBMC from naïve individuals ( n = 11) did not result in significant control ( P > 0.05) of bacterial numbers in any of the cultures (data not shown).
