SPN and infection: At the end of the co-culture with Spn, the formation of an inhibitory ring with a 20-mm diameter was observed around GB24T, indicating that GB24T was able to inhibit the growth of Spn. As shown in Figures 1B,C, the viability of BEAS-2B cells was at a high level (> 90%) after 2.0 h (110.0% ± 2.9%) of Spn infection (MOI = 20) or 1.5 h (99.7% ± 2.2 and 93.2% ± 6.3%) of GB24T (MOI = 20 and 40) infection.
