BCG viability when combined with badger isolates of enterococci (i), weissella (ii), lactobacilli (iii) and pediococci (iv) after 0 (white bars), 24 (grey bars) and 48 (black bars) h of incubation. Co-cultures of BCG with gut-associated, Gram-negative bacteria (v) were also monitored for comparative purposes. BCG viability is expressed as log10 Relative Fluorescence Units (RFU). Data are mean ± SD with statistical analysis (Student’s t-test, *p < 0.05, **p < 0.01, ***p < 0.005) and are representative of 3 biological replicates each
