BCG survival rate 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 survival is expressed as log10 CFU/mL. Data are mean ± SD with statistical analysis (Student’s t-test, *p < 0.05, **p < 0.01, ***p < 0.005) and are representative of three biological replicates each
