Figure 2. Intensity of antimicrobial activity.

Figure 2

Variation in the inhibitory intensity against each indicator strain by symbiotic bacteria isolated from the uropygial gland secretion of hoopoes. (SA: S. aureus; ML: M. luteus; LM: L. monocytogenes; LL: L. lactis; LI: L. innocua; BL: B. licheniformis; EF: E. faecium; S47: E. faecalis). Intensity of antagonistic activity: 0 (no halo), 1 (ring width <1 mm), 2 (ring width = 1–2 mm), 3 (ring width = 3–4 mm), and 4 (ring width >4 mm.).
