(A) Effect of CAB-E2 and E4 on the growth of MRSA isolates and reference strain. Antibacterial activity of CAB extracts on (a) MRSA ATCC 33591, (b) MRSA-20, (c) MRSA-44, (d) MRSA-45, (e) MRSA-395, and (f) MRSA-410. Wells 1, 2, 3, 4, and, 5 contained CAB-E2 (100 μg), CAB-E4 (100 μg), cell-free culture supernatant of CAB-E2 (100 μL), cell-free culture supernatant of CAB-E4 (100 μL), ethyl acetate (100 μL) respectively, and well 6 served as the negative control in all plates. (B) Effect of CAB-E2 and E4 on the growth of MSSA isolates and reference strain. Antibacterial activity of CAB extracts on (a) MSSA ATCC 11632, (b) MSSA-A8, (c) MSSA-46, (d) MSSA-51, (e) MSSA-84 and, (f) MSSA-79. Wells 1, 2, 3, 4, and 5 contained CAB-E2 (100 μg), CAB-E4 (100 μg), cell-free culture supernatant of CAB-E2 (100 μL), cell-free culture supernatant of CAB-E4 (100 μL), ethyl acetate (100 μL) respectively, and well 6 served as the negative control in all plates.
