Comparison between different groups
A1: A and LYS	—	31.2	—	62.0	—	17.5
B1: B and AZM	—	30.6	—	53.6	—	19.7
A2: A and AMK	—	19.3	—	59.6	—	27.1
B2: B and AMK	—	75.2	—	47.7	—	49.4

The values of OD are shown in (SD). The percentage was defined as . MRSE 61, MRSE 62, and MRSE 63 represented three different clinical isolates. , , and compared with the control. MRSE: methicillin-resistant Staphylococcus epidermidis; OD: optical density; MTT: methylthiazolyldiphenyl-tetrazolium bromide; LYS: lysozyme; AZM: azithromycin; AMK: amikacin; –: not tested.
