a
Abbreviations: Apc, ampicillin resistance; Gen, gentamicin resistance; Kan, kanamycin resistance; Str, streptomycin resistance; Tet, tetracycline resistance; Tei, teicoplanin resistance; Van, vancomycin resistance. The drug resistance levels (MICs) of ampicillin, gentamicin, kanamycin, streptomycin, tetracycline, teicoplanin, and vancomycin were equal to or greater than 16, 64, 1024, 512, 8, 16, and 64 μg/ml, respectively.
b
The number of strains for each of 30 different patterns was less than six.
